摘要
近些年随着我国配电网的全面改造,配电网的结构发生了变化,而配电网中性点不同接地方式的选择关系到电网的安全可靠运行。讨论了配电网主要采用的几种接地方式及各自的优缺点,对采用不同的接地方式从内外过电压防护﹑供电可靠性等方面进行了分析,探讨了配电网中性点接地方式选择的一般原则及发展趋势。
In recent years, distribution network of China is facing to reconstruction. The structure of distribution network has been changed, the choice of neutral grounding modes is vital important to distribution network safe operation. This paper discusses several grounding modes and their merits and deficiencies adopted by distribution network. The problems about over-voltage level, reliability of power supply are analyzed. The principle and development trend of neutral grounding modes for distribution network are discussed.
