作为一种调节系统电压的手段用。决定发电机进相深度的因素有发电机定子端部结构件温度限制压要求和厂用电电压降低幅度等。以阳逻电厂发电机进相试验为例析综合程序”作为分析工具运行的分析方法。摘要:作为一种调节系统电压的手段,发电机进相运行已在电网小方式电压偏高情况下按系统需要普遍采用。决定发电机进相深度的因素有发电机定子端部结构件温度限制、机组静稳极限、系统暂稳水平、系统调压要求和厂用电电压降低幅度等。以阳逻电厂发电机进相试验为例,采用生产运行部门常用的“电力系统分析综合程序”作为分析工具,围绕各制约因素,从生产运行角度阐述了一种具有实用性的发电机进相试验和运行的分析方法。

Generator's operation with leading power factor,as a means of voltage control,has been adopted widely as re quired in case of light load and high voltage.The limit of generator's operation with leading power factor depends on the limits of stator end temperature rise and static stability,transient stability,the affection on volt age and the fall of power sta tion voltage.At the base of an instance,i.e.the experiment of generator's operation with leading pow er factor in Yan gluo Thermal Power Plant ,this paper expatiates a practicable analytical method of generator's operation with leading power factor from the view of power system operation.This method uses PSASP,the most popular analy sis tool used by dis patching sectors,including those factors which would affect genera tor's opera tion with leading power factor.
