Abstract

The invention discloses a master-slave fault self-healing control method and system for a power distribution network. The method comprises the steps of determining a master-slave fault self-healing control architecture of the power distribution network, adopting distributed slave control, controlling an interconnection switch to act, completing power supply recovery of a power-losing area, adopting centralized master control, solving an optimal combination of the interconnection switch and a section switch of the power distribution network, and adjusting the operation state of the power distribution network to recover to the optimal state; according to the measurement data of the power distribution network measurement unit, initializing a power distribution network topological structure and electrical quantity parameters after the fault branch is removed, wherein the electrical quantity parameters comprise node voltage, branch current and load power; executing a power distribution network fault self-healing slave control scheme, and formulating a to-be-recovered power distribution network interconnection switch action scheme; and executing a power distribution network fault self-healing control master control scheme, calculating an optimal combination of all section switches and interconnection switches of the network, and optimizing the running state of the power distribution network.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a master-slave fault self-healing control method and system for a distribution network. Background technique [0002] The distribution network carries the heavy responsibility of delivering stable electric energy for production and life. With the continuous improvement of urban development, the power supply load density of distribution network has increased significantly, and the variety of loads has strong diversity; the requirements for power quality of sensitive loads and important loads are increasing, and the safety and reliability of distribution network are particularly important. However, the structure of the distribution network is complex, and its reliability is restricted by many factors such as components and the environment, so faults are inevitable. Moreover, the distribution network is usually a radial passive structure, and each node has only one ...
