介绍了2001年中国电力系统主设备继电保护动作情况,分别对100 MW及以上发电机保护(含发电机变压器组)、50 Mvar及以上调相机保护、220 kV及以上电压变压器保护、母线保护和高压电抗器保护装置的运行情况进行分析,并结合事故实例,详细论述了由于运行维护管理方面、制造部门或其他部门责任造成保护不正确动作的原因.并提出针对问题采取措施,提高保护运行水平.

Operating situation of China's main equipment protections in 2001

The operating situation of China's main equipment protections in2001is introduced,including100MW and above generato r protection(generator and transformer set),50Mvar and above phase-angle regulator protection,220kV and above transformer and bus protection,and high voltage reactor protection.In order to improve the operation of protections,with the incident examples,the improper protection performances caused by the responsibilities of operating management ,manu-facture and other departments are analyzed and the countermeasures are proposed.
