Abstract

In order to achieve the application of AC chopping reactive power compensator in the distribution network with higher voltage

in this paper

the reactive power compensation technology proposal for the unit-series AC chopping circuit based on the traditional AC chopping circuit principle is proposed. The topological structure of unit series reactive power compensator is designed

the reactive power and harmonic compensation principle of the unit series AC chopping circuit is introduced and the control proposal of the reactive power

harmonic compensation and voltage balance based on synchronous rotation coordinate is designed. The unit series AC chopping reactive power compensator

compare to the traditional AC chopping reactive power compensator

reduces voltage stress of the switch tube through the series unit

has reliable operation and high voltage withstand.Finally

both feasibility and effectiveness of the new device is verified by the simulation.
