Influence of Field Mutual Leakage Reactance in Generator Model on Dynamic Behavior

—Study on Sudden Short Circuit, Load Rejection and PSS Eect—

Abstract

This paper describes the effect of mutual leakage reactance in rotor circuit (Canay reactance) on analysis of generator transient and dynamic behavior. The authors derived a detailed equivalent circuit model for 48P-15.75MVA generator, and analyzed sudden short circuit and load rejection phenomena of the generator by simulations using the electromagnetic transients program (ATP-EMTP), and compared the results with the experimental data. In addition to these analyses, the influence of mutual leakage reactance on analysis of power system dynamic stability was investigated.
