Abstract

This paper deals with a simulation investigation of a 500 kV transmission line design in Sarawak, Malaysia using Power Systems Computer Aided Design (PSCAD). Currently, the transmission system in Sarawak is mainly supplied by a 275 kV system covering the whole Sarawak state, starting from Miri district up to Kuching city - the so-called Sarawak Power Grid Backbone. Due to the rapid growth of industries and population in this state within the last ten years, it is necessary to improve the transmission system to become 500 kV. Therefore the investigation of transient overvoltage and overcurrent in a new 500 kV transmission line system when faults occur due to various faults on the line as well as a lightning strike, will be important in order to evaluate the system reliability. It was found that the lightning and three-phase faults cause the highest transient current surge on the line up to 9.06 and 9.27, respectively while the highest lightning transient overvoltage was observed at the receiving end of the line where it is near to Tada substation
