| Popis: | This paper compares the performance of two algorithms for fundamental frequency measurement. Here, the performance of these algorithms will be evaluated during a transient situation generated by the disconnection of the distributed generation (DG) of the rest of the main distribution systems. This situation is known as islanding condition of the DG. These evaluated algorithms are based on techniques such as (a) method based on discrete Fourier Transform (DFT) and (b) Prony Fourier algorithm. The methodology for evaluation of performance was obtained by simulation of experimental cases of 32 kV distribution system in islanding condition. The islanding events were made varying the distributed synchronous generator nominal power. Here, the distribution system is connected to a synchronous generator of 30 MVA. Therefore, the performance of frequency estimation methods evaluated in islanding condition is based on statistical errors, relative error. The DFT-based estimator showed a better transient behavior in all the analyzed cases in comparison with the other evaluated algorithm |
