Özet:

 

Voltage sags in the electric power system are mostly due to  faults in the power system.  Voltage sag is characterized by its  magnitude (the retained voltage), phase-angle jump, unbalance in the  sag in the three phases, and duration.  Type of transformers in the  electrical system is the important parameter influencing the  characteristic of sag at the node where sensitive loads are connected.  For sensitive loads it is necessary to estimate how many times in a  year the voltage at their terminal will experience sag to avoid  tripping of operation.  In this paper the effect of transformer on  stochastic estimation of voltage sag is studied.  Several stochastic  methods for the estimation of number of sags have been developed in  recent years.  Various methods of sag prediction require lengthy  programming or calculations.  In the present work the PSCAD/EMTDC  software package is used to estimate number of sags assuming uniform  distribution of faults along the lines.
