摘要
在现代电力系统中,能量中心日益远离负荷中心,尤其是水利发电,因此远距离大容量输电势在必行。为了提高经济效益,广泛采用串联或并联补偿技术,提高输电线路的容量和稳定性。在这种运行条件下,电力系统由于参数配合不当,发生自励磁现象的可能性大大增加。通过介绍电力系统自励磁的定义,产生的条件,以及几种典型的分析方法,对自励磁现象加以概述。
The power station in the large power system（especially the hydraulic power station） is usually located far from the load center.Therefore the extra high voltage long range power transmission is inevitable.The generator will likely to be self excited due to the long transmission line charging current under no load state.This paper introduce the definition of self excited,generated conditions,and typical methods of its analysis,besides this summarized on the phenomena of sele-excitation.
