Hydraulic power station governor oil pressure intelligent control system capable of diagnosing faults and diagnosing method

Abstract

The invention provides a hydraulic power station governor oil pressure intelligent control system capable of diagnosing faults. The intelligent control system comprises a monitoring center, a governoroil pressure intelligent control device, a displayer, a fault diagnosis module, an oil pump motor set, an oil pump motor unloading electromagnetic valve set, an oil tank gas supplementing electromagnetic 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. The invention further provides a diagnosing method based on the hydraulic power station governor oil pressure intelligent control system. The diagnosing method comprises an internal diagnosing method and an external diagnosing method. The hydraulic power station governor oil pressure intelligent control system and the diagnosing method solve the problems that in the prior art, faults are prone to occurring, maintenance is difficult, the structure is complex, and consequently practicability is low, faults cannot be monitored, trouble shooting and repairing require a largequantity of labor, the operation condition of the system cannot be displayed in real time, and historical operation data cannot be inquired.

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 diagnostic 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 analyzes images with computers to achieve 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, video...
