Abstract

A new method of optimizing the Underfrequency load shedding (UFLS) has been developed in the paper. The main idea is that on the basis of the on-line measurement of the load frequency regulation factor, the load with smaller frequency regulation factor is cut off earlier than those with larger frequency regulation factor, therefore the power from sources will be much decreased and the power balance will be achieved more quickly in the transient process. The realization method and digital simulation of the proposed scheme have been presented t.
