摘　　要：本文在分析递推最小二乘算法的基础上，给出了在微机变压器差动保护中采用的实用递推算法。理论分析和仿真结果表明，该算法是具有变数据窗，计算简便，收敛速度快的特点。In this paper the recursive least square algorithm is described and a practical recursive algorithm is used in differential protection of transformer. The test results show that the data-window of the algorithm is variable,the convergence speed is fast and the estimating calculation is very simple.
