Stabilization for Damping Multimachine Power System with Time-Varying Delays and Sector Saturating Actuator

الملخص EN

This paper studies the stabilization problem for damping multimachine power system with time-varying delays and sector saturating actuator.

The multivariable proportional plus derivative (PD) type stabilizer is designed by transforming the problem of PD controller design to that of state feedback stabilizer design for a system in descriptor form.

A new sufficient condition of closed-loop multimachine power system asymptomatic stability is derived based on the Lyapunov theory.

Computer simulation of a two-machine power system has verified the effectiveness and efficiency of the proposed approach.
