摘要
为抑制谐振接地系统对地电容中的工频信号和其它谐波成分,分析和比较了基于LMS和RLS算法的自适应滤波算法。对两种算法滤波理论、性能及算法进行仿真研究表明:RLS算法提高了滤波的稳定性、快速性和精确性,优于其它自适应算法。
The adaptive filtering algorithms-least-squares （RLS） algorithm and least-mean-squares （LMS） algorithm were studied and compared in order to suppress the power frequency signal： and other harmonic components in earth＂ capacitance of resonant grounded system. The results from the study of their theories, performances and simulations showed that the RLS algorithm improved stability, speed and accuracy of filtering which is superior to the other adaptive algorithm.
