Abstract
This paper describes a new algorithm for measuring the frequency in electric power systems. The algorithm is based on the Least Error Squares (LES) technique and uses digitized samples of voltage at a relay location. The algorithm uses one matrix with constant coefficients which can be previously calculated. It was successfully tested using computer simulated signals and using signals obtained through laboratory tests and field measurements. The test results demonstrate the ability of this algorithm to estimate voltage and frequency with acceptable accuracy.
