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...
