| Popis: | Frequency estimation is an important power quality parameter that is also useful for the protection and control of distributed generators. This paper proposes a robust three-phase distribution system frequency estimation algorithm based on the widely linear complex least mean square using a variable step-size to provide accurate frequency estimation and fast convergence during islanding of distributed generation (DG) and faults. The performance of the proposed method was evaluated in islanding events of DG. Besides, unbalanced analytical signals in amplitude and phase were evaluated as well as the impacts of the sampling rate and noise. The proposed algorithm was compared to other least mean square-based methods and good results were achieved. |
