The Research Of Nucler Power Plant Electrical Monitoring Network

Currently, our country develops installed of the nuclear power and advances domestic participation process of the nuclear power hardly, domestic nuclear power project has just been unfolding, with technology continues to evolve and the accumulation of practical experience, high level of the nuclear power technology in China began to start, which has begun to independently design, install and test distributed control system of the nuclear power, greatly improved the automation level of the nuclear power plant.However, the nuclear power plant electrical monitoring network will focus on monitoring the nuclear power plant electrical system, their technical and management level has lagged behind the development of DCS, which is the "shortcoming" for development of the nuclear power plant automation, as the high requires of the nuclear power unit on the electrical system safety,economic operation, dispersed monitor and control of conventional methods no longer meet the current form of the development. In the context of developing nuclear power technology and advancing domestic participation, researching network of electrical monitoring system, can enhance electrical equipment technology and management level of the nuclear power plant, coordinate simultaneous development in instrumentation and electrical automation of the nuclear power plant, comprehensively improve the level of automation and management level of the nuclear power plant, enhance the advantage of the lower costs and competitiveness of the nuclear power plant, so this topic has very important practical significance.According to the example of the fossil-fuel power plant on electrical monitoring system, this article carried on technical analysis and economic analysis, and according to the structural features of the nuclear power plant electrical system, reference to the engineering practice of the fossil-fuel power plant and technology method of the electrical monitoring system, using the advanced technology of the field bus, this article carry out research and feasibility studies on networking scenario of the nuclear power plant on electrical monitoring system, and carried on compare to varieties of networking options, in particular, it carried on real-time and reliability analysis on field bus networking scenario, obtained the advantages and disadvantages of various network scenario. On the basis of carrying out a full research and analysis, by using the field bus technology, this article proposed network scenario of the nuclear power plant electrical monitoring system. Comparing the program and other programs, this has the obvious advantages of advanced technologies, saving investment, easy maintenance and so on. With the development of the nuclear power technology, by using field bus technology which composes the scenario of the electrical monitoring system, we believe it will be widely used.
