【正文】 ance grounding and lowresistance grounding according to the current of the grounding resistance. In the distribution works in China, the grounding mode of neutralpoint grounding through arcsuppression coil is widespreadly used, which greatly enhanced the supplying reliability of the power grids. However, with the increasing of grid size, the system operation modes have changed a lot, and the traditional manual adjustment of the arcsuppression coil is very difficult to achieve realtime detection of the grounding capacitive current and automatic pensation, and this makes the effect of grounding current pensation very poor, which is unable to meet the requirements of distributionautomation. Therefore, the automatica tracking pensation arcsuppression coil and its control technology came into being. The work of this article is carried out, targeted at the power system characteristics, to propose new and effective arcsuppression coil control method . This paper first introduces the current development of arcsuppression coil control technology, including several existing types of arcsuppression coil, as well as several existing automatic control methods of arcsuppression coil: neutral point displacement voltage method, dynamic tuning control method , signal injection method and so on. And then use the MATLAB simulation to analyze the various control methods , and study those control theoriesdeeply. Then according to the above theoretical analysis and study, and based on the original methods, birng up a new control method for arcsuppression coil Capacitive current incremental method. And then through the MATLAB simulation analysis to verify its feasibility and errors. In which, in order to search for the ideal range of additional capacitance through the error analysis , this article has done a lot of simulation analysis. At final, I sum up my design.
