Micro-grid short circuit fault diagnose method based on intelligent electric meter

The invention relates to a micro-grid short circuit fault diagnose method based on an intelligent electric meter. The method comprises the main steps: installing a micro-grid diagnosing host according to a fixed parameter; obtaining real-time data of a micro-grid; calculating a micro-grid feeder line branch; and comparing a calculation result and a reading number of the intelligent electric meter. According to the micro-grid short circuit fault diagnose method based on the intelligent electric meter, a computer of an existing micro-grid controlling system serves as the micro-grid diagnosing host, hardware devices are not needed to be additionally arranged, under the situation that the complexity degree of the system is not increased, short circuit faults in a micro-grid can be timely found and located through utilization of an existing intelligent electric meter in the micro-grid system, and operating personnel are reminded of carrying out processing. In addition, basic parameters of a diagnose system can be modified by the micro-grid operating personnel, and accuracy of a diagnose result is improved.
