Abstract

One of the difficult problems in large pumped storage unit´ localization process is inhibited “S” shape characteristic impact. This paper puts forward a kind of switching controller: dual differential channel control algorithm (PID²), the background is the conventional PID control algorithm to inhibition of pumped storage unit “S” shape characteristics. Compared with the conventional PID algorithm simulation, and the field application test in Anhui Xiangshuijian pumped storage power station show that, the proposed algorithm can effectively inhibit the pumped storage unit “S” shape characteristics author.
