摘要
En 中文
The main focus of this work is power quality issues such as voltage and frequency fluctuation under load variation, source current distortion and power mismatch between utility and load in a single-phase SEIG-based isolated system. Therefore, this paper addressed the said problems using momentum least mean square control algorithm for single-phase SEIG working in stand-alone operation. The coordinated operation of battery energy storage system and dump load controller is also carried out for better battery performance. The features of this algorithm are its capability to extract desired signal from a fixed amplitude, non-stationary, linear frequency and variable amplitude sinusoidal signals in both noise-free and noisy conditions. The reference current tracking performance is improved by estimating the incremental convergence rate and the momentum term scaled by the factor alpha in the LMS-based algorithm. Due to the presence of scaling factor with the various weights from preceding two iterations, it is certainly convergent more rapidly. Moreover, it has promised better reliability in reckless atmosphere. This control is verified by computer simulations. The entire system is developed in MATLAB/SIMULINK environment followed by experimental validation of control algorithm.
