摘要：数字式继电保护反时限特性的实现方法，本发明属于继电保护装置过电流保护方法。它克服了现有的数字式继电保护反时限特性实现方法对保护装置的运算速度要求高、实时计算量大、难于实现等缺陷。其步骤是：继电保护装置上电；读取用户设置参数，将变量X₁、变量X₂置零；计算(Kτ_pI^r_p)/△t并将其赋给变量X₁；间隔时间Δt采集电流I_j；计算I_j^r并将其累加到变量X₂；将I_p^r累加到变量X₁；判断变量X₂的值是否大于等于变量X₁的值；若是，则反时限保护动作，否则重新开始采样、计算、比较、判断。本方法将与实时电流无关的判据参量放在实时采样计算前进行计算，实时计算量小，降低了对继电保护装置运算速度的要求，且能全面地反映被保护对象的电流/时间特性，判断准确、使用方便，具有较大推广价值。
