发电机中性点接地方式及运行分析

Discussion on the types of generater neutral grounding and the analysis for their operation

本文阐述了发电机中性点各种接地方式,并对其运行作了分析比较.在由大容量发电机构成的现代电网中,经副边带高电阻的配电变压器接地优于其它接地方式。

Various types of generater neutral grounding are discussed. they are analized and compared in their operation behaviour. In modern powersystem made up of large capacity generaters, the type of grounding through distribution transformer with secondary high resistor prevails over one' s else. This type of grounding will be adopted extensively in our country.
