一种新型的FACTS设备--剩余电流补偿（RCC），完全克服了谐振接地的限制，完善了Petersen方法：中性点系统中的电压源逆变器（VSI）在继续供电的同时产生主动补偿剩余电流所需的电压。剩余电流补偿安装在一个110千伏电网，涉及18500公里的线路。RCC由使用GTO的5.5 MVA多级VSI组成。本文介绍了设计准则相对于有关的电网参数和闭环控制的基础上的中性点系统的导纳。现场试验证明了该方法的有效性。延长架空线路和电缆的完美接地故障管理可以创建规划谐振接地110 kV电网的审查指南，具有更高的可用性和电能质量。
A novel FACTS equipment, the residual current compensation (RCC), overcomes the restrictions of resonant grounding completely and make the method of Petersen perfect: a voltage source inverter (VSI) in the neutral system generates the voltage required to actively compensated the residual current whilst continuing the power supply. A residual current compensation was installed in an 110 kV grid, involving 18500 km of lines. The RCC consists of a 5.5 MVA-multi-level-VSI using GTOs. The paper describes the design criteria with respect to the relevant grid parameters and the closed loop control based upon the admittance of the neutral system. The effectiveness is proven by carried out field tests. The perfect earth fault management for both extended overhead lines and cables may create reviewed guidelines of planning resonant grounded 110 kV grids with higher availability and power quality.
