Abstract
The speed regulating system of hydraulic turbine is one of the core control systems in hvdroelectric generating set,and the mnain distributing valve is one of the key equipment of hydraulic system of governor.The amount of internal leakage of governor of Unit 5 during shut down period after minor repair in Longtan Hydropower Plant is found to increase significantly.For solving this problem,the structural features of main distributing valve of governor in Longtan Hydropower Plant are analyzed,and the change rule between piston position and leakage volume of main distributing valve is also analyzed.Finally,some suggestions to reduce the internal leakage are put forward.关键词
