Research and Application of Three-phase Imbalance Control Strategy in Low Voltage Distribution Network

Abstract

This article first analyzes the causes of the three-phase unbalance in the distribution network in detail, and then uses the commutation switch device and the SVG-based three-phase unbalance adjustment device to manage the three-phase unbalance problem in the low-voltage distribution network. The effectiveness of the device is verified through practical applications. After further comparing the advantages and disadvantages of different balance treatment devices and their treatment effects, a treatment method combining SVG + commutation switch technology is proposed. Through practical application comparison, this method can achieve the optimal adjustment of the distribution network balance.
