Study on the Electrical Power Fault Recorder Integrated Analysis & Application System

This paper introduces an electric power fault recorder integrated analyzing & application system, which interconnects digital fault recorders of several substations and power houses that are widespread in Jiangxi province of China and has the fault information gathered, processed, transmitted, shared and utilized automatically and effectively. A method based on the Newton iterative algorithm for precise fault data analysis was introduced into this system. In addition to realize the conventional analysis functions that are provided by similar systems, this system realizes extended functions of flexible protection action judgment. Besides, functions of formula editor and protective relaying testing simulation have been added and provide a novel approach for the comprehensive fault analysis applications. This system is now running steadily at the dispatch center of Jiangxi Province. The good results obtained reveal the superiority and effectiveness of this system.
