Gate lifting and water controlling system for hydropower station

Abstract

The invention provides a gate lifting and water controlling system for a hydropower station, wherein the hydropower station is provided with a first power source, a second power source and a third power source, the first power source and the second power source are standby power sources, the third power source is a frequently-used power source. The system comprises a liquid level monitoring module, a gate monitoring module, a control module and a power source regulation and control module, wherein the liquid level monitoring module comprises a liquid level meter, the control module is connected with the liquid level monitoring module and can control a gate to ascend and descend, the gate monitoring module can collect the data of the gate and transmit the data to the control module, and the power source regulation and control module is also connected with the first power source, the second power source and the third power source, can switch among the three power sources, is also connected with the gate and supplies power to the gate. According to the invention, safe and economical operation of the hydropower station can be guaranteed, the gate opening degree can be accurately controlled according to the forebay water level, and the labor intensity and workload of personnel are relieved; and the electric interruption time can be shortened from minute level to second level, so that the equipment operation is safer and more reliable.

Description

technical field [0001] The invention relates to the field of electricity control and adjustment, in particular to a water control system for lifting gates of a hydropower station. Background technique [0002] The control of the flood gate of the hydropower station is very important, especially at the critical moment of water storage and flood discharge. If the power supply system of the hydropower station collapses due to a fault and the factory power disappears, and the backup power supply cannot be switched in time, it will easily lead to very serious consequences. However, the existing backup power supply of some hydropower stations cannot be switched automatically, and it is completed by the on-duty personnel, such as manually starting the diesel generator. However, there are fewer on-duty personnel, and there may be older problems, which will make the power switch in an emergency untimely and take a long time to operate. Therefore, how to achieve timely switching bet...

Problems solved by technology

[0003] At the same time, in some hydropower stations, especially small hydropower stations, the relationship between the lifting height of the floodgate and the water level and flow of the forebay is mostly judged by the on-site experience of the personnel, and it is impossible to make an accurate judgment; In this situation, misoperation and misjudgment are prone to occur.
