| 摘 要： | 为了同时提高本地振荡模式和区域振荡模式的阻尼特性,设计了一种双频段结构的电力系统稳定器.基于发电机六阶模型,把加速功率分解为PSS贡献的功率分量和不计PSS影响的分量,依据加速功率在复平面上的位置,确定了PSS的有效补偿相位区间.按照区域振荡和本地振荡模式的相位补偿要求,设计和分析了双频段PSS的结构.在一个八机系统下验证了所确定的补偿相位区间;配备双频段PSS后,机电振荡模式的阻尼特性提高较大.

| Abstract: | In order to simultaneously improve the damping performances of the local and inter-area modes,the dual-band power system stabilizer(DBPSS) is designed.Based on the sixth-order machine representation,the accelerating power is decompounded to two components: the power component directly contributed by the PSS and that without the PSS effect.From the position of the accelerating power in the complex panel,the effective PSS phase compensation range is determined.In accordance with the desired compensation phase... |
