电力系统中性点接地方式浅析

摘要

The neutral grounding method of power system refers to the manner in which the neutral point of a generator or a transformer is connected to the ground. Each neutral grounding method accommodates both advantages and disadvantages, involving a variety of factors, such as power grid operation safety, power supply reliability, the co-ordination of voltage and insulation, circuit breaker selection, protection methods, grounding design.%电力系统中性点接地方式是指电力系统中发电机和变压器中性点与地的连接方式，中性点不同接地方式各具优点与不足，涉及电网安全运行、供电可靠性、过电压与绝缘的配合、断路器选用、继电保护方式、接地设计等多种因素。
