英文摘要：

An improved adaptive generalized morphological filter is proposed. With respect to the different types of noise possibly encountered during power system signal acquisition, by means of digital simulation the influence of the variations of both amplitude and length of structural elements on filtering effect of improved adaptive generalized morphological filter is researched in detail. Simulation results show that various noise encountered during power system signal acquisition can be effectively suppressed by the proposed improved adaptive generalized morphological filter, and the filtering effect is satisfied.
