Low-voltage distribution power quality control experimental system

The invention discloses a low-voltage distribution power quality control experimental system comprising a high-voltage electric energy gauge table, a distribution transform transformer, a low-voltageelectric energy gauge table, and a low-voltage power quality control device. The low-voltage power quality control device consists of a filter device for eliminating intermediate harmonic waves in a power transmission line, an intelligent capacitor for carrying out reactive power compensation on the power transmission line, a feedback device for compensating power of a phase with a lower load in the power transmission line to a phase with a larger load in the power transmission line, a data acquisition testing device for collecting a power quality parameter in the power transmission line, andARM controller for controlling the filter device, the intelligent capacitor, and the feedback device based on data collected by the data acquisition testing device. The filter device is connected to the power transmission line
