Analysis of the Effect of Changes in RLC Load on Transient Stability of Electric Power Systems

Abstract

Today, in an effort to fulfill human electricity needs, a power system is needed to transmit electrical energy from generators to consumers. The occurrence of disturbances in the network can result in changes in system response for a certain time. Therefore, transient stability analysis is needed to determine the response that occurs in the network. Transient Stability is the ability of a power system to maintain synchronization after experiencing a sudden major disturbance. In this study, the researcher wanted to analyze the effect of the type of RLC load on the transient stability of a power system. Power flow and transient response of the grid network is expressed using ETAP software. The result, at the beginning generator is operated at stable condition, when the new load is connected to power system, generator output is changed depend the load types and there is oscillation in the generator output.
