600MW机组制粉系统电源配置的改造

Energy Configuration Reconstruction of Milling System in 600MW Unit

分析了神华河北国华沧东发电有限责任公司600 MW机组直吹式制粉系统电源配置存在的缺陷,通过对磨煤机电机电源重新分配和给煤机低压母线分段解决了电源配置问题,从而提高了制粉系统电源的可靠性,消除了发生停炉、停机事故的隐患,具有一定的推广价值。

This paper analyzes the objection of power supply configuration of 600 MW directly blowing milling system in Hebei Guohua Cangdong Power Limited Liability Corporation,through the redistribution of the source of coal mills and separation of the coal feeder low voltage bus subsection the power reliability of milling system is raised, so as to eliminate accident hidden trouble regarding to the out of running of the boiler or the turbine. So it＇s of tbe popularized value for other power plants.
