The course of network reconstruction in all levels of substation,it is possible for closed-loop operation. In case the crew cannot get a grip of closed-loop situation in time,the hid-den dangers may appear and the safe operation of power grid will be interfered. In view of this, the closed-loop monitoring system was developed for coal mine distribution network,based on auto-tuning arc-suppression coil. Moreover,the fundamental of morning system was introduced, and its design was also researched. The actual operation showed that the monitoring system is mature and reliable,being able to timely and accurately j udge the network in the state of close-loop or not.
