FAULT LOCATION IN TRANSMISSION-LINES

The paper describes a new concept for analysing digital dynamic record s of transmission line faults and introduces a transmission line fault location system. Three functional blocks control transmission line fa ult identification. The first one controls adaptive filtering; the sec ond block controls the evaluation of parameters; the third one control s revision of a priori information according to service data. The conc ept considered is developed as a program package to be used together w ith transmission line fault recorders. Results of processing line faul ts in the Chuvashenergo and Saratovenergo networks are given. (C) 1997 Elsevier Science Ltd. All rights reserved.
