摘要
为满足载波信号在中压配网电缆线路的耦合通信要求,需要高耦合效率的卡式电感耦合器。提出一种中压配网载波通信卡式电感耦合器耦合模型,并对其耦合效率进行了分析。首先在卡式电感耦合器结构型式及电缆线路结构特征基础上,分析卡式电感耦合器的耦合机理。然后结合罗氏线圈与松耦合变压器模型,推导卡式电感耦合器的耦合数学模型,修正卡式电感耦合器互感系数。并利用ansoft电磁软件搭建仿真模型,验证所推导的卡式电感耦合器耦合数学模型的正确性。最后利用耦合器数学模型及仿真模型,分析卡式电感耦合器不同影响因子:耦合器磁环气隙、磁环相对磁导率、绕组匝数以及耦合器骨架尺寸对电缆侧电压耦合效率的影响。仿真结果与计算结果均表明,所提耦合器数学模型能够准确地反映耦合器的耦合情况,为电力线载波技术在智能配电网中的实用化提供了较好的分析方法和理论依据。
In order to meet the coupling communication requirements of the carrier signal in the medium voltage distribution network cable line, a clamp inductive coupler with a high coupling efficiency is required. This paper proposes a clamp inductive coupler coupling model of medium-voltage distribution network carrier and analyzes its coupling efficiency. Firstly, the coupling mechanism of the clamp inductive coupler is analyzed on the basis of the structure type of the clamp inductive coupler and the structure of the cable circuit; then, the coupled mathematical model of the clamp inductive coupler is deduced in combination with the Rogowski coil and the loose-coupling transformer model, and the mutual inductance is modified. The mutual inductance coupler is used to construct a simulation using ansoft electromagnetic software to verify the correctness of the deduced coupled mathematical model of the clamp inductive coupler. Finally, the different effects of the clamp inductive coupler are analyzed using the coupler mathematical model and simulation model. The effect of the air gap of the coupler ring, the relative permeability of the ring, the number of winding turns, and the frame size of the coupler on the voltage coupling efficiency at the cable side is analyzed. The simulation results and calculation results show that the mathematical model of the coupled coupler can accurately reflect the coupled state of the coupler, which provides a good analysis method and theoretical basis for the practical application of the power line carrier technology in the intelligent distribution network.
