Abstract

The designed frequency compensator is proposed to make the estimation of amplitude of fundamental frequency immune to frequency variation. The designed method which has a simple structure and low calculation burden is proper to apply digital protective relay. The results of experimental demonstrate that the frequency compensator has good performance to the estimation of amplitude of fundamental frequency against frequency variation.
