摘　　要：介绍了我国电力系统配网谐振接地的现状及发展趋势,给出一种基于双CPU结构和晶闸管的调容式消弧线圈的工作原理。二次侧电容器组的分配原则,电容电流测量方法以及消弧线圈自动控制系统的构成, 介绍了本研究所构建的6 kV试验动模系统。试验结果表明:设计的方案和一次二次设备参数正确。This paper analyzed the present situation and the direction of future development of the resonant grounded power system. The operation principle of arc suppression coil based on thyristor series capacitors and double CPUs was presented. The distribution principle of the secondary switching capacitors, the method for measuring the capacitive current and the composition of arc-suppression coil automatic control system were detailed. This paper also introduced the 6kV dynamic simulation system constructed by this research. The simulation result shows that the parameters of primary and secondary equipments are correct and the system operates rapidly and correctly.
