Abstract

A method for controlling the operating state of a hydraulic system of a hydraulic turbine governor, which is an electrical control method for oil pump start-stop and loading and unloading control under the operating conditions of the hydraulic control system of a hydraulic turbine governor. , Control the start, stop and loading and unloading of the oil pump of the hydraulic control system of the turbine governor, and maintain the long-term stability of the hydraulic control system pressure of the turbine governor near the rated pressure; The hydraulic control system of the device can provide a long-term and stable pressure oil source that meets the standards in various aspects such as pressure to operate the guide vane opening actuator.

Description

technical field [0001] The invention relates to the technical field of hydraulic control of a governor of a hydro-generator set, in particular to a method for controlling the operating state of a hydraulic system of a governor of a hydro-turbine. 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 control method for the pressure maintenance equipment such as the oil pump motor under the running state of the electric control system of the governor of the hydro-generator set. Because the oil is not easily compressible, in order to ensure that the oil has a relatively stable pres...
