Abstract

The invention discloses a dynamic reactive power compensation controller based on instant sequence component power. The dynamic reactive power compensation controller comprises a hardware portion and a software portion. The hardware portion is mainly composed of a digital signal processing module, an alternating current sampling module, a serial communication module, a man-machine interface module and the like. The software portion is mainly composed of an instant sequence component power algorithm, a capacitor switching control algorithm and the like. By means of the dynamic reactive power compensation controller, low-cost large-capacity reactive power fast compensation is achieved. The instant sequence component power algorithm can achieve self-adaptation three-phase co-phase or split-phase fast mixed compensation on balanced or unbalanced load.

Description

technical field

[0001] The invention is designed based on the instantaneous sequence component power algorithm according to the reactive power requirements of the distribution network or users, and has the characteristics of modularization, networking, and intelligence, and can realize self-adaptive three-phase power distribution for balanced or unbalanced loads. The invention relates to a quasi-real-time dynamic reactive power compensation controller for phase-co-phase or phase-separate mixed compensation, which belongs to the technical field of power quality. Background technique

[0002] With the increasing number of unbalanced and impactful industrial electrical equipment such as AC electric arc furnaces and rolling mills, many power quality problems such as low power factor, voltage fluctuation and flicker, and unbalanced three-phase voltage and current have arisen. Conventional low-voltage reactive power compensation devices are generally composed of controllers, paral...
