Abstract

The invention provides a main distribution power failure plan selection method and device, and relates to the technical field of power distribution management, and the method comprises the steps: determining a maintenance risk impact factor and a maintenance time impact factor; calculating a power failure risk evaluation value according to the maintenance risk influence factor; calculating an association rule of the maintenance time influence factor and the maintenance time, and calculating a power failure time estimation value according to the association rule; calculating an objective function of coordinated operation of the main distribution network according to the power failure risk evaluation value and the power failure time estimation value; calculating the minimum value of the target function; and selecting the power failure plan with the minimum value obtained by the target function from the plurality of power failure plans. The optimal power failure plan can be selected by considering the power failure time and the maintenance risk.

Description

technical field

[0001] The invention relates to the technical field of power distribution management, in particular to a method and device for selecting a power outage plan of a main distribution network. Background technique

[0002] Power outage maintenance of transmission lines can effectively improve the reliability of power supply, but power outage maintenance needs to formulate a scientific and reasonable power outage plan. At present, the blackout plan is manually formulated, and the planner usually formulates multiple blackout plans, compares and selects the best blackout plan for implementation. However, when making a choice, the planners usually proceed from the actual needs of their own business. When coordinating the outage plan of the main distribution network, it is necessary to take into account the mutual exclusion and coordination between equipment outage time optimization and maintenance risk. How to take into account the outage time and maintenance risk ...
