Paper Title:
The Research on High-Voltage Transmission Line Relay Protection Setting Related to OLTC Anti-Icing
  Abstract

In order to make high-voltage transmission line anti-icing without interrupting power supply, OLTC anti-icing devices can be used for reducing the line voltage and increasing operating current to undermine the conditions of icing formation. The relevant relay setting values of the anti-icing line needs to be modified accordingly. In this paper, the research on how to reset the value of the 110kV and 220kV lines had been done after the OLTC equipment was implemented, and the principle of relay protection setting related to the change of line operating voltage and current had been given. A digital simulation of an area which encountered the icing disaster in 2008 had been done and the results shows that the reset relay protection setting of relevant relay protection is reasonable.
