摘要
根据二滩水电站发电机定子绕组的分布特点,对发电机的内部故障进行了分析,并结合CT的配置情况,提出了发电机横差保护的配置方案。通过对改造后的横差保护原理分析,对发电机横差保护的定值进行了整定,并用不同工况下的实测数据进行校正,最后得出横差保护配置和定值整定的一些注意事项。
The internal faults on stator winding of generator are analyzed according to stator winding distribution characteristics of Ertan Hydroelectric Power Station, and the configuration scheme of transverse differential protection is proposed based on CT configuration. The setting value of transverse differential protection is calculated by analyzing the principle of transverse differential protection, and it is corrected by using measured data at different operation conditions. Some considerations on generator＇s transverse differential protection configuration and setting value calculation are also suggested.
