摘要
本文重点就递推最小二乘算法的滤波特性进行了分析,并从频城的角度对状态量的选择问题进行了讨论,给出了便于在微机距离保护中采用的实用递推算法。理论分析和仿真计算表明,该算法计算简便、收敛速度快,其具有的变数据窗特点可有效实现保护的反时限动作特性。
In this paper, a recursive algorithm based on the least square principle is described, and the problem about the selection of the state model is also discussed. The test results show that the convergence speed of the algorithm is fast and the estimating calculation is very simple. In addition, the algorithm due to its variable data-window would help to constitute a new impedance relay with adaptive reach-speed characteristic.
