Grid fault equipment analyzing and reasoning method based on rule tree

The invention relates to a grid fault equipment analyzing and reasoning method based on a rule tree. The method comprises the following steps: (1) establishing the rule tree; (2) acquiring the real-time fault information of a power grid; (3) presuming one piece of equipment as fault equipment, and acquiring a rule tree thereof; (4) taking out the root node of the rule tree, pushing into a reasoning queue, and performing reasoning on the root node according to steps (5) and (6) by adopting a recursive algorithm; (5) taking one node out of the reasoning queue for serving as a parent node, and acquiring a child node set of the parent node; (6) circularly reasoning the child node set, wherein the termination condition is that one child node is a termination node or the reasoning queue is empty, wherein if the presumed fault equipment is circularly reasoned to the termination node, the presumed fault equipment is real-time fault equipment; (7) returning to the step (3). By adopting the method, the intelligence and universality of grid fault analysis and reasoning can be enhanced, automatic analysis of the fault equipment is assisted, the accident handling time is shortened, and the accident handling efficiency is increased.
