and reliability, and thanks to its ver-
satility, it can easily be adapted to suit
any plant configuration, electrical lay-
out or onsite installation requirement.
The wide range of sections and the
availability of different versions (af-
fording both front and rear access,
top or bottom cable entry) allow
Skema’s IN-CHARGE switchgear to
offer solutions with a view to sat-
isfying any set of requirements in
terms of installation and space.
Switching operations, as well as
access and routine maintenance,
can be carried out without com-
promising the safety of person-
nel and without any danger of ac-
cidental contact with live parts.

SYSTEM OVERVIEW

BUSBAR SYSTEM
11
MAIN BUSBARS
> Standard design ensures low probability of inter-
nal arc faults through the use of high-performance
busbar supports and oversized creepage/clearance
distances. Optional arc propagation barriers can be
installed between cubicles to limit the spread of
arcs in the unlikely event of an internal arc fault.
Busbar systems have been arc fault containment
tested in accordance with IEC 61641
> Available in ratings up to 5000 A, 100 kA RMS fault
withstand capability and 220 kA peak withstand ca-
pability
> All busbar are made from HDHC copper and can be
finished in plain copper, tin-plated, silver-plated,
nickel-plated or fully insulated
MCC RISER BUSBARS
> HDHC copper riser bars are round in cross section
for high through fault withstand capability and are
tin-plated for low contact resistance plus high me-
chanical endurance at the connection point of with-
drawable chassis
> An IP2X insulated barrier segregates the riser bar
from the MCC equipment bay and allows connec-
tion to the riser bar at 76 mm intervals
> Optional IP4X lockable automatic shutters can be
fitted for enhanced segregation and safety
> Standard riser bars have been arc fault containment
tested in accordance with IEC 61641 and are des-
ignated as an ‘arc proof zone’

IPCS SYSTEM
SKEMA’S INTEGRATED PROTECTION
AND CONTROL SYSTEM (IPCS) IS A
COMBINATION OF SOFTWARE AND
HARDWARE TO CONTROL AND SU-
PERVISE THE ELECTRICAL POWER
GENERATION AND THE DISTRIBUTION
PLANT. THE IPCS MONITORS AND
SUPERVISES THE STATUS OF EVERY
INCOMER AND FEEDER (FOR MV AND
LV SWITCHBOARDS) THROUGH THE
INTELLIGENT IPCD RELAYS. THE IPCD
SIGNALS ARE COLLECTED AND MAN-
AGED BY THE RTU.
The RTU, connected to the LMS/DMS
LAN and/or through the DCS LAN, ex-
changes information with the control
room. An operator can monitor and
supervise the system connecting with
a PC to the RTU or directly to LMS/
DMS Ethernet LAN.
Developed to comply with the most
stringent Oil & Gas Industry stand-
ards, Skema’s IPCS:
> Integrates the functionalities of
Shell DEP 33.67.01.31 (IMCS)
and DEP 33.64.10.32 (ENMCS)
> Controls all network components
at all voltage levels
> Interfaces with the process con-
trol system (DCS) in order to
match the electrical supply to the
processing requirements
> Compiles and analyzes data on
the performance and mainte-
nance of the electrical network
> Supplies data to higher-level sys-
tems to allow for the evaluation of
the overall plant key performance
indexes
> The integration of process and
electrical data permits to calcu-
late plant indexes and present a
plant dashboard related to avail-
ability, performance, profitability

THE OPERATOR INTERFACES
THE OPERATOR INTERFACES ARE IN-
STALLED IN DIFFERENT LOCATIONS
AROUND THE PLANT AND THEY
SERVE TO:
> Display live synopsis of switch-
boards and systems that are part
of the electrical network
> Display alarms and trends of real-
time and historic measurements
> Display IED details, allowing the
operator (where permitted) to
change the IED parameters
> Display sequence of events (SOE)
and disturbance recordings made
in case of trips
> Allow the operator (where per-
mitted) to change functional
parameters
> Allow the operation managers to
analyze performance, cost, relia-
bility and power quality
The Human-Machine Interfaces are
implemented across various levels:
> Operator control panel for intelli-
gent Power Motor Control Center
> Operator monitoring and control
interface for electrical cabins and
substations
> Operator workstations installed
in the Control Rooms to manage
all the functions of the electrical
network

THE INTERFACE CONTROL UNITS
The Interface Control Units (ICUs) are installed in each (and every) substations of the plant. They serve to:
> Communicate with IEDs and other systems (TG/EDG UCPs, UPS, HVAC) via IEC 61850, Modbus, IEC 101/104, DNP3,PROFIBUS, OPC, etc.
> Store and forward data in case of temporary network faults
> Allow for local connection of an operator workstation
> Perform substation automation (black-start, normal to emergency switchover, etc.) via communication and H/W’d IOs
> Operate as gateways for information and commands between the DCS and upper levels of IENMCS and IEDs
> Allow for intercommunication between devices and systems using different protocols
