Parameter identification algorithm for fault location using one terminal data based on frequency domain

Fault locationtechniques for power systemhavebeen investigated for many years.The quicker theaccurate location of a fault,the faster the electricpower restoration of service.The fault location techniques can be classifiedintot wo classes:one uses the data fromone ter minalof trans mission line;the other uses the data fromboth ter minals.The accuracy of one ter minal faultlocators is affected by the assumptions about thefault resistance,the source i mpedance,and the cur-rent flowinto fault from…
