Introduction
Project: 1x 15 MW Captive Power Plant at Janki Corpn Ltd,Bellary
Owner:JCL Janki Corpn Ltd Steel Divn,Madpiya Chordia,Chittor Road,Bhilwara-311001,Rajasthan
ElectricalDistribution System11 kV Power Generation,6.6 kV Station Service and 6.6 kV for Unit Auxiliarysystem 110 kV for Transmission and Distribution and distribution at 0.415 kV
Power System DataMax Source Fault level(assumed)
5000 MVA sec at 110 kV
Min Source Fault level (assumed) 10000 MVA sec at 400 kV
Tools used: Paladin Design Base 5- an Electrical Design softwareProtection Coordination
The short circuit currents at various busbars are calculated based on the aboveassumptions. Calculated Short circuit currents are shown in the SLD.Selectivity of relays and circuit breakers were worked out based on the cablesize and flow of short circuit currents.Time current characterstic curves are generated for every path and verified .
ConclusionSettings for each device,short circuit currents at every busbars,detailedcalculations for the settings are given in the following pages. While doing thisexercise certain discrepencies were noticed and these are brought outseperately under heading 'Comments and Observations'.
Executive Summary
Settings for each device,short circuit currents at every busbars,detailedcalculations for the settings are given in the following pages. While doing thisexercise certain discrepencies were noticed and these are brought outseperately under heading 'Comments and Observations'.

Observations and Comments:
1) The Single line diagram furnished by the customer has got many discrepencies with actuals at
site,especially the CT details furnished in the drawing are not matching.The customer has to prepare as fitted
drawing for their future reference.2) The Second Turbo Generator 3 MW set has got CT ratio of 300/1.However it is noticed that the incomer
in the 11 kV switch board from this Generator has got CT of 1250/1.We have given the settings assuming this
CT will be matched with Generator CTs3) There is one overall Differential Protection Relay, CTs from 15 MW Generator,HV side and LV side of
Generator Transformer connected.This relay operation will be in order when only one Generator 15 MW is in
operation.If the 3 MW set is in operation , this differential relay will pick up and trip the Breaker.Modification
of the circuitary is required.
