POWER SYSTEM INTEGRITY PROTECTION SCHEMES


OVERVIEW OF POWER SYSTEM INTEGRITY PROTECTION SCHEMES

Power system integrity protection IEDs are designed to react on ab-normal electric power system conditions and faults with the aim of elec-tric power system recovery to normal operating mode. Two main tasks stipulate presence of system integrity protection IEDs:

• protection of the equipment against failures;• increasing of power transmission capacity.There may be defined two levels of power system integrity protection

schemes: local and centralized. IEDs of these two levels differ by the data volumes processed and by the set of implemented functions. Local integrity protection IEDs process data belonging to one or two bays; centralized integrity protection IEDs collect and process data belonging to a subset of bays related to the specific area, including both generating facilities and substations.

As a rule, centralized power system integrity protection IEDs operate under control of the specific system - centralized integrity protection scheme control and processing complex - which is controlled by System Operator. Local integrity protection IEDs usually operate according to the algorithms which were introduced at commissioning stage.

For implementation of local power system integrity protection scheme functions Prosoft-Systems offers MKPA, MKPA-2 and TPA-01 IEDs. Centralized power system integrity protection systems are imple-mented using UPAE IED.

The list of algorithms, which can be implemented using Prosoft-Sys-tem products, is presented in Table 1.

11SOLUTIONS FOR POWER SYSTEMS

Simplified electric power facility system integrity protection scheme architecture is shown in Figure 1. All integrity protection IEDs receive data from primary equipment (current and voltage transformers, cir-cuit-breakers, disconnectors), measurement transducers, protection relays and control devices. Pre-fault and fault signals from remote facil-ities are transmitted over power line carrier or over fiber-optic commu-nication channels, deployed with application of AVANT K400 and UPK-C devices. As shown in Figure 1, local integrity protection IEDs, operating

according to internal algorithms, can provide data to centralized integrity protection devices. For example: MKPA device can implement specific algorithm (asynchronous mode protection or overvoltage protection) and can generate control signals on circuit-breakers of the specific line. If line has been tripped and MKPA device identified that, it generates specific signal for UPAE IED. This signal is a standard UPAE initiation signal. Whether any control signals are generated by UPAE or not - de-pends on the specific configuration.

Remote HMI

System integrity protection local area network topology is shown in Figure 2. LAN is based on two independent Ethernet networks. Each net-work is implemented using industrial managed switches. The following units are part of the LAN:

• UPAE IEDs.• Local system integrity protection devices (MKPA, MKPA-2).• UPAE HMIs.• Pre-fault data sources (for example, measurement transducers,

temperature measurement devices, etc.).System integrity protection LAN is designed for the implementation

of pre-fault data exchange using IEC 60870-5-104 protocol over TCP/IP connection. IEC 61850-8-1 (GOOSE) is also supported.

It is common to integrate system integrity protection IEDs in process control systems and this is provided not only for the purpose of trans-

mitting data from these IEDs to higher control levels but for pre-fault data acquisition (from remote facilities). It is recommended to separate process control and system integrity protection LANs using gateways. System integrity protection IEDs are integrated in a process control sys-tem using IEC 60870-5-101 protocol.

Dedicated redundant communication channel is provided for the transmission of control signals from centralized system integrity protec-tion processing complex to UPAE devices. This communication channel provides data transfer with 64 kBit/s rate.

System integrity protection IEDs must have 100% redundancy of input and output circuits, control units and communciation channels between system devices and with adjacent systems.


TPA-01 APPLICATION SCENARIO

TPA-01 is microprocessor-based system integrity protection IED, which can be applied in 110 / 35 / 10 kV substations. TPA-01 is supplied as a stand-alone device for installation in existing panels or in a prefabricated panel. One panel may include one or two IEDs plus additional equipment (testing switches, auxiliary relays, indication elements, etc.). TPA-01 advantages include possibility of user-defined logics implementation, configuration flexibility at commissioning and maintenance stages. TPA-01 is capable of implementing several standard functions (automatic load shedding, frequency controlled automatic reclosing, undervoltage protection, etc.) given that necessary number of analog inputs, binary inputs and outputs is available.

Figure 3 illustrates an example of automatic load shedding / undervoltage protection at two 10 kV busbars in 110 / 10 kV substation. TPA-01 IED is monitoring phase voltages (Ua, Ub, Uc) at 10 kV busbars and if voltage or frequency drops below preset value it generates B11…B14 circuit-breakers tripping signals. Input signals are introduced using switches located in panel or using external dry-contacts.

TPA-01 IED is also capable of generating control signals for reclosing of previously tripped circuit-breakers (automatic reclosing).

MKPA AND MKPA-2 APPLICATION SCENARIO

Any standard or custom system integrity protection functions can be implemented using MKPA and MKPA-2 devices. The difference between MKPA and MKPA-2 is in the number of binary inputs and outputs. Device is mounted in a standard 800x600x2200 mm panel. It can be easily mounted in 19” panel.

These IEDs may implement several functions simultaneously given that there is a required number of analog inputs, binary inputs and out-puts. MKPA and MKPA-2 algorithms may be based on user-defined algo-rithms. These devices provide flexible configuration at commissioning and maintenance stages.

Figure 4 illustrates an example when asynchronous mode elimination and equipment overload protection functions are implemented using two MKPA IEDs. Line asynchronous mode elimination function is implement-ed to identify asynchronous mode using line parameters and to initiate control signals for electric power network decoupling.

Equipment overload protection is implemented to identify increased power flow over power line in a certain direction and to initiate spe-cific control signals. Figure 4 illustrates two electric power generation facilities and one substation. When there are no faults in the system, generators at operate in synchronous mode. Due to specific reasons (for example, line fault), generators synchronous operation may be disturbed.

MKPA must obtain data about three phase currents (Ia, Ib, Ic) and three phase voltages (Ua, Ub, Uc) of the supervised bay. To enable sec-ondary circuits failures supervision function, MKPA must also obtain

voltages from VT open delta winding. As it can be seen, it is required to process 9 analog values to implement asynchronous mode elimination function. All other parameters required to implement algorithm (power, resistance, etc.) are calculated on the basis of phase currents and volt-ages. Equipment overload protection function requires the same three phase currents and three phase voltages. Given that it is reasonable that two mentioned functions reside in the single IED (as shown in Fig-ure 4). Ambient temperature measurements, required for the correct operation of equipment overload protection function are introduced in MKPA using UNC-1 IED. The latter receives measurements from the remote sensor and sends data over Ethernet network using GOOSE messages (IEC 61850-1).

Trip signals are transferred to specific circuit-breakers. Along with trip signals, automatic reclosing inhibit signals are generated. After decoupling, network original schema restoration is only possible by op-erator. Figure 4 shows two MKPA IEDs, operating in a hot standby mode. They perform the same asynchronous mode elimination function on the same bay, providing control signals for the specific circuit-breakers.

Equipment overload protection function generates control signals for circuit-breakers of the feeders, providing power supply of the customers. In Figure 4 such circuit-breaker is B4, which is remote for MKPA IED, implementing this function. In this case control signals are transferred to the remote facility over fiber-optic communication chan-nel via AVANT K400.

IMPLEMENTING ELECTRIC POWER SYSTEM STABILITY DISTURBANCE PREVENTION FUNCTION AND SPECIAL LOAD SHEDDING FUNCTION USING UPAE IED

Electric power system stability disturbance prevention function relies on specific power system stability calculation results, given all possible operating modes. Special load shedding function generates trip signals for circuit-breakers of the feeders, providing power supply to the end-customers. These functions are implemented in 500 kV sub-stations. Specific substation is chosen on the basis of available com-munication channels with remote substations, generation facilities and control center. Mentioned functions can be implemented using UPAE IED. System architecture is presented in Figure 5.

UPAE operation principle relies on 2-BEFORE principle. This means that at the moment of fault indication reception IED already includes prepared table of control signals and in case of fault indication recep-tion it is only required to select required set of control signals. All table data is introduced at commissioning stage or received by UPAE IEDs from centralized system integrity protection over specific communica-tion channel. If connection with these IEDs is available and all data is loaded, UPAE is functioning as a remote controller of special integrity

protection system. If connection is lost, UPAE IED switches to local operating mode and is ready to operate according to the specific con-trol signals table.

Determination of the current configuration of the facility is per-formed on the basis of pre-fault data. Pre-fault data includes data regarding equipment maintenance: line maintenance, unit maintenance indications, etc. Power flow data is provided to UPAE as remote meas-urements in analog form or from specific transducers or from data transmission and acquisition system in digital form over LAN.

Standard initiation signal for electric power system stability distur-bance prevention function is line trip identification signal. In case this initiation signal is received, pre-fault mode is considered to be over and control signals table is determined. Then specific control actions cycle is started. In this cycle all inputs are polled at high rate (one time per 1 ms), control signals table lines are identified and control signals are issued.

IMPLEMENTING ELECTRIC POWER SYSTEM STABILITY DISTURBANCE PREVENTION FUNCTION AND STATION POWER GENERATION CONTROL FUNCTIONS USING UPAE IED

Station power generation control functions are required to preserve electric power system stability. Besides that implementation of these functions is required when station is a part of centralized system integrity protection system and may receive control signals to lower/gain power generation from centralized system. In latter case specific algorithm is implemented which is called electric power system node power generation control.

This algorithm’s aim is to supervise electric power system gen-eration units, including active power measurement. Pre-fault data is equipment status data (operation/maintenance) and signals indicating

possibility for usage of the specific power generation unit in special integrity protection schemes.

Power generation control functions may output the following binary signals: turbines unloading, power generation units or gen-erators disconnection both manually and with automatic selection of the specific units (with the following criteria taken into account: unit availability, unit capacity, manual control actions prohibition). Automatic selection of power generation units must be performed in a such way that minimum number of units must be disconnected to reach the required result.

FAULT DISTURBANCE RECORDING AND WIDE AREA MEASUREMENTS


WIDE AREA MEASUREMENTS SYSTEMS (WAMS)

Wide area measurement system is one of the new and widely intro-duced technologies in electrical power systems of the world. This is all because of the new advantages these systems are able to provide.

Wide area measurement system (WAMS) and wide area measure-ment, protection and control systems (WAMPACS) take monitoring and control functions to a completely new level. WAMS is also being imple-mented in Russian Federation.

WAMS provide a more detailed data on steady-state power system operating mode and transients, which arise due to different kind of pow-er system failures. Therefore more and more facilities are equipped with phasor measurement units (PMUs).

System Operator of Unified Power System technical regulations force WAMS implementation. These regulations do also place new re-

quirements on PMUs, force introduction of the new algorithms, increase number of monitored parameters.

Prosoft-Systems offers complete system which complies with all existing requirements. It includes PMUs, generator excitation system parameters measurement IEDs and phasor data concentrator. All system components are time synchronized using GPS/GLONASS receivers.

Prosoft-Systems also takes part in different events, devoted to WAMS, closely cooperates with System Operator of Unified Power Sys-tem, different research institutes and other WAMS suppliers.

Up to day Prosoft-Systems’ WAMS has been implemented in 5 large facilities. Total number of installed PMUs is 42, 20 of which have been installed in power generation facilities with total power of 11 GW.

FAULT RECORDING SYSTEM

Fault recording system is designed to collect, store and provide data regarding faults, their evolvement and elimination both in electric power stations and substations. This functionality provides possibility for a more accurate identification of outage reasons and evaluation of protec-tion IEDs operation correctness.

Figure 2 shows an example of fault recording system, based on RES-3 IEDs. RES-3 IEDs are located inside control rooms of considered electric power facility. These IEDs are connected to CTs/VTs and external measurement transducers. Binary signals are received from protection IEDs, control IEDs, switchgear and signals and commands transmission devices.

Waveform recording is initiated when analog signal exceeds preset value or/and by a binary signal, generated by external IED. RES-3 IED con-figuration is performed at commissioning stage or during maintenance.

Data is recorded in one of the following ways:• waveform recording of analog and binary signals both in a steady-

state mode and at faults (with sampling frequency of up to 2000 Hz per channel);

• data recording in process control system (with data transfer according TCP/IP protocol).

All fault recorders are connected in a single LAN, based on fault recording system server. Fault recording system server provides data communication with electric power facility process control system and control centers. Recorded data can be transferred either automatically or with a command, issued by operator. RES-3 system provides proprietary data visualization applications which can be installed in local HMI.

When necessary RES-3 fault recorders may be time synchronized using available GPS/GLONASS receivers.

Waveform recording initiation at specific setting violation and/or by external signal is also provided.

User is capable of setting overall duration of the waveform recorded; it is also possible to set pre-fault, fault and post-fault modes recording time. User can set number of waveform recordings, capturing consequent faults. Fault mode is identified by the whole set of available signals (analog and binary). Recordings are transferred to process control system (either automatically or by a signal from operator) for further storage and visualization on protection engineer’s HMI. It is also possible to save waveform recordings in COMTRADE format and to transfer them to higher control levels. Spectral and harmonic analysis of waveform recordings is possible. Waveform recording initiation is done in automatic way. Settings can be set for any individual channel or for combination of several channels; all settings are stored in non-volatile memory.

COMMUNICATION DEVICES & SOLUTIONS FOR RELAY AND SPECIAL INTEGRITY PROTECTION

SOLUTIONS FOR POWER SYSTEMSSOLUTIONS FOR POWER SYSTEMS

TRANSMISSION/RECEPTION SPECIAL INTEGRITY PROTECTION SCHEME SIGNALS AND COMMANDS OVER 4 KHZ POWER LINE CARRIER

Implementation of relay protection and special integrity protection schemes requires large number of signals to be transmitted between facilities.

Relay protection signals such as remote tripping and permissive overreaching (underreaching) trip scheme signals are transmitted over protected lines during faults and have higher priority over special integrity protection scheme signals.

Duplex transmission of relay protection and special integrity protection scheme signals (with 32 signals transmitted to each side) is implemented using AVANT K400 transceiver over 4 kHz power line carrier. In this case

2 kHz communication channel is available in each direction with adjacent bands (Figure 1).

Interchangeability of main modules with other devices in AVANT lineup is provided: AVANT K400 and AVANT RZSK.

When there is a requirement to transmit signals only in one direction it is possible to apply UPK-C devices, which include transmission and recep-tion modules as well as AVANT K400 (Figure 2). In this case communica-tion channel becomes simplex and AVNAT K400 implements a function of either transceiver or receiver, providing interoperability with other power line carrier devices – ANKA-AVPA, AKPA, AKA KEDR, UPK-C, VCHTO – in regard to frequency band, plan, signal level and sensitivity.

TRANSMISSION/RECEPTION OF RELAY PROTECTION AND SPECIAL INTEGRITY PROTECTION SCHEME SIGNALS OVER DIGITAL COMMUNI-CATION CHANNELS

Special version of AVANT K400 transceiver may be used for the trans-mission of relay and special integrity protection scheme signals over digi-tal communication channels.

In this case communications may be performed both over designated fiber-optic communication channels and over C37.94 interface, which allows for data communication with multiplexors, equipped with the same interface.

In its digital version AVANT K400 transceiver provides possibility to transfer and receiver up to 32 signals. It has two slots for the implemen-tation of two independent data transmission / reception channels – each of them may operate over designated fiber-optic link or over C37.94 interface.

Using this AVANT K400 version it becomes possible to implement dif-ferent communication schemes for duplex transmission of protection sig-nals over designated fiber-optic links such as point-to-point and redundant

point-to-point connections, bidirectional rings as well as simplex channel with point-multipoint redundant configuration. In the last case optical splitter is used (Figures 3, 4, 6).

Based on AVANT K400 transceiver it is possible to implement com-bined digital communication channels for protection and special integrity protection applications over different media: one slot operates over desig-nated fiber-optic link and another – over multiplexed channels (Figure 5).

Hierarchy of digital communication channels over C37.94 interface depends on capabilities of used multiplexed channels. While using SDH multiplexers it is only possible to implement point-to-point, line and ring configurations, using AVANT K400 transceivers, C37.94 interfaces, IP mul-tiplexers and designated fiber-optic channels it becomes possible to create fully isolated digital communication system for protection applications of any complexity.

Due to two slots for data transmission/reception AVANT K400 allows to design the solutions for complicated routes with ring, radial and mixed configurations of communication channels including the “point-to-multi-point” routes with several destinations from the departure point (Fig. 7).

In the latter case the transceiver performs the routing function, i.e. reassignment of a command. As a result, the commands may enter at any

node of the ring and can be discharged at different nodes in any combina-tions, up to a total of 32 commands.

Basic transmission time from one transceiver to the nearest (transit through one multiplexer) is 7 ms, the delay for one additional multiplexer is 0.4..0.6 ms. Delay inside the transceiver - 0.3 ms.

Likewise, the ring can be constructed on a designated fiber-optic link (Fig. 8). Unlike previous solution, commands packets are transported by transceiver AVANT K400.
