Abstract. Electric power transmission system must operate reliably and continuously, but in fact there are many disturbance that affect the reliability and stability of the power system. This study aims to determine the weak elements of power system when release of components occur. This study uses simulation with Newton Raphson power flow method for contingency analysis. The study is located in South Bandung electric power system with voltage of 150 kV. In this study, the object of contingency analysis is IBT-II 500/150 KV at peak periods load in 2013 to evaluate the system reliability when release of the Inter bus Transformer (IBT). Selection of the component is based that IBT is the most important component in the power supply that should be maintain continuously. The results of the study and analysis show that in the event of contingency almost all bus voltage has decreased below the limit allowable voltage and IBT-I get overloaded, then the maneuver is performed according to the procedures of specified load. The results of this study can be use as a reference for the electric power operating system which has conditions similar to the simulated cases.

Reliable and secure operation of bulk power transmission system components is an important aspect of electric power engineering. Component failures in a transmission network can lead to serious consequences and impact system reliability. The operational health of the transmission assets plays a crucial role in determining the reliability of an electric grid. To achieve this goal, scheduled maintenance of bulk power system components is an important activity to secure the transmission system against unanticipated events. This thesis identifies critical transmission elements in a 500 kV transmission network utilizing a ranking strategy. The impact of the failure of transmission assets operated by a major utility company in the Southwest United States on its power system network is studied. A methodology is used to quantify the impact and subsequently rank transmission assets in decreasing order of their criticality. The analysis is carried out on the power system network using a node breaker model and steady state analysis. The light load case of spring 2019, peak load case of summer 2023 and two intermediate load cases have been considered for the ranking. The contingency simulations and power flow studies have been carried out using a commercial power flow study software package, Positive Sequence Load Flow (PSLF). The results obtained from PSLF are analyzed using Matlab to obtain the desired ranking. The ranked list of transmission assets will enable asset managers to identify the assets that have the most significant impact on the overall power system network performance. Therefore, investment and maintenance decisions can be made effectively. A conclusion along with a recommendation for future work is also provided in the thesis.
