1 INTRODUCTION The intent of this study report is to carry out electrical power system analysis by performing protection coordination study of the electrical network under the scope of Borouge PO Flare Gas Recovery project (B3). 2 STUDY OBJECTIVE The main objectives of protection coordination study are as follows:   

To determine the characteristics, ratings, and settings of over current protective devices that minimizes plant outages 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 Power System Analysis) IEEE Std 242-2001. (IEEE Recommended Practice for Protection and Coordination of Industrial and Commercial Power Systems)

4 ETAP MODEL As per Descon / Contractor scope (DOC: Electrical System Description and Scope Definition for EPC Package) in Borouge 3 expansion project, Descon has to analyze the impact of newly added loads (which are in Descon scope, DOC: Electrical Load Summary B3) on the electrical network of B3 by performing the protection coordination study. The details of ETAP model provided by Company are as follows: Name: ETAP-3583-PO This contains the following switchgears with associated electrical equipment (Motors, Transformers, and Cables etc). 80-ES-1802 (33 KV) 41-ES-9203 (3.3 KV) 42-ES-9213 (0.415 KV) 42-ES-9201 (11 KV) 42-ES-9203 (3.3 KV) 42-ES-9212 (0.415 KV) 44-ES-9202 (3.3 KV) 44-ES-9212 (0.415 KV) 45-ES-9202 (3.3 KV)

41-ES-9001 (11 KV) 41-ES-9011 (0.415) 41-ES-9212 (0.415 KV) 42-ES-9001 (11 KV) 42-ES-9011 (0.415 KV) 44-ES-9001 (11 KV) 44-ES-9011 (0.415 KV) 45-ES-9001 (11 KV) 45-ES-9011 (0.415 KV)

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 are based 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. In case 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 of the loads under contractor’s scope are being fed from theses switchgears. However attached ETAP report will 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 3 of 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 by switchgear 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 KV transformers (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 by switchgear 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 KV transformers (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

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 and proposed protection settings of newly added loads. The study reflects that both HV & LV electrical systems are adequate and properly coordinated after the Borouge project load additions and no modification/update in protection settings of existing system is required at this stage.
