Development And Application Research Of Three Gorges Generating Units Monitoring And Trendency Analysis System

As important national production sector, how to ensure the safe and stable operation of a hydropower station is a focus of the study in electricity production sector. Generating units running state will have a direct bearing on the production of the entire power station. In order to enhance its operational safety and reliability, we can do real-time monitoring and quantitative analysis for the various state information of operation units and provide useful information for the operation management and forecasting maintenance.Three gorges hydropower plant trendency analyse system is a surveillance and track analyse system, that set on power-generating units. This system imports computer and network system into equipment surveillant and trend analytical field, getting local real-time datum of every distributed unit by Intranet network, realize online surveillant function and can reflect the status of every unit. Integrated with abundant experience of expert, this system can greatly help hydropower plant to healthy run and give constructive advise of unit maintenance. Users can visit this system by Internet/Intranet at any other place of the world to learn or analyse the status of unit, read the diagnostication report of unit, so that it's possible for them to find the hidden malfunction of unit earlier, avoiding the severe accident occurring. Meanwhile the datum of every unit is saved in the status information database for users to look back and analyze the occurrence accident. And this system also can provide the needed status information for unit maintenance, so it's a necessary system for safety and economic run in hydropower plants.The following questions are mainly discussed in the thesis:①The developing process of the technology of situation monitoring and tendency analyzing for waterwheel electric generating set, and the current situation and developing tendency of the tendency analyzing system;②The role, function and significance of the system of situation monitoring and tendency analyzing for waterwheel electric generating set;③The data analyzing method for the system of situation monitoring and tendency analyzing for waterwheel electric generating set;④The introduction of the design and realization process of the system of situation monitoring and tendency analyzing for waterwheel electric generating set; ⑤The introduction of application methods of the system and practical guidelines for the electric power plant.Since the system had been put into operation,it has played a tremendous role in daily production, equipment diagnosis, analysis of various aspects of the accident and became important assistant of operation and maintenance personnel. It provided a powerful technical support for the production safety of the Three Gorges power plant and became one of the core software for accident analysis and prevention in Three Gorges Power Plant。...
