FOREWORD

The year 2011-12 has been a year of achievements for CPRI – especially in the Research area. Our research team managed to file 12 products/processes for patents, which included awarding patents for three. We created a record of sorts in the publishing arena – what with 217 papers getting published in a single year including 68 in the reputed international conferences and journals. Two projects for development of STATCOM for Bhilai Steel Plant, and IT park, Thiruvananthapuram taken up under National Perspective Plan are undergoing field trials. A high temperature superconducting distribution transformer of 630 kVA capacity was developed for the first time in the country through a project taken up under NPP scheme. Fifteen RC projects amounting to Rs. 731.50 lakhs and 12 RSOP projects with an outlay of Rs.361.92 lakhs have been initiated boosting our R&D efforts by leaps and bounds.

CPRI has also helped Transient Simulation Studies for 1200 kV system of PGCIL at Bina, M.P.

The Director General, CPRI, headed the sub group for the preparation of a report on Technological Advancement and Research & Development for Ministry of Power, Govt. of India. The report submitted has become part of the 12th plan document of the Ministry of Power.

On the Receipts front, the institute could realize Rs. 135.24 Cr., which is marginally less than the previous achievement of Rs.139.71 Cr. This is in spite of the general slump faced by the Indian industry as a whole in the year 2011-12.

In CPRI, people are the most important assets, and we continue to strive to create a collaborative, knowledge driven culture by focusing on our training programmes. Our training programmes have only strengthened over the years, which are well appreciated by the in-house staff members as well as participants from other organizations. The year 2011-12 saw a plethora of training programmes on subjects as varied as research based in the power sector to six sigma management to stress and time management.

CPRI was conferred with a fourth India Power Award by Council of Power Utilities in recognition of excellent work done in testing & certification of power equipment. The award was given away to the institute in a function organized on 24 Nov. 2011 in New Delhi.

Working towards its objective of strengthening the research and test facilities, CPRI added several new research and testing units during the year. Some of them are given below.

1. Load loss-No load loss test facility for transformers up to 50 MVA

2. Facility for testing On Load Tap Changers (OLTC) at STDS

3. Inductive load switching test facility for HV circuit breakers

4. Capacitor current switching test facility for circuit breakers

5. Centre for Excellence for Life Cycle management and Condition Assessment of High Voltage Substation and Power Plant Electrical Equipment

6. Creep test facility

With the phenomenal rise in pollution levels, controlling the ill-effects of pollution leading to frequent flashovers and grid collapse has become a major concern for the power sector. CPRI has entered into an agreement with Power Grid Corporation of India Limited (PGCIL), which enables transmission of power from one end of the country to the other. The two year contract includes training of Power Grid personnel in onsite pollution measurements; mapping of northern region; analysis of chemical composition of pollutants etc. The institute hopes to avoid any fiascos in power transmission due to the effect of pollution in the future.

Project Summary:

The coatings on deposited nanoceramic thin film W-Zr-N on Si (100) p type substrate through Direct/Radio Frequency (DC/RF) reactive magnetron sputtering has been developed. The effect of varying deposition parameters on the structural properties of W-Zr-N has been investigated through X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), and Energy Dispersive Spectra (EDS). By increasing the percentage of nitrogen through different techniques, the following observations were seen.

XRD Analysis

XRD analysis of the nanostructured sample shows that the preferred orientation changes of the film deposited at different temperatures ranges between room temperature and 600 degrees. The lattice arrangement of the transition element atoms in the Zirconium Tungsten Nitrite (Zr – W – N) maintains FCC structure for higher temperature. The film shows amorphous nature at low temperature. The XRD analysis also reveals that there is a reduction in the average grain size with the increase in temperature for this particular FCC phase of W – Zr – N coating. Microstructural analysis using FE–SEM reveals that the thickness of the amorphous film is higher compared to crystalline films. It is also noticed that there is variation of hardness, elastic modulus and plastic reformation energy with the variation of nitrogen partial pressure.

Project Description:

Consumers in the textile industry and other industries frequently experience the problem of electric drives tripping. Initially, the exact reason for tripping of electric drives was not known. The problem was first noticed in the textile industry, and it was found be caused by a sudden dip in voltage. This consumer tracked the rms voltage using a multifunction transducer and recorded the trend in voltage, current, frequency and so on. The problems caused by voltage sag are severe and cannot be easily solved. The exact problem faced needs to be ascertained to find a solution for the issue. Therefore, this R&D project was proposed to identify the quality issues, design a Dynamic Voltage Restorer (DVR) to overcome the problem and evaluate the end result. A DVR is primarily used at the distribution level. The DVR is not manufactured in India. This project has a very good potential in both industrial and domestic sector.

Custom power devices are a family of power electronics equipment for improving the power quality by compensating VAR, harmonics, voltage sags and voltage swells, all of which occur in the distribution side of the power system.

Voltage sag is a momentary (that is, 0.5-30 cycles) decrease in the rms voltage magnitude, usually caused by a remote fault somewhere on the power system. Voltage sags are the most important power quality problem that many industrial customers face. Equipment used in modern industrial plants (process controllers, programmable logic controllers, adjustable speed drives, robotics) are actually more sensitive to voltage sags because the complexity of the equipment is increasing. Even relays and contactors in motor starters can be sensitive to voltage sags, resulting in shutdown of a process when they drop out.


CPRI 45

DVR Voltage Stabilizer with Series Active Filter

The proposed system is a composite power quality solution that can provide a stable, sinusoidal supply voltage at the load terminals. Sufficient voltage is injected in series in to the load feeder dynamically, depending on the compensation requirement. The above figure shows the block diagram of the system. It is a combination of a series active filter and DC bus capacitors. The series active filter operates as DV). The DVR ensures sinusoidal, regulated, and balanced voltages at the load terminal. If necessary, the DVR can support the DC bus with another rectifier/converter block such that there can be a steady state power injection in the series transformer.

The DVR is a power quality device that can protect industrial consumers from most disturbances, that is, voltage sags and swells related to remote system faults. A DVR compensates for these voltage excursions, provided that the supply grid does not disconnect entirely through breaker trips.

Improvement in reliability, safety, and long term performance of power and converter

transformers through improvements in quality of transformer oil

Implementing Organization: CPRI, Bangalore

Total outlay: 90.0 lakh. Support from MoP: full. Funds released till date: Rs 50.0 lakh. Start: November 2009. Completion: December 2012. Project Status: Ongoing.

Objectives:

To improve the performance of power and converter transformers through improvements in quality assessment methodology of transformer oils

To improve oil diagnostics for improved service and extension of life of power transformers.

This investigation does a complete evaluation of transformer oils with the objective of mitigating the copper corrosion problem in power and converter transformers. The study encompasses all components of oil, including additives, inhibitors, metal passivators and others that are added to improve the quality and long term performance of oils. The importance of the project is as follows:

Failure of power and converter transformers in service has been attributed to the formation of corrosive sulphur in the transformer oil. Transformer experts from all over the world have expressed their concern about the increase in number of failures due to harmful effects of corrosive sulphur in transformer oil and an understanding of the mechanism of formation of corrosive sulphur is essential. It is also attributed to the presence of combined AC/DC stresses in the insulation system.


CPRI 47

The present problems in power transformers are:

A number of power transformer and reactor failure cases with indications of copper corrosion and formation of copper sulfides on conductors and insulating materials.

The conductive copper sulfide reduces the dielectric breakdown voltage of solid insulation. This can result in a dielectric puncture through the paper insulation.

The failures occurred after the apparatus was in service for a year or several years.

It is, therefore, necessary to test the oil for sulphur content before using it. The project aims to focus on the following:

Identifying the sources of sulphur compounds and monitoring their concentration

Analyzing the effect of sulphur compounds on dielectric parameters such as electric strength, partial discharge inception and extinction, insulation resistance and polarization index

Examining the effect of AC and DC and a combination of AC/DC stresses on paper oil insulation

Studying thermal ageing of paper-covered conductor/transformer oil at temperatures ranging from 120°C to 140°C in nitrogen, oxygen and air and studying their effects on the formation of sulphur compounds

Evolving methods to combat the problem of corrosive and reactive sulphur by using additives.

The following activities have been completed:

One C and DF apparatus was installed and preliminary measurements were carried out.

Polarization–depolarization concept based measurement of C and DF was undertaken. DIRANA received from M/s. Omicron instruments was installed and about 10 samples of paper-oil insulation with different levels of moisture content was subjected to moisture content evaluation.

About 50 samples of transformer oil drawn from power transformers in service were evaluated for mercaptan sulphur content. It was observed to be less than 1 ppm.

Design of a hot air oven with specified air changes was completed and fabrication is in progress.

An air flow control system using flow meters consisting of 16 test stations were undertaken and mechanical design was completed.

Oil samples were collected from different transformers of utilities based on their length of service and to perform physical, chemical and di-electric parameters was completed for samples of Sharavathy receiving station.

Design and development of high temperature superconducting fault current limiter

(FCL)

Implementing Organization: Crompton Greaves, Mumbai

Total outlay Rs 306.0 lakh. Mop support: 153.0 lakh. Funds released till date: Rs 76.0 lakh. Start: Nov 2009. Completion: October 2012.

Objectives:

The objectives of the project are:

To develop an 11 kV, 1250 A, 3 phase SFCL

To study the complete performance of SFCL wit in CG R&D

To evaluate SFCL at an independent laboratory

Project Description:

The purpose of the fault current limiter is to reduce the magnitude of the short circuit fault current before the circuit breaker actually clears the fault. The basic principle behind the functioning of majority of the fault current limiters is the introduction of a high impedance element in the circuit to reduce the magnitude of the fault current. The limiting of the fault current to a manageable value reduces the thermal and mechanical stresses in the system thereby enhancing the life of the switching equipment. Based on the operational characteristics, the fault current limiters are categorized as:

Inductive

Power Electronic

Resonant circuits

Electromagnetic

Superconducting Fault Current Limiter (SFCL)

The SFCL is based on the outstanding electrical properties of superconductors, which are:

Zero resistivity below a critical temperature (Tc) and a critical current (Ic).

As soon as Ic and/or Tc are surpassed by high fault currents, the resistivity of the material increases rapidly (quench).

When the surge or over current ceases, the superconductor recovers and again comes back to superconducting state.

Advantages of SFCL

SFCL eliminates the system-wide need to install higher capacity circuit breakers with a fast-acting, passive solution. As grids grow, the fault currents increase, necessitating higher capacity circuit breakers. SFCL avoids the cost incurred for upgrading and replacing the existing breakers. Thus, the overall system cost reduces. Moreover, SFCL is a fail-safe device.

SFCL reduces damage to electrical equipment due to system faults. HTS fault current limiters limits the current spike and mechanical forces caused by this surge, thereby improving the system reliability.

SFCL reduces the annual operating costs of utilities by reducing damage to electrical equipment. Acting like surge protectors, HTS fault current limiters protect downstream electrical equipment from fault currents.


CPRI 49

SFCL reduces voltage drops and AC losses. HTS FCLs can replace widely used line reactors and avoid voltage drops and ac losses inherent in such line reactors, thereby improving the power quality. Moreover, replacing conventional reactors with SFCLs would lead to a reduction in transmission and distribution losses that presently are a matter of great concern.

Thus, the development of SFCL offers great technical advantages. Importantly, this project would establish a platform for the development of indigenous SFCL products of higher system voltage, with a capacity to handle higher fault currents.

The project is proposed to be executed in two phases.

Phase 1: Design and development of HTS FCL 440V, 800A, 1-phase

Phase 2: Design and development of HTS FCL, 11kV, 1250A, 3-phase

In phase 1, the SFCL is designed as a prototype, which would generate data for Phase 2. The various parameters for SFCL design are considered from the experimental analysis and are tabulated as follows:

Table 2: SFCL Parameters

Parameters Value

Nominal current 800A

Voltage 440V

Fault current 5kA for 3 cycles & 3 kA for 5 cycles

HTS length 21.6 meters

SFCL modules 4 (each will carry 200A, 440V)

Modules materials GFRP

Temperature 77 K

In the design of the SFCL, four modules are connected in parallel. Each module carries a current of 200A. In each module, the superconducting tapes are connected in series to achieve the required voltage rating. The tapes are mounted on GFRP plates. The interconnection of the tapes for series connection as well as the parallel connection is achieved through copper plates. The interconnecting copper plates are connected to the bus bars through flexible copper braids.

The cryogenic insulation is achieved through a cryostat, which is a double-walled container. The space between the walls is evacuated and filled with multilayer thermal insulation to avoid heat transfer. The top flange of the cryostat is also evacuated. It has openings for bus bars, port for filling of liquid nitrogen and a vent for nitrogen vapors.

Development of silt erosion resistant material for turbines of hydro generators

Implementing Organization: NML, Jamshedpur

MoP share: Rs 149.0 lakhs. NHPC share: Rs 84.0 lakhs. SJVNL share Rs 20.0 lakhs. Funds released till date: Rs 253.0 lakhs Start: August 2006. Completion: June 2012. Project Status: Ongoing.

Project Objective: To develop a material with the following properties:

Stainless (corrosion) steel with properties similar to that of 13 Cr-4Ni steel


CPRI 50

Improved abrasion and erosion resistance

Improved impact toughness values for resistance to impingement erosion by silts

Damping capacity for frequency tolerance similar to 13Cr-4Ni steel

Good castability and weldability

Project Summary:

Erosion setup is made as per ASTM G-32 and characterization of Heat 2 and Heat 3. Activities related to various heat treatment parameters on silt 7 and 8 are under way to optimize erosive wear property. Slurry erosive wear studies for benchmarking 13Cr-4Ni steel are completed with the setup of IIT-Roorkee. Flow modeling through CFD analysis has been initiated. The mechanical property of the material was investigated through an automated Ball Independent technique developed at NML.

Weldability testing machines have been procured and preliminary tests are being carried out. Design for a new setup for slurry erosion with air flow is under progress. The alloys are melted and cast into a bigger size. Standard samples for tensile and impact will be prepared from these alloys and reproducibility of data will be verified. Additionally, new compositions with slight modifications of the present Alloy-8 are underway.

In the present project, 13Cr-4Ni steel has been taken as the benchmark material. The objective is to develop a material that has at least a few properties of 13Cr-4Ni steel. With the intention of understanding the damage on underwater components caused by the synergistic effects of particle impingement due to silt and cavitation induced erosion, samples of underwater parts from Salal and NJHPS were received and laboratory evaluation is being conducted.

Cavitation erosion studies have been conducted through generation of cavitation by ultrasonics. One of the new alloys has been tested and is found to have better properties than 13Cr-4Ni steel. Another alloy is under investigation.

The ultimate tensile properties were found to be similar to that of 13Cr-4Ni steel. With the same strength level, the ductility of the new alloys is quite higher compared to 13Cr-4Ni steel. This indicates high energy absorption capability for the new alloys compared to 13Cr-4Ni steel.

The strain hardening exponent is observed to be around 0.5, which shows that the material hardens during operation. This is a unique property that is not observed in 13Cr-4Ni steel. Charpy Impact properties are observed to be around 200J at room temperature compared to 40-60J for 13Cr-4Ni steel. The new alloys developed have quite lower erosion rates compared to 13Cr4Ni steel. Wear properties were measured through air-jet impingement method. Hence, the properties of the new alloys are better than 13Cr-4Ni steel. A preliminary study on weldability study shows fewer crack formations during bending of welded samples compared to 316L stainless steel. However, further work is required for the same.

Objectives:

The objective of the project is to develop an optical current transformer using optical fiber as a sensor medium. This was the first time where the Faraday Effect was used to develop an optical transformer.

The project is based on the principle that if an optical fiber carrying a polarized laser beam is wound over a conductor, then there will be a change in the polarizing angle due to the presence of a parallel magnetic field. By measuring the change in the angle, the current passing through the conductor can be obtained.

Project Summary:

The results of the optical current transformer with half cycle current and half second current were obtained.

The half second reading was found to be more reliable, thus proving the principle of the OCT based on Faraday Effect. Results of the optical current transformer and that of the conventional current transformer were compared and the agreement between the two with respect to performance was observed to be very good.

Inspection of flood damaged HV & LV cables at Indorama polymers public company

limited, Lopburi, Thailand

CPRI bagged the prestigious work order from M/s. Indorama Ventures Public Company Ltd (IVL) Thailand for inspection of flood damaged HV & LV power cables and also for witnessing the diagnostic testing of the damaged cables at the premises of the Polyethylene Terephthalate (PET) Polymers Company located at Lopburi, Thailand.

Indorama Ventures Public Company Limited (IVL) is one of the largest vertically integrated polyester producing chains in the world and a leading global manufacturer of wool yarn.

IVL established its PET (Polyethylene Terephthalate) resin facility in Thailand in 1994. The plant is certified under ISO 9001.

PET is a key material used in the petroleum industry and consumer goods companies that make bottles and packaging as well as apparel, footwear and other items used in our daily lives. PET division also produces PET packaging, including preforms, bottles, and closures. PET Polymers has eight plants with HV & LV installations comprising power transformers, circuit breakers, high voltage & low voltage cables, control panels etc. Some cables are laid underground and some are laid overhead above the cable trays at about 30 - 40 mts level and connected to different equipment. These cables have either copper/aluminium conductors.


CPRI 63

The factory premises of M/s. IVL, Lopburi, Thailand was flooded with rain water during September 2011 and many of the plants & machinery including the LV and HV cables were submerged in the rain water of about 180 cms of depth for 45 days.

Plants & Machinery Submerged in the Rain Water

Control Panels and Machinery were Damaged Due to Corrosion

After the flood water receded completely, M/s. IVL wanted to assess the extent of damage caused to the plant and machinery and also evaluate the possibility of reviving the plant by assessing the extent of damage caused to the plants, machineries and cables and trying to revive the plants with possible Refurbishment/ Repair/ Retrofitting/ Replacement.

At the invitation of M/s. IVL, Lopburi, Thailand, experts from Central Power Research Institute (CPRI), India conducted visual inspection and examination of the flood damaged HV, LV cables and panels at the site from 26 January 2012 to 01 February 2012. On visual inspection and examination, it was found that all the HV and LV cables were heavily damaged due to flood water. The metallic parts of the control panels and machinery were damaged due to corrosion as shown in photographs 5 & 6. The extent of damage to the HV and LV cables was high due to the ingress of water into the cable systems. Operational reliability of both the HV and LV cables was suspected to be poor.

HV cables

The ingress of water into the high voltage system is dangerous to the reliability and life of the HV equipment, as it reduces electrical breakdown strength and increases dielectric losses in the HV equipment.

In order to revive the HV cable installations, M/s. IVL engaged the services of M/s. PES, Thailand for extraction/removal of water from the HV cables. The methodology consists of cutting open the heat shrinkable termination at the tip of the cable terminals just below the lugs to access the conductor strands of the cables. Vacuum (-1000mb) was applied to the cable conductor strands to extract the water accumulated in the cable conductor strands.


CPRI 64

The methodology adopted by M/s. PES for removal of water from the cable system was successful as substantial quantity of water was removed from some of the cables. The HV cables subjected to vacuum pulling of water were tested for insulation resistance and tan delta at a very low frequency -- 0.1 Hz (VLF) high voltage.

CPRI experts witnessed the vacuum pulling of water from the XLPE cables and VLF testing on the XLPE cables. The diagnostic test data was analysed in detail to assess the extent of damage and the existing state & condition of the cables. After analyzing the inspection and diagnostic test data, appropriate recommendations were made to enhance the reliability of operation of the cables.

Training activities


CPRI 102

The phenomenal growth in the power sector over the last few years has magnified the need for absorption of technology in all the three spheres of activity viz. Generation, Transmission, and Distribution of power. Coupled with this is the paucity of trained technical manpower and associated skills.

Recognizing this need of the power sector, the institute has been developing and running training programmes for:

Upgrading the manpower skill of its own employees.

Training and up gradation of technical skills of personnel from utilities / companies in the power sector.

CPRI is continually setting new standards in training and continuing education from basic theoretical studies to practical hands-on training in electrical equipment.
