用于动态条件下同步相量测量的复带通滤波算法
A Complex Bandpass Filtering Algorithm for Synchronized Phasor Measurement Under Dynamic Conditions
摘要
Abstract
In order to make synchronized phasor measurement meet the accuracy requirements under dynamic conditions, a complex bandpass-filtering algorithm was proposed. Its measurement bandwidth and group delay corresponding to various phasor-uploading rates were provided to make the method be able to output amplitude modulated components without distortion, restrain the out-of-band interference and have short dynamic response time. Based on acquired phase angles, the weighted least squares （WLS） was applied, instead of traditional derivation operation, to improve frequency measurement robustness. Simulation and field test results show that the proposed method complies with the level 1 of IEEE Standard C37.118-2005 under steady state, and has high accuracy under dynamic conditions. In addition, the method has small amount of computation and is fast enough for online application.关键词
