DECISION METHOD OF CONDITION-BASED MAINTENANCE TO POWER GRID RISK

摘要

Disclosed is a decision method of condition-based maintenance to a power grid risk. The method includes: calculating a contribution of each device to be maintained of a plurality of devices to be maintained to the power grid risk in a current operation mode of a power grid, and determining the contribution of the each device to be maintained to the power grid risk as a set value corresponding to the each device to be maintained; determining a maintenance decision order of the devices to be maintained according to a descending order of set values corresponding to the devices to be maintained; and sequentially making maintenance decisions on the devices to be maintained according to the determined maintenance decision order. In the disclosure, a contribution of each device to be maintained to a power grid risk in a current operation mode of a power grid is determined; a decision order of the devices to be maintained is determined by arranging the contribution in descending order; and a maintenance period is sequentially determined based on a minimum cumulative risk according to the decision order of the device to be maintained. Thus the maintenance safety is improved.
