A TECHNIQUE FOR DIGITAL RELAYS TO MEASURE FREQUENCY AND ITS RATE OF CHANGE

Several techniques for measuring frequency at a power system bus have been proposed for use in digital relays. This paper presents a new technique for measuring frequency and demonstrates a procedure for calculating the rate of change of frequency. The effect of noise in the input signal is examined. The paper also evaluates the performance of the proposed algorithm using simulated data and data recorded in the laboratory.
