INTEGRATED PROTECTION AND CONTROL SYSTEM (IPCS)

The IPCS is based on ICUs (Integrat-

ed Control Units) located in each sub-

station, which communicate with the

motor starters and the protection re-

lays, making all the information avail-

able for the operator workstations

and the redundant servers installed

in the Main Control Room, and op-

erate as a gateway with the DCS,

which sends commands and receives

feedback via the TCP/IP interface.

The IPCS created for the Gasco OGD

III project not only displays the status

and alarms of all the components of the

electrical network but also greatly as-

sists the operators in maintaining the

plant because it stores the parameter

settings of all the control units (both

motor managers and protection relays)

and compiles the sequence of events

and the disturbance waves recorded by

the protection relays in case of faults.

EPC CONTRACTOR: BECHTEL / END USER: GASCO

INTELLIGENT PMCCs

The Intelligent Motor Control Centers

were equipped with an on-board touch-

screen operator interface to operate

the switchboards and compile data on

trends, alarms and event sequences.

This operator interface acts as a

gateway to the DCS (Distributed Con-

trol System) to allow the process con-

trol system to start/stop motors and

record the activation of alarms.

The PMCC switchboards were de-

signed to prevent any risk of a short

circuit and internal arc fault at 75 kA-

690 V for 0.3 seconds – to this end,

they were fully type-tested by an in-

dependent laboratory.

MV AND LV SWITCHGEAR

Skema’s Intelligent Power Motor Con-

trol Centers were designed to deal with

seismic loads at the following levels:

> Earthquake-proof construction:

Zone 4

> Peak Horizontal Ground

Acceleration: 0.83g

> Peak Vertical Ground

Acceleration: 0.59g

> Seismic Design Code:

ASCE 7/IBC 2000

The robustness of the modules was

tested in relation to the following

structural aspects:

> Resistance and stability for

individual modules

> Ground anchors

> Links between modules (bolts)

> Internal links to modules (rives)

In addition, Skema’s Switchgear was

successfully tested for seismic loads in

compliance with IEC 60068-3-3 (1 g).

The incomers, the bus-ties and the ACB

feeders of the PMCCs and the cells of

the MV switchgear are equipped with

protection relays configured accord-

ing to the IEC 61850 communica-

tion protocol. Goose signals are used

by the PMCCs to exchange informa-

tion, and by the MV cells to exchange

information and provide protection.

PACKAGED SUBSTATION

Skema supplied for the Project a 400V

Modular Primary Substation, a pre-

fabricated, modular enclosure inclu-

sive of all external appurtenances and

walkways, access ways and stairways.

The Packaged Substation is designed

for extreme outdoor conditions (-34°C

/+38°C) and incorporates the require-

ments for seismic, wind, snow and ice

loading, elevated at a typical 1,800

mm to underside of steel above site

grade on a steel support frame.

The Packaged Substation is composed

of two Modules:

> The Modular Primary Substation

(32,000 mm (L) x 4,000 mm (W)

x 3,500 mm (H) - weight 71,790

kg), designed to house MV 10kV

Switchgear, a 10/0.42 kV Trans-

former, LV electrical switchgear,

Motor Control Centers, CDAS and

PMS cabinets and LV distribution

boards

> The HVAC module (dimensions =

8,000 mm (L) x 4,000 mm (W) x

3,500 mm (H) - weight 19,000 kg),

used for conditioning and pressur-

ization of the substation

HVAC SYSTEM

The HVAC system consists of 2 pack-

aged air conditioning units suitable

for overpressure, cooling and heat-

ing control during summer and winter

conditions. The 2 redundant automat-

ic units (1 duty, 1 standby) are capa-

ble also of automatic changeover with

programmable timetable and a manu-

al mode is available for maintenance.

The units are installed indoor on a

dedicated Module adjacent to the

substation building and provide sup-

ply and recirculate air flow from/to

the electrical room.

The transformer room is provided

with 2 exhaust fans (1 duty, 1 stand-

by) and fresh air intake. A temper-

ature transmitter will be monitoring

the room temperature which will be

kept within the design limits through

the duty fan started by the HVAC Lo-

cal Control Panel. When the fans are

not operating, a non-return damper

isolates the indoor from the outdoor.

A static electric heater in the trans-

former room keeps the room at +5°C

during winter, in case the transform-

er is not running.

The fresh air intake for the HVAC

units and the transformer room has

been installed on the roof of the

HVAC module and of the substa-

tion, and it has been realized with

materials, dimensions and weld-

ing length suitable to prevent any

gas from entering the substation.

The constant overpressure of the

building prevents entry of any airborne

contaminants that should be present

outdoor, and the filters included in the

HVAC packaged units ensure suitable

indoor ambient conditions.

FIRE & GAS SYSTEM

The Fire & Gas System has been de-

signed to prevent the presence of gas

and fire (by means of detectors) inside

the substation.

“The construction site manager has asked us to thank Skema for the way in which you have shipped and provided packing and as-sembly documentation for the Modular Sup-

port Frame. The site team were impressed with the individual marking of each piece of

the frame, identifying the container it is in and where it is located within it. The level

of detail Skema has provided has simplified the site assembly of the sub-frame and is

much appreciated.”

Procurement, Engineering & Construction

Skema acted as an EPC contractor for the solutions de-

livered, managing, coordinating and monitoring every

aspect of the project: detailed design, project manage-

ment, scheduling, procurement and expediting, QA/HSE

management, documentation, fabrication, all multidisci-

plinary installation activities (architectural, mechanical,

E&I, HVAC, etc.), and testing and pre-commissioning at

Skema’s facilities.

System by replacing 6 existing field

substations with 3 new substations.

SOLUTIONS DELIVERED

Skema was awarded the contract for

the design, manufacturing, inspec-

tion and testing of HV switchboards

and Remote Terminal Units (RTUs):

> 3 35 kV, 1250 A, gas insulated

switchboards (26 columns)

> 3 6 kV, 1250 A, 20 kA, 1 sec., air in-

sulated switchgear units (74 Columns)

> 4 redundant RTUs (10 columns)

and Electrical Control Systems -

based on PLC

> Switchgear continuous thermal

monitoring solution

> Arc fault protection system

INTEGRATED PROTECTION AND

CONTROL SYSTEM

The Integrated Protection and Con-

trol System (IPCS) for the project

was designed to monitor and con-

trol HV and LV switchgear located in-

side the different packaged Substa-

tions (North, South and West). Each

packaged substation is equipped

with a redundant Interface Con-

trol Unit (ICU) controlling 33 kV and

6.6 kV Switchgear with protocol IEC-

61850, Low Voltage Switchgear and

other utilities (HVAC, UPS, F&G) via

Modbus and hardwired interfaces.

A SCADA system is installed in the

Field Control Room to control and

supervise the electrical network.

Every substation is also equipped

with 4 video cameras and a vocal

communication system. This allows

to control the unattended substa-

tions (both through cabled alarms

and alarms generated by the vid-

eo cameras registering unexpect-

ed movements), and to commu-

nicate with the operators, giving

them directions. Data are record-

ed and are available in real time

for an Asset Lifet ime Manage-

ment System (maintenance and

energy ef f ic iency management

of the plant and its components).

SWITCHGEAR CONTINUOUS

THERMAL MONITORING SOLUTION

Skema provided TCO with Ex-

ertherm™, a continuous thermal mon-

itoring solution which allows to moni-

tor, in real time, the thermal health and

status of key bus bar joints and criti-

cal cable connections. This is achieved

by installing small plastic, non-con-

tact, non-powered, lifetime calibrat-

ed infrared and cable sensors within

the main electrical panels supplied.

This solution provides numerous tan-

gible benefits over traditional period-

ic scans, including greatly increased

levels of safety and integrity protec-

tion and reliability assurance through-

out the lifecycle of the electrical pan-

els. The integrity protection was further

enhanced by utilising a Load-Map™

software module which enables TCO to

dynamically adjust the thermal alarm

levels applicable to the load on the cir-

cuit being monitored, which provided

TCO with a level of integrity protec-

tion even at lower utilized load levels.

ARC FAULT PROTECTION SYSTEM

The 6 kV switchgear supplied for the

project has been equipped with a REA

arc fault protection system, which can

operate as a stand-alone device or in

combination with other modules, like

the REF relays. The REA arc fault pro-

tection system function is based on de-

tecting the intense light of an electric

arc, alone or on a detection of light and

simultaneous phase or neutral over-

current. On detection of an arc fault,

the REA protection system delivers

trip commands in less than 2.5 ms to

all circuit breakers that feed the fault

zone. Furthermore, the system oper-

ation indicators help localizing faults

by selectively guiding the maintenance

staff to the fault zone, that was identi-

fied by the arc fault protection system.

The REA module supplied for the project

features: two high-speed, galvanically

isolated, insulated gate bipolar tran-

sistor (IGBT) outputs (HSO1 and HSO2)

for CB tripping purposes; it offers one

heavy-duty relay output (TRIP3) to be

used, for example, as a circuit-breaker

failure protection (CBFP) output for an

upstream circuit-breaker, or as an alarm

output; it features an adjustable three-

phase overcurrent or two-phase and

neutral overcurrent condition monitor-

ing function, which enhances the relia-

bility of the arc fault detection by elim-

inating unwanted CB tripping caused

by light not related to any arc fault,

e.g. flash light used in photography.

LV SWITCHGEAR /

INTELLIGENT MCCs

The Low Voltage Switchgear and In-

telligent MCCs supplied for the pro-

ject are equipped with smart relays

that communicate with the ECMS us-

ing the IEC 61850 Protocol, which

affords a number of benefits, such as

interoperability between all the de-

vices in the substations regardless

of the manufacturer, and free allo-

cation of real functions on all levels,

allowing for the construction of flex-

ible and open, yet tailored, solutions

that are future-proofed to deal with

upcoming advances in communica-

tion technology.

The IEC 61850 standard provides

long-term validity through the di-

viding of applications and commu-

nications, and support throughout

the life cycle thanks to the intro-

duction of a standardized substa-

tion configuration language (SCL).

The result is an appreciable reduc-

tion in costs for the secondary system

over its life cycle. The LV bus duct is of

the compact type with copper lines; it

provides a complete solution for con-

nections between power stations and

transformers and the main panel board.

LV switchgear features:

> 13 Incomers REF 615

> 5 bus-tie REF 630

> 352 LTMR motor managers

MV SWITCHGEAR

The Medium Voltage switchgear for the

project is equipped with a metal enclo-

sure suitable for indoor installations.

Since the switchgear is highly modular,

the selection of components required

by any application is very simple.

The switchgear’s functional units are

guaranteed arc-proof in accordance

with IEC 62271-200 Standards, ap-

pendix AA, class A accessibility, crite-

ria 1 to 5. All the installation, operation

and maintenance operations can be

carried out from the front of the unit.

The switchgear and earthing switches

are operated from the front, with the

door closed. The communication pro-

tocol for the MV protection relays is IEC

61850, as it is for the LV switchgear.
