Zusammenfassung:The novel hybrid method of the Discrete Fourier Transform (DFT) and the Enhanced Phase-Locked Loop (EPLL) has been presented. The original well-known methods and the Hybrid method have been analysed and tested in several simulations and experiments. The methods are implemented on the Digital Signal Processor and compared in a real time power quality application. Although it requires a bit higher computational effort, the Hybrid method compared to original methods shows advantages for on-line harmonic analysis.
