In the industrial process plant, several power system analysis is need be done during planning stage or
during operation when remarkable change occurs in plant operating pattern. Motor starting study is also an integral
part of power system analysis. Several induction motor ranging from 0.5 kW to 4000 kW is used in process plant. To
check the operation feasibility without violating any parameter of motor or remaining power system, motor starting are
performed. Motor starting analysis is performed with big motor only. In this paper, Motor starting analysis of H.T
(6.6KV) motor of industrial plants is presented using Electrical Transient Analysis Program -7.5.5(ETAP). In industrial
plant, plant operating philosophy has decided by load flow and short circuit analysis. Here, power is produced by two
existing generators of 16.5 MW and one new generator of 11.8 MW is recently installed. To considering power import
location of all three generators, G2+G3 operating philosophy are selected and motor starting analysis is done with big
motor of 535kW. It is come to know that all parameter variation is within limit.
