Design of Reactive Power Compensation for Low Voltage Distribution Network Based on Intelligent Control Switch

摘要

Since the standardization of ac power distribution, reactive power compensation has become an essential part of commercial power system operation. This paper will review the history of the development of reactive power compensation strategy, analyze the equipment and methods of reactive power compensation, and discuss the strategy of reactive power compensation in low-voltage distribution network. Under conventional switching control, the switching of capacitors produces voltage transients that are disruptive for some users, and the fixed impedance causes the compensation level to fall below the optimal level. Therefore, the intelligent control switch will be used to calculate the power quality by the single chip microcomputer, control the intelligent switch to switch in the best position, in order to reduce the generated voltage transients, improve the power quality.
