[Abstract]:With the rapid development of science and technology, the traditional secondary automation system of hydropower gradually reveals the problems such as the difficulty of information sharing, the low degree of integration, the big difference of technical standards, the insufficient coordination ability of source network, the limited ability of intelligent decision-making, and so on. It is difficult to play a strong supporting role in the power generation link and can not realize the concept of smart grid. This paper analyzes and studies the operation status and shortcomings of the existing automatic systems in hydropower plants, and puts forward the application of advanced computers. Automatic control and information communication technology, and draw lessons from the research results of smart grid, through the integration of all kinds of operation and production data of hydropower plants, from the basic software and hardware platform, hydropower standard communication bus, The CIM model of hydropower plant (public information model of hydropower plant, describing all the main objects of hydropower plant) is designed, and an integrated management and control system to meet the needs of practical application is constructed, and the unified management of hydropower plant is realized. Scientific dispatching and safe operation. The main contents and results are as follows: 1) the background of hydropower plant automation system and the present situation at home and abroad are analyzed. According to the actual situation of hydropower plant, the main problems existing in the existing professional automation system are analyzed. This paper demonstrates the necessity and feasibility of the construction of integrated management and control system. (2) A unified model standard, Hydropower CIM Model Specification, which is based on IEC 61850 / IEC 61970 standard for the production and operation equipment and resources of the whole plant, is put forward. And the concept of hydropower standard communication bus based on IEC 61850 / IEC 61970 standard. On this basis, a new standard communication bus is constructed, which is based on integrated control and control platform, high speed optical fiber transmission network as physical foundation, and hydropower standard communication bus as standard. Based on the CIM model of hydropower plant, the integrated management and control distributed architecture of hydropower plant is developed, which can realize the integration of the automation and information system of hydropower plant, support the economic operation, and support the decision of condition based maintenance. Based on the analysis of typical engineering application, this paper proves that the integrated control and control of hydropower plants can automatically complete all kinds of production information collection, measurement and control. The benefits of protection, metering, testing and economic operation of hydropower plants, dam safety analysis and evaluation decision support, flood control decision support, condition maintenance decision support, safety protection multi-system linkage application and so on show that the system is leading. Innovation and engineering practicability.
