摘　　要：为了抑制电力系统因负阻尼而产生的低频振荡 ,提高电力系统稳定性 ,设计了一种组合电力系统混合自适应稳定器 ( GPSS)。与传统设计不同 ,它包括几个自适应 GPSS,且这些稳定器同时又并联工作。稳定控制信号由各个单一的自适应 GPSS加权获得 ,同时又研究了加权系数的选择方法。理论分析和仿真结果都表明该方案对抑制电力系统低频振荡有显著效果 ,能提高电网运行质量 ,保障电网可靠、优质供电。A combination power system hybrid adaptive stabilizer GPSS is designed to suppress low frequency oscillation andto improve power system stability. The project is different from the traditional one. It includes a few adaptive stabilizers thatmerge to work. The stability control signal is obtained by weighting the signals of the few adaptive stabilizers. Theoreticalanalysis and simulation result show that the project is effective to suppress low frequency oscillation and ensures the reliabilityand quality of power supply system.
