Fault location method and device and storage medium

The invention relates to the technical field of equipment intelligent operation and maintenance, and discloses a fault location method and device and a storage medium, so as to improve the real-time property and accuracy of fault location. The method of the invention includes the steps of setting at least two measurement points associated with different dimensions in a device to be fault located,and determining a one-to-one corresponding fault matrix for each fault type; acquiring time-series based abnormal state information data of each measurement point to construct an abnormal state information eigenvalue matrix; calculating a matching degree of the abnormal state information eigenvalue matrix to be analyzed with each fault matrix, and locating the fault type corresponding to the faultmatrix with the highest matching degree as a current fault type; according to a preset sampling period, determining whether the accumulated time when the currently located fault type occurs continuously in the corresponding s
