1 INTRODUCTION
The intent of this study report is to carry out electrical power system analysis by performing protectioncoordination study of the electrical network under the scope of Borouge PO Flare Gas Recovery project (B3).
2 STUDY OBJECTIVEThe main objectives of protection coordination study are as follows:
To determine the characteristics, ratings, and settings of over current protective devices that minimizes plantoutages and interrupts short circuits as rapidly as possible.
To verify the existing protection device settings.
To verify the proper margin between protective devices in series to enable a back-up protection system.That is, upstream devices are on a standby basis to act expeditiously in case the immediate device nearer
to the fault location fails to operate.
Relay Coordination study is performed on the basis & recommendations of following international standards
IEEE Std 399-1997. (IEEE Recommended Practice for Industrial & Commercial PowerSystem Analysis)
IEEE Std 242-2001. (IEEE Recommended Practice for Protection and Coordination ofIndustrial and Commercial Power Systems)

5 BASIS & ASSUMPTIONS
The basis and assumptions are listed below
The protection data for motors i.e starting time, thermal withstand limits, thermal time constants etc arebased on technical data provided by vendor and assumptions are made where vendor data is pending.
Thermal overload settings of motors shall be performed at site during commissioning stage.
For simulation purposes, exact Relay/ETU model is used as available in standard ETAP device library. Incase of unavailability of particular model, nearest match having similar characteristics is used.
In this report, following switchgears of Unit 42 (PE5) and Unit 45 (PP4) are under observation as most ofthe loads under contractors scope are being fed from theses switchgears. However attached ETAP reportwill reflect the results of other switchgears as well.
42-ES-9001 (11 KV) 45-ES-9001 (11 KV) 42-ES-9011 (0.415 KV) 45-ES-9011 (0.415 KV)
6 NETWORK DESCRIPTION FOR STUDY
For the simulation, ETAP models have been updated as per the reference documents mentioned in section 3of this report. The Network Description for the study is as follows:
The main power sources for 11 KV switchgear 42-ES-9001 are 2 Nos. 33 KV feeders supplied byswitchgear 80-EE-1802 through 31.5 MVA, 33/11.5 KV transformers (42-EP-9011, 42-EP-9012).
2 Nos. 11 KV feeders (from switchgear 42-ES-9001) are stepped down by 2 Nos. 3.15 MVA, 11/0.433 KVtransformers (42-EP-9031, 42-EP-9032) to feed 0.415 KV switchgear 42-ES-9011.
The main power sources for 11 KV switchgear 45-ES-9001 are 2 Nos. 33 KV feeders supplied byswitchgear 80-EE-1803 through 31.5 MVA, 33/11.5 KV transformers (45-EP-9011, 45-EP-9012).
2 Nos. 11 KV feeders (from switchgear 45-ES-9001) are stepped down by 2 Nos. 2.5 MVA, 11/0.433 KVtransformers (45-EP-9031, 45-EP-9032) to feed 0.415 KV switchgear 45-ES-9011.
Following Generators are operating in Standby mode and considered OFF in the analysis.
42-EG-9201 42-EG-9001 45-EG-9001 45-EG-9201
7 MODEL SIMULATION CONDITIONS
Following are the basis of model simulation conditions.
Loads are categorized into Continuous, Intermittent and Stand by 100%, 50% & 0% loading respectively.
All Lump Loads are considered as Continuous and operating at 80% loading.
Loading Category is selected as Normal.
Primary tap positions are set at +2.5% of nominal voltage, for all transformers (for Unit 42 & 45).
33kV Grid bus is considered as slack/swing bus.
The by-pass switches for VFDs are closed to get maximum short circuit contribution from motors.
Maximum short circuit power from utility to switchgears of unit 42 and 45 is considered 1257 MVA (3-phase)as per etap model/etap report submitted by Company described in section 5 of this report.
Minimum short circuit power from utility to switchgears of unit 42 and 45 is considered 850 MVA (3-phase)as per etap model/etap report submitted by Company described in section 5 of this report.

12 CONCLUSION AND RECOMMENDATIONS
Relay coordination study has been performed after incorporating protection settings of existing system andproposed protection settings of newly added loads. The study reflects that both HV & LV electrical systemsare adequate and properly coordinated after the Borouge project load additions and no modification/updatein protection settings of existing system is required at this stage.
