Estimation of impedance parameters and evaluation of synchronous machine using Electrical Design and Simulation Analysis (EDSA)

This paper presents a refined approach to obtain the impedance parameters of synchronous machine equivalent circuits from standstill DC decay tests. Estimating parameters of high power synchronous machines from steady state or transient AC operational tests requires a great deal of electrical power. The proposed method is simple, safe and less expensive than other methods. This testing technique reduces the required power and minimizes the testing time. A novel computer system EDSA (Electrical Design Simulation Analysis) tool for the parameter estimation of synchronous machine is presented. It uses state of the art information technology software. The tool allows the electrical engineers to obtain the electrical parameters of a synchronous machine.
