How to Reduce Errors of Distance Fault Locating Algorithms

Wiszniewski, A (Wroclaw University of Technology, Poland)

1981-12-12

Abstract: Distance fault locating digital algorithms are often based on the processing of fundamental components which are contained in the currents and Voltages. If the extraction of these components is done by means of correlating the signals with sine/cosine functions of the fundamental frequency, and the data window is shorter then one period, the presence of aperiodic components in the signals gives rise to large errors. The paper suggests, that to reduce the errors the signals ought to be correlated with sine/cosine functions which have periods equal to the data window length.
