working closely with its Uralsk-based

partner in kazakhstan, skema was re-

sponsible for the provision of the pmcc

switchboards for the atyrau Refinery.

the project proved to be a success

thanks both to the experience ac-

quired by skema in the kazakh market

since 1998, which it was able to

leverage fully, and to the important

technology transfer program es-

tablished with its kazakh partner.

the commissioning was carried out

by local electrical engineers, un-

der the supervision of skema’s site

services manager.

skema’s supply included:

lv swiTchgeAR /

inTelligenT Mccs

the low voltage switchgear and

Intelligent mccs supplied for the

project are equipped with smart

relays that communicate with the

Ecms using the IEc 61850 protocol,

which affords a number of benefits,

such as interoperability between all

the devices in the substations re-

gardless of the manufacturer, and

free allocation of real functions on

all levels, allowing for the construc-

tion of flexible and open, yet tailored,

solutions that are future-proofed to

deal with upcoming advances in

communication 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

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.

skeMA MoToR conTRol And

MAnAgeMenT sYsTeM (McMs)

the motor control and manage-

ment system (mcms) developed for

the platforms integrates the intelli-

gent motor control centers made by

skema with the process control sys-

tem (pcs), the power management

system (pms) and the distribution

management system (dms), and en-

ables an integrated and safe man-

agement of all the electrical users.

the integration is achieved thanks

to the communication capabili-

ties of the dcUs which operate as

gateways between the upstream

pcs/pms/dms and the IEds with-

in the downstream switchgear.

the dcUs allow concurrent commu-

nication via redundant modubus-RtU

and opc between the different sys-

tems. such integration completely ex-

ploits the capabilities of the 400 IEds

(supplied by different manufacturers)

which measure, protect and control

all the users connected to the mcms.

Importantly, the mcms not only helps

the operator to control the users, but

is of great significance to the electrical

engineer in verifying the performances

of the electrical networks by means of

continuous monitoring of the param-

eters set in the IEds with special at-

tention to those which influence the

reliability/maintenance of the plant.

the mcms records the running hours,

the number of operations of each

feeder circuit and analyzes the most

frequent causes of tripping/alarms,

so that the engineer can plan proac-

tive counter measures to avoid future

plant problems which may cause eco-

nomic losses and, in the worst cas-

es, safety risks to the plant/personnel.

this type of intelligent reporting is piv-

otal in ensuring a proactive and cost ef-

fective maintenance regime of the plant.

all the dcUs components are dual

redundant and can survive any in-

dividual component failure. the se-

rial links communicating with the

downstream IEds via modbus-RtU

ring (motor managers, measuring

devices and protection relays) can

survive a fault where the serial ca-

ble is broken between two devices.

system response times are of ut-

most importance, the mcms is de-

signed for ultimate performance. a

command received from the pcs is

actuated by the IEds in less than

100 ms and the change of status

is available to the pcs in less than

1 second. these performances are

achieved while the dcUs communi-

cate concurrently with the pcs via

modbus-tcp, with the pms via mod-

bus-RtU and with the dms via opc.

foR excellence

on 22nd February 2012 skema was

invited to attend the jasmine supplier

awards for Excellence ceremony, as

a Nominee among the 15 excellent

suppliers (out of the over 160 suppli-

ers for the project) to the conocophil-

lips jasmine development project.

conocophillips launched the jasmine

supplier awards for Excellence pro-

gramme in january 2011, with the aim

to develop and recognize the project’s

principal suppliers through setting key

metrics, evaluating business perform-

ance, identifying gaps and opportu-

nities for improvement and recog-

nizing and rewarding excellence.

being one of the best suppliers to

conocophillips is a matter of pride

for skema, whose nomination in the

“planning and delivery” category

was motivated by conocophillips

as follows: “skema was a bright

star in jasmine’s electrical success.

their embrace of sap’s ERp prior to

jasmine was evident in their planning,

scheduling, detailed design, material

availability, along with the lv switch-

gear’s and mcc’s fabrication.”

“Many thanks for all your good efforts in making this happen.

Skema’s proactive approach towards resolving and expediting really helps

us and is very much appreciated by the Project.”

key features of skema’s Intelligent

motor control centers are its draw-

ers and incomers equipped with

microprocessor relays. In addi-

tion skema developed the Electri-

cal control system for the karach-

aganak project in kpc and Unit 2.

Each station is equipped with a Re-

mote terminal Unit (RtU), which col-

lects data from the switchboards

and interfaces with dms and dcs.

the accumulated data is then made

available for visualization on Ews

and on plan dms. skema has sup-

plied a total of nine packaged sub-

stations for Early works, two 6 kv

packaged substations for Unit 3, a

packaged substation for a Flash gas

compressor control Room, and a se-

ries of eight packaged substations

for a waste management complex.

as for the switchgear, skema supplied

the karachaganak project alone with

some 123 mv panels, 622 lv panels,

38 RtUs, 24 110v dc panels, more

than 250 relays, and 2,559 drawers.

kARAchAgAnAk / kazakhstaN

“Skema provided an excellent serv-ice in assisting with the commission-

ing of their supplied equipment on site here in Karachaganak. I can say that the work completed was carried

out in a timely manner, to high stand-ards, often in arduous conditions.

The working relationship that devel-oped with Skema personnel was ex-

cellent, as they were always pre-pared to go the extra mile to resolve any anomaly that arose on site and meet the end user’s expectations.”

inTegRATed pRoTecTion And conTRol sYsTeM (Ipcs)

the Ipcs is based on IcUs (Integrat-

ed control Units) located in each

substation, which communicate with

the motor starters and the protec-

tion relays, making all the information

available for the operator worksta-

tions and the redundant servers in-

stalled in the main control Room, and

operate 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

assists 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.

“I appreciate all aspects of Ske-ma’s performance, and in particu-

lar: your team’s efforts in turning around accurate engineering docu-mentation in a timely fashion, Ske-ma’s proactiveness in dealing with third parties, Skema’s flexible and

adaptable manufacturing approach to accommodate EBCL’s construc-

tion priorities, and Skema’s swift clear communication with the OGD

III Project team and the overall quality of Skema’s work product. Skema’s approach to the OGD III

project has been most profession-al at all times and its high caliber

performance has been noted.”

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 gate-

way to the dcs (distributed control

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.

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 control

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 vo-

ca l c ommun i ca t i o n s y s t em .

this allows to control the unat-

tended substations (both through

cabled alarms and alarms gen-

erated by the video cameras reg-

istering unexpected movements),

and to communicate with the op-

erators, giving them directions.

data are recorded and are availa-

ble in real time for an asset lifetime

management system (maintenance

and energy efficiency management

of the plant and its components).

swiTchgeAR conTinUoUs TheR-

MAl MoniToRing solUTion

skema provided tco with Exer-

therm™, a continuous thermal moni-

toring solution which allows to moni-

tor, in real time, the thermal health and

status of key bus bar joints and critical

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 periodic

scans, including greatly increased lev-

els of safety and integrity protection

and reliability assurance throughout

the lifecycle of the electrical panels.

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

circuit being monitored, which provid-

ed 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 opera-

tion 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, gal-

vanically isolated, insulated gate bi-

polar transistor (Igbt) outputs (hso1

and hso2) for cb tripping purpos-

es; it offers one heavy-duty relay out-

put (tRIp3) to be used, for example,

as a circuit-breaker failure protection

(cbFp) output for an upstream cir-

cuit-breaker, or as an alarm output;

it features an adjustable three-phase

overcurrent or two-phase and neu-

tral overcurrent condition monitoring

function, which enhances the reliabil-

ity 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.

“Finally a word of thanks to you and your team for an excellent performance and outstanding custom-

er service on our project.”
