Abstract

The invention discloses a power distribution system capable of intelligent filtering compensation, and the system can accurately and completely carry out the stability discrimination of a power distribution system of an active filtering device, and can change the control structure of the active filtering device into an inner loop structure which just needs to control a current from a conventional double-loop structure of current and voltage control. Therefore, the system is simple in setting of control parameters, is high in dynamic response speed, and is high in robustness.

Description

[0001] Technical field [0002] The invention relates to a power distribution system capable of intelligent filter compensation. Background technique [0003] Power quality is the quality of power in the power system. The ideal electrical energy should be a perfectly symmetrical sine wave. Several factors can cause the waveform to deviate from a symmetrical sine, thus creating power quality problems. Power quality is an organic synthesis of multiple indicators. Although countries around the world have formulated a series of standards for each power quality indicator, these standards used to determine whether a single indicator is qualified or unqualified cannot fully, truly and uniquely reflect the total power. the nature of the quality. [0004] With the gradual increase of power equipment invested in various industries, the harmonic content in the power grid is gradually increasing, such as low-voltage large-capacity rectifiers for electrolysis in the chemical caustic sod...
