摘要：
A comparative study of two well-known online power system frequency estimation methods is presented in this paper. These methods are least squares error (LES) and least squares new approach (LS). The performance of the frequency estimation methods is tested in laboratory with an Advantech data acquisition system and Matlab tool. The performance of LS online frequency estimation method with and without filtering is examined along with LES method. The experimental results show that the frequency measurement method using LES could be the optimal frequency measurement method, and thus can be applied to frequency measurement apparatus.
