With the continuous expansion of power distribution network, the power grid extends to the remote areas, and the voltage quality problems of high voltage distribution network have gradually emerged. The application of series compensation capacitor can effectively improve the voltage of loads at the end of the distribution network, and can achieve the goal of improving voltage quality. Meanwhile, the research of protections for the series compensation capacitor body has become a research focus, which requires the protection control device can find fault in time and cut off capacitor quickly. The research focuses on the protection and control of series compensation capacitor based on fast switch, which is to solve the problem of fast protection and control of series compensation capacitor in the distribution network. According to the characteristics of each component, a protection scheme for fast switching series compensation capacitor in distribution network is developed, including the MOV and capacitor protection.
