Fault Diagnosis Oil Pressure Intelligent Control System and Diagnosis Method of Hydropower Station Governor

Abstract

The present invention provides a fault diagnosis hydraulic intelligent control system for the governor of a hydropower station, including: a monitoring center, a governor oil pressure intelligent control device, a display, a fault diagnosis module, an oil pump motor unit, an oil pump motor unloading solenoid valve group, An oil tank air supply solenoid valve, an oil tank pressure switch, an oil tank oil level switch, an oil return tank oil level switch, an oil tank pressure transmitter, an oil tank oil level transmitter, and an oil return tank oil level transmitter; and a The diagnosis method based on the hydraulic intelligent control system of the governor of the hydropower station includes an internal diagnosis method and an external diagnosis method; the present invention solves the existing problems of the prior art, which are easy to fail, difficult to maintain, and have low practicability and failure to monitor faults caused by complex structures occurrence, a large amount of manpower is required for troubleshooting and maintenance, and problems such as the inability to display the operating status of the system in real time and query historical operating data.

Description

technical field [0001] The invention belongs to the technical field of hydropower stations, and in particular relates to a hydraulic intelligent control system and a diagnosis method for fault diagnosis of governors of hydropower stations. Background technique [0002] The oil pressure intelligent control system of the governor of the hydropower station is an important part of the auxiliary equipment of the hydropower station. It is very important in the control system of a hydropower station because it is the prerequisite for the normal operation of the turbine and even the normal operation of the turbine and generator to generate electricity. [0003] Deep image processing (image processing) is a technology that uses computers to analyze images to achieve the desired results. Also known as image processing. Image processing generally refers to digital image processing. A digital image refers to a large two-dimensional array obtained by shooting with industrial cameras, ...
