Power System Frequency and ROCOF Measurement by Means of Electronic Instrument

Daniel Belega, Gabriel Găspăresc

Abstract

In this paper the accuracy of the power system frequency measurement achieved by means of two commonly used electronic instruments, which are a universal counter and a bench top digital multimeter, are investigated under steady-state conditions in the case of synthetized and real-life power system signals. Moreover, the accuracy of the Rate-Of-Change Of Frequency (ROCOF) estimates achieved by means of the frequency measurements is analyzed. The results obtained by both instruments are compared with each other. In addition, from the achieved measurements some remarks are drawn.
