| Abstract |
A novel FACTS equipment, the Residual Current Compensation (RCC), overcomes the restrctions of resonant grounding completely and makes the method of Peterson perfect: a Voltage Source Inverter (VSI) in the neutral system generates the voltage required to activily compensate the residual current whilst continuying 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 3-level-VSI using Gate Turn Off Thyristors (GTO). 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. |
