Description

Technical Field

[0001] The present invention relates to the technical field of power grid facilities, and in particular to a hybrid power quality compensation device. Background Art

[0002] Power quality refers to the quality of electric energy in the power system. Ideal electric energy should be a perfectly symmetrical sine wave. Some factors will cause the waveform to deviate from the symmetrical sine wave, which will cause power quality problems. On the one hand, we study what factors will cause power quality problems, and on the other hand, we study what problems these factors will cause. Finally, we need to study how to eliminate these factors so that the electric energy can be as close to the sine wave as possible. Measures to improve power quality involve a wide range of aspects, mainly including reactive power compensation, harmonic suppression, voltage fluctuation and flicker reduction, and three-phase imbalance. Devices used for reactive power compensation and harmonic control include: passive power filters, which have both reactive power compensation and voltage regulation functions. Generally, they are specially designed according to the parameters of the harmonic source, the electrical characteristics of the installation point, and user requirements; static VAR compensation devices (SVC) devices are important devices for comprehensive control of voltage fluctuations and flickers, harmonics, and voltage imbalance. Active power filter (APF), APF is a new type of power electronic device that dynamically suppresses harmonics and compensates reactive power. It can compensate for harmonics and reactive currents with changing frequencies and amplitudes, and is mainly used in distribution systems.
