| Abstract: | The head cover drainage control circuit of axial flow adjustable blade water turbines in Qingxi Hydropower Plant used to break down, which was not only a nut for the power plant but also a problem demanding prompt solution of domestic similar units. Consequently, a modification was made. The main causes of the fault were found through fault statistical analysis, and the conventional control circuit replaced by programmable controller. No failure has occurred on the pump control circuit since the modification. |
