Descrição: This study presents a methodology for compressing power system (PS) signals based on the Discrete Hartley Transform (DHT) and develops a computationally efficient approach for calculating power quality (PQ) parameters. Several algorithms are proposed for dynamic bit allocation for coefficient quantization of the DHT. The proposed algorithm was trialed on a real-world signal database and produced better results than those obtained using wavelet transforms. Several scenarios are investigated, and the comparative results are shown.
