Abstract:
Aiming at the action situation of the compositevoltage memory overcurrent protection of the selfshunt 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 overcurrent protection was analyzed. The principles of sampled value emendation and the voltage tracking overcurrent 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
