摘要

在中压配网信道模型基础上

重点分析配电线路、配电变压器、无功补偿装置及中压开闭所等一次设备对载波信号传输衰耗的影响规律

为高速率窄带电力线载波通信（NB-PLC）在中压配网中的实用化提供必要的参考依据。研究结果表明:电压衰减的幅度随着分支线长度、分支线数目及配电变压器数量的增加而增大

而与主干线路长度基本无关;架空和电缆混联线路引起折射衰耗大

而中压开闭所对电压传输衰落的影响可忽略不计;无功补偿装置经一定长度电缆接入系统

则补偿的位置、容量的增加并不会引起电压衰落的大幅度增加。

Abstract

In this paper

the law of influence of such primary equipment as line

distribution transformer

reactive power device and MV substation is selectively analyzed on the basis of MV distribution network channel module

which provides necessary evidence for the application of high rate narrow band PLC in the MV distribution network. It is shown by the study result that the magnitude of voltage decay increases with the increase of the length of branch line

number of branch line and the number of distribution transformer and has basically nothing to do with the length of trunk line. The mixed line of overhead and cable can cause big refraction attenuation

but the influence of MV substation on the voltage transmission decay is neglected. The reactive power device is connected to the system through a definite length of cable and the increase of compensation position and capacity will not lead to significant increase of voltage decline.
