Zusammenfassung:The invention belongs to the technical field of power system safety risk assessment, and particularly relates to a power distribution network operation risk assessment method and device based on a three-dimensional derived risk field, and the method comprises the steps: building the three-dimensional derived risk field according to the spatial information of a power distribution network operation site, acquiring real-time position information of a preset risk subject in the three-dimensional derived risk field; traversing a preset risk source list based on the real-time position information, and calculating derived risk values of the risk sources one by one; superposing the derived risk values of the risk sources to obtain a total derived risk value by using the risk field assessment model of the multiple risk sources; and when the total derived risk value is greater than a risk threshold value, giving risk early warning. On the basis of power distribution network engineering field operation risk identificati
