Description

Technical Field

[0001] The present invention relates to the technical field of optimized dispatching and monitoring of hydropower stations, and particularly relates to a method for automatically converting the status color display of primary equipment in a hydropower station monitoring system. Background Art

[0002] At present, most hydropower stations in China use a monitoring system to remotely operate and monitor the equipment in the power station. Operators need to keep track of the operating status of the main primary equipment in the power station in real time for safer dispatching. For the convenience of operators' operation and monitoring, the main wiring diagram is mainly used at present, and the operating conditions of all the main primary equipment in the power station are shown through a single diagram. However, only several colors are set for the generator sets and switches to show some statuses, and some status colors need to be manually set and displayed by the operators. The remaining primary equipment has only one graphic color, resulting in the operators being unable to clearly understand the status of all the main primary equipment and increasing the monitoring pressure on the operators.

[0003] Therefore, in order to intuitively display the status of each primary equipment and reduce the monitoring pressure on the operators' monitoring screens, a method for automatically converting the status color display of primary equipment in a monitoring system is an urgent problem to be solved. Summary of the Invention
