Abstract

The invention discloses a distributed power distribution network fault self-healing system based on situation awareness, which includes: a PMU information collection module connected with a wireless communication module; the wireless communication module is connected with the PMU information collection module and a MYSQL database module ;MYSQL database module is connected with multi-source data processing module, distributed power output prediction module and observability analysis module; multi-source data processing module: process multi-source data of distribution network, observability analysis module: Analyze the observability of the distributed power generation; the distributed power output prediction module is connected with the fault self-healing module; the fault self-healing module: provides the data basis for the power flow calculation, control and operation of the active distribution network, and completes the network reconstruction; solves the existing technology There are technical problems such as solving the problem of traditional distribution network fault recovery and reconstruction, and failure to effectively perform fault self-healing to realize distribution network network reconstruction.

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...

AI Technical Summary

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.
