However, the impact of time delays 关键词：电力系统；广域控制；广域测量系统；时滞；柔性 introduced by remote signals’ transmission and processing in 交流输电系统；线性矩阵不等式 WAMS has to be considered, and the closed-loop power 0 引言 systems have to be modeled as time-delay differential dynamic systems. This paper investigates the wide-area FACTS 广域测量系统(WAMS) 已在包括我国电网在内 controller design problem of power system in the presence of [1-3] 的许多国家电网中得到了应用 ，它能够对电网运 output feedback delays in WAMS. In order to eliminate the 行的诸多关键变量 （如电压、功角，频率等）进行 negative effects of time delays, a general approach based on linear matrix inequality (LMI) technique, genetic algorithm and 同步采集和 控，为电力系统分析及
