Abstract

A method for controlling the state transition process of an oil pump in a hydraulic control system of a hydraulic turbine governor, more specifically, it is a three-state state of an oil pump in a hydraulic control system of a hydraulic turbine governor, namely standby state, idle state and loading state. The electrical control method aims to solve the problems of smooth transition of the state transition of the oil pump of the hydraulic control system of the turbine governor, and ensure the long-term safe and stable operation of the oil pump of the hydraulic control system of the governor. The hydraulic control system of the governor can provide long-term stable and The pressure oil source that meets the standards in various aspects such as pressure, temperature, and pressure oil particle content to operate the guide vane opening actuator.

Description

technical field [0001] The invention belongs to the technical field of the hydraulic control system of the governor of a hydraulic generator set, in particular to a method for controlling the state transition process of the oil pump of the hydraulic control system of the hydraulic turbine governor. Background technique [0002] The governor of the hydro-generator set adjusts the opening of the guide vane, the power and frequency of the unit, and the hydraulic control system of the governor needs to provide a long-term and stable pressure oil source that meets the standards in terms of pressure, temperature, and pressure oil particle content to operate the guide. Leaf opening actuator. However, there is no systematic and detailed disclosure of the structure of the hydraulic control system of the governor of the hydro-generator set and the control method of the control system for the state transition process of the oil pump of the hydraulic control system. Because the oil is ...
