摘要

为定量分析采用全局信号控制的电力系统稳定器（PSS）的时滞稳定性问题，利用扫频法对计及广域阻尼控制的2级PSS控制策略和PSS辅助区间阻尼控制进行数学建模，并计算出各自的时滞稳定极限，进而定量分析了时滞PSS系统的控制性能。算例验证了该方法的有效性和实用性。

Abstract

The aim of this paper is to provide a quantitative stability analysis of a time-delay power system stabilizer（PSS） system with centralized wide-area control using additional global signals. Frequency-sweeping（FS） test is proposed to compute the delay margin of two-level PSS design and the system with additional inter-area damping， and the control performance is further estimated quantitatively. Simulation results verify the validity and pragmatism of the proposed method.
