摘要
针对G60型发电机保护在实际运用中发现存在的设计缺陷,导致机组正常停机时,逆功率保护拒动作。停机后用ONLLY-6108G继电保护校验仪实际加电流对保护装置进行传动试验同时对装置电源卡件的输出电压进行监视测量最终查找出保护拒动的真实原因,并就导致该保护装置拒动因素进行分析,总结经验教训并提出相应的改进及预防措施。
In view of the design flaw of G60 generator protection in the actual utilization when the unit engine is normal off, the reverse power protection resists movement.After the engine off, it carries on at the same time the transmission experiment with the relay protection verification meter actual adding current to the protective device to make the surveillance survey to the installment power source card output voltage finally to search the real reason which the protection resists to move. And causes of this protective device to resist to move are analyzed. The experience lesson is summarized and the corresponding improvement and the preventive measure are proposed.
