| 摘 要： | 电力系统中性点接地方式主要是技术问题,但也是经济问题.文章遵循电压、电流互换特性这一基本理念,主要从问题的性质、研究的目的、发展简史、内部过电压、谐振接地方式的优化、电缆网络、运行特性与经济效益等方面,对中压电网两个有代表的中性点谐振接地方式与低电阻接地方式,进行了分析和论证.同时指出,在选定方案的决策过程中,应当利用系统工程的观点,结合电网的现状与发展规划,认真进行技术经济比较后确定.国内外的理论研究和实践经验表明,谐振接地方式符合发展方向.

| Abstract: | Power system neutral grounding is of technical issue but also an economic issue.This paper analyzes and discusses two typical neutral grounding schemes,i.e.the resonance grounding and low resistance grounding,and points out when selection of grounding scheme,decision shall be made based on system engineering point of view,incorporated with present state and develop- ment program and after technical and economical comparison.Theoretical study and practical experience both at home and abroad has shown that resonance grounding is most suitable to development trends. |
