Abstract

The invention discloses a monitoring method and apparatus for a distribution network. The method comprises: a multi-layer topological model of a distribution network is established, wherein the model is used for representing a topological structure among all devices in a distribution network; state information of the distribution network is collected from a data source; devices are analyzed according to the multi-layer topological model and the state information so as to determine whether a fault device exists in the distribution network; if so, a fault result is outputted, wherein the fault result contains a power grid fault and/or communication fault. According to the invention, a technical problem that a fault existing in the power distribution network can not be fount timely in the prior art can be solved.

Description

Technical field [0001] The present invention relates to the field of power grids, and in particular, to a monitoring method and device for distribution networks. Background technique [0002] In the power system, with the construction of the distribution automation system, the operation range of the distribution network is gradually expanding, and the failure of the distribution network will directly cause the user's power consumption to be seriously affected. Therefore, timely detection and handling of faults in the distribution network can shorten the time for users to be affected by the above-mentioned faults, and improve the efficiency of fault maintenance of the distribution network. However, at present, there is no plan for fault monitoring of the distribution network. The user can only obtain fault information in a "passive" way of repairing, and then start the fault handling process to solve the problem. [0003] In addition, in related technologies, it is also impossible ...
