中文摘要	A single-slope closing law with a leading constant time delay was developed to improve the low efficiency of the traditional two-segment closing law used to stop the flow and the turbine in pumped storage stations after load rejection. The transient closing process in pumped storage stations for various rated heads was simulated with the time-delay closing law and two-segment closing laws. The time-delay closing law significantly reduces the maximum water hammer and turbine rotation speed and can be conveniently optimized since it has only two control variables. The time-delay segment provides simultaneous reduction of the rotational speed and the discharge of the reversible turbine after load rejection, which improves the efficiency of the optimized closing law.
