Abstract

Abstract: Reactive power compensator is an important equipment which is widely used in power system. To study the influences of reactive power compensator on power line communication (PLC), the impedance characteristics of the reactive power compensator in the range of 50 Hz~1 MHz were measured, and the variation rule of the reactive power compensator impedance was proposed. The high frequency characteristics of dielectric materials in reactive power compensator were analyzed. And the high-frequency lumped parameter model and high-frequency two-port network model of reactive power compensator were proposed. The power line parameters-deterministic model was established based on the transmission line theory. The reactive power compensator effects on the transmission characteristics and capacity of PLC channel were further investigated. The results show that, the reactive power compensator as a prevalent electrical equipment in the power system has important influences on the PLC.

Key words: power line communication, reactive power compensator, high frequency model, MATLAB simulation, channel characteristics
