This paper has great social benefit and economical benefit.Electric power system plays an important role in our national economy. Whatever it is a fossil power plant or hydro power plant; their control systems are complicated. The adjustment and management of electric power system need more powerful comprehensive management and optimized control function. Fossil power unit has developed into large capacity and high parameter from middle temperature, middle pressure, middle and small capacity. As called unit, it means to consider boiler, turbine and generator as a one unit, design automation control system and configuration of central control room from this point of view. Distributed Control System(DCS)makes system function distributed, rank by using micro computer. It keeps closed relation and coordinated action between every sub system and control center by using advanced communication technology. It has many advantages for example high reliability, high flexible, and powerful system function. Now DCS has widely applied in electric power control system.Today, DCS takes CIMS as a target; combine the process control automation and the information management automation by using new control method, intelligent instruments, expert system and network technology etc, to realize the comprehensive integrated system of management and control. This article discussed control principle and control requirement of process control system in fossil power plant. These control not only request safety and reliable, but also request economic operation. And systems between have very closed relationship. We use DCS to fulfill automation control in power plant, not only ensure the safety and reliability of control system, but also ensure the real time response speed. And DCS has flex configuration, large capacity, reasonable architecture and consummate protection step to satisfy all the demands from the process. This article details takes an engineering project to introduce the DCS automation control in whole power plant process.This article also analysis the problems of designation and application in automation control system in our country. And proposed some opinions and suggestions to the new topic of automation development in fossil power plant.This article also studies the current situation and development outlook of intelligent control system, field bus technology and integrated system model in fossil power plant to search for countermeasure of Chinese fossil power plant.
