A distribution network maintenance method including a microgrid

Abstract

The invention provides a method for maintaining a distribution network including a microgrid, aiming at solving the technical problems in the prior art that the maintenance of the distribution network is difficult and it is easy to misoperate during the maintenance process. The present invention provides a distribution network maintenance method containing a microgrid. The maintenance personnel perform simulation operations on the power grid branch to be maintained in advance, and identify the power grid branch to be maintained and the power distribution equipment related to the power grid branch. Then, the marked grid branches and power distribution equipment are monitored, and the maintenance personnel can maintain the distribution network according to the simulated operation when the status of the grid branches and power distribution equipment does not change before the actual operation. This scheme can effectively prevent maintenance personnel from misoperating the distribution network, and this method does not need to frequently review the maintenance scheme of maintenance personnel during actual operation, which reduces the labor intensity of relevant personnel. It is beneficial to improve the maintenance efficiency of the distribution network.

Description

technical field [0001] The invention relates to a method for maintaining a distribution network, in particular to a method for maintaining a distribution network containing a microgrid. Background technique [0002] The distribution network is an infrastructure for the transmission of electrical energy. During the operation of the distribution network, the distribution network generally requires safe and reliable operation, that is, the distribution network does not allow large-scale faults in the distribution network to cause large-scale power outages during the operation process. Therefore, the distribution network needs to be regularly maintained during the long-term operation to prevent large-scale faults in the distribution network. [0003] In the prior art, with the application of new energy sources, the working mode of the distribution network generally works in the working mode of multiple power sources. For example, solar power stations and small hydropower stati...
