On-line state monitoring control method and monitoring system for hydropower station sluice gate

Abstract

The invention discloses an on-line state monitoring control method and a monitoring system for a hydropower station sluice gate. The method comprises the following steps: a usage and operating state of the sluice gate is monitored in real time through a sluice gate control cabinet, a sluice gate motor frequency converter and a sensor arranged on the sluice gate; monitored data is transmitted to adata acquisition instrument via the sensor; the controller is used for reading and recording data signals from the data acquisition instrument, the sluice gate control cabinet and the sluice gate motor frequency converter respectively, performing spectrum analysis on the data signals, extracting signal characteristic values of the data signals of all test points from spectrum analysis results, establishing an early warning mathematical model, achieving real-time monitoring and control of the sluice gate, and giving early warnings upon occurrence of exceptions of the sluice gate. The on-line state monitoring control method and the monitoring system are characterized by ability to reduce the maintenance cost and improve troubleshooting speed.

Description

technical field [0001] The invention relates to a control device for a gate of a hydropower station, in particular to an online state monitoring and control method and a monitoring system for a gate of a hydropower station. Background technique [0002] Due to the complex and changeable climate and the unpredictability of floods, once a flood occurs, the gate system must be in a high-speed, high-efficiency, and high-performance state to cope with the surge of floods. In order to ensure that the system can be put into use at any time, equipment maintenance is inevitable. For a long time, most domestic enterprises have adopted regular maintenance and troubleshooting. Regular maintenance is also called planned maintenance. No matter what the state of the equipment is, it must be repaired when it is due. However, the gate system will only be put into use during periods of high floods, and the demand for normal use is almost zero. This kind of maintenance method lacks economy an...

Problems solved by technology

However, the gate system will only be put into use during periods of high floods, and the demand for normal use is almost zero. This kind of maintenance method lacks economy and pertinence, often resulting in a great waste of manpower and material resources and increasing costs; while troubleshooting It means that the equipment is overhauled after a fault occurs, and the faults and defects of the equipment cannot be found early

Therefore, the existing technology has the problems of high maintenance cost and failure to eliminate faults in time
