Abstract

A major factor in the power system operation is the desire to maintain system security. System security involves a design to keep the system operating in the event of interference or failure. Interferences in electrical power systems are divided into generator, transmission, and load. Failure or interference of the transmission network results in a contingency of the transmission lines that can cause voltage in the bus and overload in the transmission lines, so it is very necessary to overcome the problem with a contingency analysis simulation to find solutions to problems caused by the disconnection of the transmission line. One of the contingency analysis methods is the 1P1Q (performance contingency index) method where the 1P1Q method lists the worst contingency impact on the electric power system to help engineers to solve problems and determine their next steps when contingencies occur. In the study, the Newton raphson’s methods were used to determine the power flow in electrical systems at normal conditions or contingency. Calculating the value of the contingency index in times of interference or failure using the 1P1Q method. The results show that the worst impact or highest-ranking performance index for the Madura 150 kV electric power system occurs in the infinity-base scenario where two lines are overloaded and exceed the maximum value limit of the transmission line power of the infinity-gilitimur channel of 157.5 MW with a maximum value limit transmission line of 92,359 MW and gilitimur-bangkalan of 149 MW with a maximum value limit of transmission line of 88,616 MW. So there is prevention with load shedding of 87,638 MVA with scenario 6 in table 4:24 of load shedding on the bus Sampang, Sumenep, Pamekasan because by shedding loads of 95,528 MVA the power flowing at infinity-gilitimur becomes 72.9 MW.
