摘　　要：要确保发电机组暂态稳定性良好,就需要重视电气制动装置,常规的电气制动装置是通过电阻消耗转子动能,来改善发电机组的暂态稳定性,这种电气制动装置为耗能型装置。为了实现发电机组暂态稳定性的最大优化,拟采用将转子动能通过电容储存,等并网恢复后再释放能量的电气制动方式,即储能型制动装置。通过分析储能型电气制动装置具体的暂态稳定性优化效果以及功率补偿功能,明确储能型电气制动装置与发电机的综合协调控制成效。In order to ensure the good transient stability of the generator set,we need to pay attention to the electric braking device.The conventional electric braking device is to improve the transient stability of the generator set by consuming the kinetic energy of the rotor through resistance,which is an energy consuming device.In order to achieve the maximum optimization of transient stability of the generator unit,the electric braking mode is proposed to store the kinetic energy of the rotor through the capacitor and release the energy after the grid connection is restored,that is,the energy storage braking device.By analyzing the specific transient stability optimization effect and power compensation function of the energy storage electric braking device,the comprehensive coordinated control effect of the energy storage electric braking device and the generator is clear.
