摘要/Abstract

摘要： 无功补偿器是电网中被广泛应用的重要设备。为研究无功补偿器对电力线通信的影响,通过实际测量无功补偿器在50 Hz~1 MHz范围内的阻抗特性,给出了宽频范围内无功补偿器阻抗变化的规律,针对具体无功补偿器介质材料在高频时的特性进行分析,建立了无功补偿器集总参数高频电路模型和基于端口行为的高频模型。利用传输线理论建立了电力线信道参数-确定性模型,分析了无功补偿器对电力线通信信道传输特性以及容量的影响。结果表明,无功补偿器作为电网中常用的电气设备,对电力线通信有重要影响。

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
