This paper deals with harmonics and reactive power compensation method by grid-connected Photovoltaic (PV) generation system. The experiment is carried out on the proposed single-stage grid-connected PV generation system, and controlled by digital signal processor TMS320F2812. The experimental results include converter operating features either as active power filter or static synchronous compensator...
As one of the most effective methods to inhibit electric power grid harmonics, the technology of Active Power Filter (APF) has been a key subject in the field of power quality control. Currently, research on APF mainly focuses on topology structure and control strategy. A novel topological structure of APF in alpha-beta coordinate is presented based on transformation of three phase static A-B-C coordinate...
The method of harmonious detecting is introduced about PV grid connected generation, and the technique is realized to harmonious synchronous sampling based on PLL circuit of hardware, in order that the error is eliminated for non-synchronous sampling at all. It is used to analyze the harmonic of PV system for FFT algorithm based on B-H window function and interpolation, and the error is minished by...
With the continuous development of water-saving irrigation, agricultural productpsilas deep process, greenhouse control in the agriculture, more and more variable frequency equipments, rectifier devices and other power electronic equipments have been used. But owing to the use of these equipments, harmonic pollution problem in power grid is more serious. Active filter is an effective method to the...
