Evaluating the unbalances in sarawak transmission lines using PSCAD/EMTDC
This paper describes the electromagnetic transient study carried out to calculate the degree of unbalance in existing transmission network in Sarawak. It first discusses the modelling of the transmission grid in PSCAD/EMTDC and the verification of the simulation model against real-time recordings. The paper then provides estimation on the current unbalances in individual circuit and paralleled circuits due to the net through system unbalance and circulating currents based on the positive, negative and zero sequence currents obtained in the simulation. Based on simulation, different phasing arrangements are also assessed to reduce the amount of line unbalance.
