Embodiment

[0064] The method of the invention is applied to the working condition rotation control of the hydraulic control system of the governor of a power station. The system is designed with 4 fixed frequency motor oil pumps, the rated system pressure is 6.3Mpa, and the system shutdown maintenance pressure is 5.9Mpa. The method of the present invention will be described in detail below in conjunction with this embodiment.

[0065] By adopting the method of the present invention, the detailed steps of the working condition rotation control method of the hydraulic control system of the turbine governor of a power station are as follows:

[0066] 1. Initialize the controller of the governor hydraulic control system and go to step 2.

[0067] 2. The hydraulic control system enters the shutdown standby state and goes to step 3.

[0068] 3. The controller of the hydraulic control system of the governor detects whether it has received the command to start the hydraulic control system from...

Abstract

The invention discloses a method for controlling the rotation of working conditions of the hydraulic control system of a hydraulic turbine governor, which is a four working conditions of the hydraulic maintenance system of a hydraulic turbine governor, namely, the shutdown standby working condition, the starting process working condition, and the running working condition The electrical control method of switching between the working conditions of the turbine governor and the shutdown process in turn aims to solve the problems of smooth transition and conversion between the four working conditions of the hydraulic pressure maintenance system of the turbine governor, and ensure that the hydraulic maintenance system of the governor provides long-term stability and The pressure oil source that meets the standards in various aspects such as pressure, temperature, and pressure oil particle content is used 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 hydro-generator set, and in particular relates to a working condition rotation control method of the hydraulic control system of the 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. In the prior art, the research on the hydraulic control system of the governor of the hydro-generator set mostly focuses on the structural design and control performance of the guide vane operating actuators such as electro-hydraulic conversion and hydraulic amplification. There are few researches on working c...
