摘　　要：针对华东电网的具体特点,将发电机组涉网参数大致分为一次调频、AGC、AVC和励磁系统等四类,并逐一对其评估指标进行阐述。结合华东电网现有EMS/SCADA及WAMAP系统,提出了发电机组涉网参数的在线评估方法,包括数据的采集处理和状态估计两部分。以发电机组一次调频参数为例,对该在线评估方法进行了具体说明。According to the practical condition of East China grid, generator grid-related parameters are classified intc four types： primary frequency control parameters, AGC parameters, AVC parameters and excitation system parameters, whose evaluation indicators are enumerated respectively. In combination with the current EMS/SCADA and WAMAP system, this research presents the online evaluation method for generator grid-related parameters, whictl covers data collection and processing and state estimation. Finally, generator primary frequency control parameters are studied as an example and its online evaluation method is elaborated.
