Stability Analysis of Synchronous Motor by Lyapunov Functions and Dynamic Simulation

Lyapunov 함수를 이용한 동기전동기의 안전도 해석과 동특성 시뮬레이션

In the stability analysis of a synchronous motor, the considerations of the initial conditions, that is, field application points and the determination techniques of stability regions to assure stable operations over four quadrants are very important. In this paper, Lyapunov stability regions obtained from a newly proposed algorithm with Lyapunov function of simple type on the basis of numerical analysis method are shown to be true stability regions which can accurately pull in within 2 (rad) after field application.
