The paper describes the development of a rapid-response frequency-tracking instrument for use in the control of power systems. The microprocessor-based instrument employs a quasi-rate-of-change of frequency algorithm to minimise the delay in detecting abnormal frequency deviations without introducing erroneous fault indications, and is intended for use in the control of a flywheel energy storage scheme to replace conventional spinning reserve in power systems.
