| Abstract: | The governor of a hydropower station adopts the SAFR-2000H (Nan Rui brand) hydraulic turbine governor, the guide vane and the blades are mainly equipped with GE company FC20000 and FC5000 main distributing valve respectively, and this type of equipment is widely used in the Kaplan turbine unit. This paper optimizes the functions of the power station governor system such as power down protection and choosing-two-from-three control logic, analyzes and summarizes the problems existing during the operation of the equipment, so that to better guide the operation duty work and improve the emergency management ability of the operators. |
