Problems solved by technology

[0003] The remote centralized control signals of traditional cascade hydropower station groups are classified by the local control unit (LCU) of the hydropower station, and a single local control unit contains multiple devices. In this case, it is impossible to automatically or manually control the signal of the maintenance equipment by controlling the local control unit, resulting in false alarms and flashing of the equipment maintenance signal, which affects the real-time normal monitoring of the equipment. For example, the local control unit (LCU) of the switch station of the centralized control hydropower station During the maintenance of a certain line, the test signals of equipment joint debugging, monitoring point matching, blocking test, detection, calibration, etc. are misreported, flashed, and a large amount of invalid information is sent in a short time, which seriously interferes with the judgment and processing of the on-duty staff, and seriously affects the on-duty Real-time monitoring of safety, quality and efficiency of staff equipment

Description

technical field [0001] The invention relates to the technical field of cluster control of cascade hydropower stations, in particular to a system and method for automatically controlling control signals of cascade hydropower station groups. Background technique [0002] Most of the hydropower stations are located in remote mountainous areas, far away from the city. In order to improve the working environment of hydropower station employees and increase the utilization rate of water energy, hydropower companies generally build remote centralized control centers to realize remote real-time monitoring, start-up and shutdown, load adjustment, and switching of cascade hydropower station groups. Operation and other controls. However, with the increase in the number and installed capacity of remote centralized control hydropower stations in the cascade hydropower station group, more and more equipment signals are sent to the centralized control center from the hydropower stations un...
