Embodiment 1

[0049] An embodiment of the present invention, its steps are as figure 1 shown.

[0050] figure 1 Step 1 described in is to obtain basic information: obtain basic information from the power grid dispatching operation control technical support system and dispatching operation management system, including power grid operating condition information, equipment failure outage information, external environment information of the power grid, and resource requirements for faulty equipment maintenance Information, resource information currently available for maintenance, candidate recovery plan information and recovery delay loss information, and probability information of failure after equipment maintenance.

[0051] The equipment failure and outage information refers to equipment that cannot be connected to the grid due to defects, and can only be put into operation after repairing and eliminating defects. The maintenance resource requirements for faulty equipment include the mater...

Abstract

The invention discloses a power transmission and transformation equipment maintenance plan decision method under the power grid emergency state, belonging to the technical field of power system automation. The method includes calculating the maintenance task completion delay loss time correlation factor based on the recovery scheme and target; calculating the maintenance task cost performance through the combination with the maintenance task resource demand information; calculating the sorting factor of the maintenance task by applying the comprehensive probability of fault regeneration of maintenance task related equipment; and determining the maintenance task plan by taking the maintenance task sorting factor as the main body and by taking the principle that the maintenance task resource demand is closest to the residual available resource as an auxiliary. The method provided can improve the utilization efficiency of the maintenance resources under the power grid emergency state, promote the smooth implementation of the recovery pre-arranging plan, provide technical support, improve the handling capability under the power grid emergency state, and reduce the power loss.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular the invention relates to a decision-making method for power transmission and transformation equipment maintenance plan under an emergency state of a power grid. Background technique [0002] Making a reasonable power transmission and transformation equipment maintenance plan has always been a problem that the power grid operation management department attaches great importance to. A lot of research has been done on the power transmission and transformation equipment maintenance plan under the normal operation of the power grid, and some more practical planning and decision-making methods have been formed. It not only effectively improves the comprehensive benefits of equipment operation and maintenance, but also provides an important guarantee for the safe and stable operation of the power grid. [0003] Affected by factors such as the external natural e...
