Abstract

The invention provides a microgrid fault prediction method and device and electronic equipment. The method comprises the steps: obtaining a fault tree model of a microgrid; calculating a minimum cut set and a minimum path set of the fault tree model; calculating the importance degree of the occurrence of a top event according to the calculated minimum cut set and minimum path set when each basic event happens; performing the ordering of all basic events based on the importance degree of the occurrence of the top event when each basic event happens to obtain an ordering result; sequentially detecting all basic devices in the microgrid according to an ordering result, thereby achieving the prioritized detection of the basic devices with the higher importance degrees, achieving the quick locating of fault equipment, and saving time and labor.

Description

technical field [0001] The present invention relates to the field of microgrids, and more specifically, to a fault prediction method, device and electronic equipment for microgrids. Background technique [0002] Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. With the continuous development of national micro-grid demonstration projects, more and more micro-grids have been implemented in enterprises or gardens. [0003] When the micro-grid fails, it is necessary to determine the faulty equipment that causes the micro-grid to fail. At this time, it is necessary for technicians to detect each device in the micro-grid one by one, which is blind to a certain extent, takes a long time, and wastes manpower. Contents of the invention [0004] In view of this, the present invention provides a micro-grid failure prediction met...
