摘　　要：背靠背起动方式作为抽水蓄能电站起动的备用手段,对电站的稳定运行具有重要作用。利用实际抽蓄电站参数建立起动过程水机电耦合仿真模型,探究调速器参数、同期装置参数对起动过程的影响,发现调速器参数设置不当极易引起超调,尤其比例调节参数K_(p)的影响最大;同期装置参数中调速信号脉宽对起动是否成功起决定性作用,选择合适的脉冲宽度、调节周期决定了起动时间的长短。The back-to-back start-up mode, as a standby means for the start-up of pumped storage power station, plays an important role in the stable operation of the power station. In this paper, the hydro-electromechanical coupling simulation model of starting process is established by using the actual pumped storage power station parameters, and the impact of governor parameters and synchronization device parameters on the starting process is explored. It finds out that inappropriate parameter setting is prone to cause the overshoot of governor, especially for K_(p). In the same time, the pulse width of the timing signal in the device parameters plays a decisive role in the success of starting. Choosing the appropriate pulse width and adjusting cycle determines the starting time.
