Abstract For the problem Starting current in power grid voltage fluctuation and easy to cause damage of motor and pump when Pumped storage pump in power station is started directly, method with using static frequency converter (SFC) reduce the start motor impulse current is developed; in the design of SFC ,a variety of electrical protection measures are equipped, external can take is used ,to ensure the SFC inverter can reliably work in low voltage. Through to the SFC converter valve factory test, to verify the control equipment function and the correctness of algorithm, and the reliability of the whole system design, security and stability, and to provide a feasible method that Ensure the normal order of the pumped storage power station motor is up and running.
