| 摘 要： | 励磁系统静态放大倍数K和有功功率对发电机电压下降特性有较大的影响.文中首先研究了不同K值下发电机无附加调差时的电压下降特性,然后分析了K值对附加调差效果的影响,最后基于单机无穷大系统计算分析了有功功率对发电机无附加调差时电压下降特性的影响.分析结果表明:当K较小时,机端电压随无功功率增加而下降较大,附加调差的影响被大大...

| Abstract: | The excitation static amplifying gain(K) and active power have great influences on the generator voltage droop characteristics.The effects of K on generator voltage droop characteristics without reactive current compensation are analyzed,and the effects of K on reactive current compensation are studied.At last,the influences of active power on the generator voltage droop characteristics are analyzed on a single machine infinite bus system.The results show that when K is smaller,the terminal voltage drops mo... |
