Abstract

An investigation is made of a particular microprocessor board arrangement which serves as the base for a variety of power system protection devices. It calculates the first 15 harmonic components of up to 9 nominal power frequency inputs and updates these harmonics every 2 ms. It dynamically tracks the fundamental frequency and alters the sampling rate to remain at 32 per fundamental cycle. The harmonic components are available for use in a variety of protection algorithms and typical examples are given
