Transient Analysis of a Standard IEEE-9 Bus Power System Using Power World Simulator

Abstract

Study of transient analysis and its behavior is very important aspect for power system planning and its design for reliable operation. The paper's main objective is to analyze the system for different fault conditions such as three phase balanced, line to ground, line to line, and double line to ground fault. As a test system, the standard IEEE 9 bus system is selected because of its simplicity of smart grid which facilitates to study all the concepts. Due to abnormal conditions (fault conditions), power system may become unstable thereby causing severe damage to protection equipment. Therefore, to ensure reliable power system operation, fault analysis study is necessary. Here, power world simulator software is used to analyze system. The pre-fault conditions are determined by the Newton Raphson method of load flow analysis. In this paper, the effects of generator outage and bus outage are studied and how the system retains its stability after outage has been discussed. Further, transient analysis of power system network will facilitate the design of better smart grid.
