Research and Implementation of a Fast Fault Location Algorithm for Distribution Network Equipment

The new distribution network management system is mainly a system that integrates automation and intelligent data acquisition technology, computer technology and business management system, and manages all aspects of the electric distribution grid. The traditional fault analysis of electric distribution grid equipment is to judge the relative position relationship between the widely distributed switches and segmented switch-gear in the electric distribution grid, which can find out the real location of equipment fault through section analysis. This method has a low degree of automation. Later, through the design and development of intelligent computer programs, feeder terminal components are integrated into the conventionalizing switch in the network, through which the state data of the switch is collected, and then the collected data is transmitted to the central controller, which is identified and analyzed by the computer system. After receiving the collected data, after judgment and analysis, specific instructions are issued to operate the switch accordingly, Isolate the faulty equipment in a specific area to ensure that it does not affect other non faulty areas. In the article, a method of fault identification is proposed, which integrates the geographic location information into the computer program, and then performs signal dispatching through instruction analysis to realize the operation monitoring, data signal acquisition, equipment fault location, load control, etc. of the distribution network equipment.
