Abstract

Abstract: The frequency measurement is of decisive significance in electric power system stability control. The limitations of the traditional frequency measurement method were analyzed. And based on the wide area measurement system, a new system frequency measurement method was proposed, in which the units rotate speed of the system was realtime measured, and then the frequency of system inertia center was calculated out.

Key words: power system, frequency measurement, inertia center, wide area measurement system
