| 摘 要： | 对解微分方程算法作了改进,方法是通过对传统微分方程算法在有限时段上进行积分变换,借助积分减少高频分量的影响。通过数字仿真计算验证了改进后算法的优良估计性能,将之与基于微分方程模型的最小二乘法、全波傅里叶算法作了比较。并根据各算法的估计性能特点,提出了一种具有反时限特性的距离保护算法的实现方案。

| Abstract: | The algorithm for differential equation solution is improved,which adds integral transform in finite period to it to lessen the influence of high-frequency component.The digital simulative results show its good performance of estimation.It is compared with differential equation model-based least square algorithm and all-ware Fourier algorithm.According to the characteristics of different algorithms,an implementation scheme of distance protection with inverse time charac-teristic is brought forward. |
