摘要
Abstract
Recursive Fourier algorithm is a commonly used digital signal processing algorithm for protection relays.Its characteristic is to use the last calculation result to calculate the current result.Its calculation efficiency is very high.However,the recursive algorithm has a memory effect.Errors caused by accidental factors will be kept and be difficult to detect,bringing hidden dangers to the operation of the protection device.In this paper,a fault-tolerant mechanism suitable for recursive algorithm is proposed to eliminate the memory effect and prevent irrecoverable calculation deviation caused by occasional or accumulated errors,thus effectively preventing such problems from causing misoperation or failure of protection devices.关键词
