Title:
PHOTOVOLTAIC POWER GENERATION SYSTEM AND HARMONIC SUPPRESSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/205303
Kind Code:
A1
Abstract:
The present disclosure provides a photovoltaic power generation system and a harmonic suppression method and apparatus. The harmonic suppression system comprises: a photovoltaic system, an alternating current grid, and a tuning capacitor. The photovoltaic system comprises a photovoltaic cell panel and an inverter, and the inverter is used to convert direct current generated by the photovoltaic cell panel into alternating current. The photovoltaic system is connected to the alternating current grid, and the tuning capacitor is connected to a grid-connecting port of the photovoltaic system. The technical solution connects a tuning capacitor to a grid-connecting port of a photovoltaic system, to alter an original resonant frequency of the photovoltaic system, such that the resonant frequency of the grid is staggered with the harmonic frequency generated by an inverter, so as to suppress harmonic resonance introduced by the inverter.
