Özet:

 

This paper deals with non-pilot distance protection of a  double-circuit transmission line.  Negative impact of the reactance  effect, appearing in measuring a fault loop impedance, on operation of  the relay is discussed.  An adaptive algorithm allowing one to prevent  the relay from mis- or mal-operation caused by the reactance effect is  introduced.  The algorithm is designed for a standard availability of  measurements from one end of the double-circuit line, i.e. when  three-phase voltage and current from the faulted line circuit, and  additionally zero-sequence current from the healthy line circuit, are  provided as the relay input signals.  The algorithm is based on  changing the position of the distance relay characteristic in such a  way that the reactance effect is effectively compensated for.  For  this purpose the shift vector is determined in on-line relatively  simple calculations.  The delivered adaptive algorithm has been tested  using current and voltage signals obtained from simulation of varies  faults using the ATP-EMTP software program.  Selected results of the  evaluation are presented.
