外文资料Integrated Auto mation of Power Plant Electrical SystemAbstract: Electrical system for power plant automation level of the relatively backward state, the paper analyzes the electrical system in power plant automation technology in an integrated feasibility, necessity, and several key issues, proposed the use of field bus technology, new ideas, and gives Specific implementation plans. Keywords: Plant electrical system Fieldbus control wire system Integrated Automation1 IntroductionIntegrated automation technology has been applied in power system substations, and decentralized and distributed technology [1] is widely used in integrated automationsystem.Comparedtothecentralized technology ， this technology has many advantages such as simple and flexible structure, high reliability ,convenient installation and low cost of maintenance. However, integrated automation technology has not been widely used in power plant electrical system. Protective relay and security devices of electrical system run in a self 9-governed state ， which haven’t formed an integrated electrical automation system. Therefore The managing and maintaining level hang behind. Latterly more and more power plants, especially those newly constructed are interested in the automation of power plant electrical system and its relationship with traditional distributed control system (DCS) .This paper analyzes the actuality of power plant electrical system, brings out a new ideal of application ofmicrocomputer9-basedintegratedautomation technology to power plant electrical system, and gives concrete realization of the program.2 The status of power plant electrical system The electrical system discussed in this paper is mainly referred to the protection , measurement...
