摘要
对常见的PSS输入信号作了概括，分析了导致电力系统低频振荡的原因。对以△ω和△Pc同时为输入信号的PSS作了研究，提出了电力系统稳定器设计的一种新思路。仿真结果表明，以这种新思路为指导设计的电力系统稳定器有良好的性能。
The input signals of Power System Stabilizer(PSS) widely utilized are summarized. A new idea in designing PSS with two inputs Δω and ΔP_e is put forward. It is illustrated by simulation result that the PSS based on this designing idea has excellent performance.
