Description
technical field [0001] The invention relates to a state monitoring system and method for a computer monitoring system of a hydropower plant. Background technique [0002] The computer monitoring system of the hydropower plant is the core of the equipment control of the hydropower plant and the key equipment for the hydropower plant to realize the coordinated control of the source network. With the deepening of unattended and few-person-on-duty work and the higher and higher requirements of the power grid for the coordination ability of the hydropower plant's source network, the importance of the computer monitoring system of the hydropower plant is becoming more and more obvious. Once the computer monitoring system of the hydropower plant fails, it will seriously affect the safety of the hydropower plant equipment and even threaten the safety of the power grid. [0003] At present, there is no system integrating test and analysis specially developed for the computer monitor...
