As the scale of the power grid expands, the demand for equipment maintenance also increases, and the efficiency and correctness of maintenance planning for grid operators are required to be improved along with it. In order to improve the efficiency of power grid equipment maintenance analysis, this paper designs a power grid security and stability calculation tool based on maintenance sensitivity and network reconfiguration. Firstly, the method of obtaining the power grid model data by the system is introduced, and the power grid risk under the condition of simultaneous maintenance of multiple equipment is analyzed. The equipment maintenance sensitivity is sorted to find out the key maintenance equipment with the highest risk. Then, the method of network reconfiguration is used to solve the problem of power flow over-limit and loss increase caused by equipment maintenance. Finally, the feasibility of this method is verified on the actual model of a provincial power grid. The conclusion proves that it has a certain guiding role in the preparation of power grid maintenance plan.
