Development of Electrical Transient Modeling and Simulation for Electric Distribution Systems

This paper describes analysis, modeling and simulation of electrical transients for electric distribution systems. The proposed modeling is based on simple numerical integration called Trapezoidal integration which is able to efficiently handle some sophisticated calculation. In this paper, an abnormal condition is situated by simply adding a fault resistance at the fault location. With the proposed methods, transient behaviors of voltages and currents can be analyzed and evaluated. To demonstrate the use of the proposed simulation, a 4-bus power system was used for test.
