摘　　要：抽水蓄能机组在水泵运行方式下,同步发电机作为同步电动机在变频控制下起动主要有3个难点:发电机转子初始相位及低频运行时转子相位检测;根据转子所在的位置给相应绕组施加电流,并以正确方向旋转;发电机在低频运行阶段的断流换相问题。经过试验,找到了解决上述问题的方法,且控制简单可靠。There were three main problems when the synchronous motor starting through the static frequency convertor of the pumped-storage unit under pumping oper- ation mode： the initial phase position of the generator rotor, supplying voltage level to the relative winding based upon the rotor position and commutation problem in the condition of intermittent current under the low frequency. The simple but reliable solving problems were found through experiments.
