Research on Harmonic Current Detection Method Background of Microgrid

摘要：

　　Due to the type of power in the microgrid are numerous, intermittent and randomness, and is accompanied by a large number of inverters , so the power quality problems such as harmonics are produced. For this resort, this paper presents a new power quality detection method, this method used the Chain Mixed Morphological Filter (CMMF) instead of the Low-Pass Filter (LPF) in the conventional ip—iq detection method based on the instantaneous reactive power theory, it maked many Mixed Morphological Filters gettd serially concatenated, and rational choosed the shape and length of the structural elements of each Mixed Morphological Filter, to achieve the best detection.Simulation results show that, this method can be fast and accurate detection of harmonic signals.
