Research On Fault Restoration System For Local High-voltage Distribution System

It is described in this paper that a practical fault restoration system is developed forlocal high-voltage distribution power system. The main content includes: Make a pattern of the fault distribution network based on verge-switch. Describethe distribution system as combination of sub-systems and verge-switch .The newpattern predigest the search process. Set a knowledge express of electrical equipments .finish network analysis of thedistribution system. Based on verge-switch pattern, heuristic algorithm, consider field experience andrestriction, select most suitable approach for island-restoration and overload-dealing. Design and realize a practical fault restoration system for real-time and faultpreview use, include system function, flow and interface with other applications of EMS.For application of fault preview, the action of auto-standby system is considered. Asimple simulation function is designed for test. Based on Lanzhou local distribution network, some functions of fault restorationsystem is tested, and the result is satisfied.
