Synthesized filtering algorithm for microprocessor based protection
International Journal of Electrical Power & Energy Systems, 1994 Abstract Many algorithms have been proposed for a microprocessor based on-line digital control and protection systems. Some algorithms are only accurate for fundamental frequency components, while others are suitable for signals which contain substantial transient components due to short-circuit transients.
