A situation-aware fault self-healing system for distribution network with distributed generators

Abstract

The invention discloses a distribution network fault self-healing system based on situation awareness, which comprises: a PMU information acquisition module connected with a wireless communication module; a PMU information acquisition module connected with a wireless communication module; a PMU information acquisition module connected with a wireless communication module. The wireless communication module is connected with the PMU information acquisition module and the MYSQL database module. A MYSQL database module is connected with a multi-source data processing module, a distributed power output prediction module and an observability analysis module; Multi-source data processing module: multi-source data processing of distribution network, observability analysis module: observability analysis of distribution network. The output prediction module of the distributed generation is connected with the fault self-healing module; Fault self-healing module: to provide data basis for active distribution network power flow calculation, control and operation, to complete network reconfiguration. The invention solves the technical problems that the prior art has the advantages of solving theproblem of traditional distribution network fault recovery and reconfiguration, and can not effectively carry out fault self-healing to realize distribution network network reconfiguration and the like.

Description

technical field [0001] The invention belongs to the field of distribution network fault self-healing, in particular to a distribution network fault self-healing system including distributed power sources based on situation awareness. Background technique [0002] Actively controlling the operation status of the active distribution network is the core concept of the active distribution network, which requires that in the process of real-time operation control of the distribution network, the dispatching and control centers of the distribution network at all levels must master the real-time operation of the entire network. State information, which also puts forward real-time and rapid requirements for state estimation methods suitable for active distribution networks. Therefore, for the stable operation and reliable control of the distribution network, realizing the self-healing control after the distribution network fault has important theoretical value and engineering signif...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a distribution network fault self-healing system with distributed power sources based on situational awareness to solve the problem of traditional distribution network fault recovery and reconstruction in the prior art, but does not consider distribution The impact of traditional power supply on distribution network fault recovery and reconstruction makes it impossible to effectively perform fault self-healing to realize distribution network network reconstruction and other technical problems when the distribution network fails.
