The use of photovoltaic power generation systems is increasing all around the world. However, photovoltaic systems use inverters and other electronics to convert and control DC power from panels to AC power. This may lead to increased power losses, decreased efficiency and power factor, overheating due to higher parasitic currents, and possible damages of the devices designed to work with smoot…
An active power filter (APF)based on digital signal processor (DSP) and complicated programming logic component (CPLD) is designed in this paper. Solft and hard wares are introduced and the simulation experiment to compensate the reactive power and harmonics in three-phase four-wires system is done. By using Matlab. simulation model is build for the device. The result shows that this model can …
Filter detuning strongly affects the filter's size and operating performance. Partial resonance is recommended to raise the filtering efficiency of a single-tuned filter at the worst point in the detuning range. This paper presents a new way to obtain the optimal tuning frequency of a single-tuned harmonic filter in order to control harmonic currents to the allowable value with a minimum filter…
