摘要
结合上海市电力公司奉贤供电公司电网的实际情况,对奉贤地区35 kV及10 kV电网的中性点接地方式进行研究分析。本文以异频注入法对奉贤电网28个变电站的电容电流值进行测量,并以奉贤电网28个变电站的实测电容电流值为依据,确定这28个变电站的中性点接地方式。
Combined with actual situation of Fengxian Power Supply Company,the neutral grounding modes of Fengxian 35 kV and 10 kV power grid are studied in this paper. The different frequency injected method is used to measure the capacitive current of Fengxian 28 substations,and the neutral grounding modes of the 28 substations are determined based on the measured values of capacitive current.
