摘要
电力线载波通信技术是电力系统中应用广泛的重要通信手段。建立网络中组成元件的阻抗模型是研究信道传输特性的关键和前提。对传统配电网中配电变压器及其低压侧负荷、架空线路和埋地电缆以及在线用电设备的阻抗模型进行了综述。介绍了各类元件模型的建模技术,详细分析了各类阻抗模型的优缺点和适用范围。结合智能电网的特点,讨论了中压智能电网应用电力载波通信技术时元件阻抗建模需要解决的新问题和关键技术。
Power line communication （PLC） technology is an important communication method which has been widely used in power system. Establishment of the component impedance model in the network is a key issue for the research of channel transmission characteristic. This paper gives an overview of the impedance modeling of distribution transformers and its low-voltage loads, overhead lines/underground cables, and online electrical equipments in traditional distribution network. The advantages and disadvantages of various impedance modeling technologies and their application scopes are analyzed in detail. Finally, the component impedance modeling issues and the associated key technologies that need to be resolved when applying the power line carrier communication technology in medium voltage smart grid are discussed based on the characteristics of smart grid.
