Abstract：The power quality of the low voltage distribution network is the key factors of reliability and stability of each device operational. Comparative analysis between a new PQ(power quality) compensation device configuration of load side and typical reactive voltage compensation configuration program is described in this paper. We also calculated the power flow of the entire feeder model and parameters of devices under the load-side configuration program of compensation device and compared with the classical voltage and reactive power regulation configuration program in the classical tradition of voltage and reactive power regulation performance. Theoretical analysis and simulation and experiment results proved the effectiveness of the load-side new device configuration methods and the superiority of application in rural distribution network.
