摘要：
The grounding of a Back-to-Back system is necessary in order to determine the valve insulation level. The commonly used method is direct grounding of the negative side of the DC voltage but this method requires the full of the DC voltage. The authors proposed a neutral point grounding method with a reactor. The authors studied the required value of the reactor. Then the authors studied the miniaturization method of the reactor. © 2020 The Institute of Electrical Engineers of Japan.
