摘要
通过计算和现场实测,得到了750 kV宝鸡变电站和处于宝鸡换流站周围100 km内的330 kV、110 kV变电站内的变压器中性点直流电流,并分析了对变压器的运行影响,提出了今后还需开展的重点工作,为今后西北电网的直流输电对交流变电站变压器的影响提供了数据。
The neutral point DC currents of transformers of the 750 kV Baoji Substation and all the 330 kV and 110 kV substations within 100 km away from the Baoji Converter Station are calculated and measured in the field,and influences of the currents on the operation of the transformer was analyzed.This paper proposed the jobs to be done in the future,and provided some data for the oncoming DC power transmission project in the northwest grid on the transformers in AC substations.
