PSSwindup limitersSmall-signal stability analysis in a power system uses a linearized approximation of its nonlinear model to analyze its behavior when subjected to small perturbations. In this approach, there is an implicit assumption that the perturbations are small enough so the imprecisions of ...
(5)正常只投电压调节器自动,无功控制器“VARCONTROLLER”只有在发电机需要固定无功时才投用。 (6)电力系统稳定器PSS当有功负荷超过20%达6S时可根据调度命令投入。 (7)励磁调节柜正常停用期间可以不停用外部电源,如果检修有工作,必须将外部电源停电。 答案解析 略 真诚赞赏,手留余香 小额打赏 169人已赞赏...
