Analysis on influence of voltage frequency on compositevoltage memory overcurrent protection

Abstract

Abstract:

Aiming at the action situation of the compositevoltage memory overcurrent protection of the selfshunt excitation generator set with medium or

small capacity during the power system load rejection caused by remote fault, the influence of the variation of the voltage frequency on the composite

voltage memory overcurrent protection was analyzed. The principles of sampled value emendation and the voltage tracking overcurrent protection were

introduced, and relevant solution was proposed.

Key words: self-shunt excitation generator, composite-voltage memory over-current protection, voltage tracking over-current protection, sampled value emendation, frequency
