A steady state contingency analysis for Sabah Electricity Sdn. Bhd. (SESB) System / Decimus Balangkit

A steady state contingency analysis is a method by which we can predict steady state transmission line loadings in a power system following the switching of lines or generators or buses. The steady state contingency analysis is conducted on system peak load. The contingencies study in Sabah Electricity Sdn. Bhd. grid interconnection systems is for the preparation to protect any incidents may occur that is not foreseeable. The steady state simulations of the Sabah Electricity Sdn. Bhd. system is carry out using powerworld simulator. The simulation focuses on single transmission and double transmission lines contingencies. This result leads to the contingency ranking by referring to the list of contingencies at each transmission line according to the severity. The ranking shows that the single contingency outage of 66 kV line between Tanjung Lipat and Inanam is the worst case making the heaviest line with 153% overloading
