Abstract


The main equipment of firepower plant is composed of three parts which are boiler, turbine and generator. The stable working of power station and electric net mainly depends on two sides,one is the balance between steam quantity of boiler and consume amount of turbine,another is pat balance between the amount of power generated and power used. Because of the instantaneous change of load,the relative parameters mentioned above are required to instantaneous change. In fact the two stable dynamic process are different in time. The adjustment and control system of boiler and turbine play an very important function.It is an effective in time control system to control the boiler and turbine,It is the main instrument to start,run and stop the generator and prevent the accidents. In order to insure the safety, stabilization and economic running of the firepower plant, the power plant has more and more higher requests.This paper aimed at the research of 125MW、300MW、350MW generators thermopower automation system of Jiuquan Iron & Steel Co. Based on deeper analysis of status in domestic and overseas,research every tache of thermopower automation system. Based on the development trend of thermopower automation of 125MW、300MW and 600MW power plant in domestic and overseas.Through the research of theory and function of thermopower automation and absorb the virtue of firepower plant widely, accomplish the originally design of automation control. According to deeply research the technics characteristic of coal-fired power unit in JISCO and control characteristic of firepower plant, accomplish the detailed design of automation system.According to the design project the hardware configuration is accomplished , the software and the control menu is empoldered. Takes place through the site of the accident, after investigation, analysis, found the cause of system instability.Find the cause of system instability, developed a technical solution.This thermal automation systems from design through configuration, debugging to use maintenance master plan, important work and considerations made comments at all stages it.
