The hydraulic turbine governor system is one of the main equipment of a hydro power station and an indispensable component.The reliability and stability of the hydraulic system,served as the power source of the hydraulic turbine governor system,is directly related to the safety of the hydraulic turbine governor system.Frequent loading and unloading of the pressure oil pump can affect the reliability and safety of the hydraulic system.This paper describes the phenomenon of frequent loading and unloading of the pressure oil pump during actual operation,and provides a detailed analysis of the reasons for frequent loading and unloading of the pressure oil pump from two aspects:oil pressure device and electrical regulation.Based on the trend analysis of the unit's historical data,the status of the on-site pressure oil pump,and the touch screen data of the governor control cabinet,the reasons for frequent loading and unloading of the pressure oil pump were identified.Based on the fault location,a solution to the frequent loading and unloading of the pressure oil pump is proposed.
