Alongside the growth of power supply in 220kV network in Anhui province (jn China) .intermediate substations were set up on several long transmission lines, thus breaking the whole line into shorter ones. Correspondingly, the number of double circuit lines increased.with regard to power line carrier communication, the number of broad band width line traps and coupling filters installed at terminals and intermediate bridging circuits should also increase. As a result, the quality of carrier channel declined. In bad weather condition, the PLC communication may be interrupted.This paper makes a survey of the causes of the increase of Overall attenuation of PLC channel due to the change of line configuration, For this purpose, the following factors are analyzed in delail:(1) the mismatch between input and load impedances dut to the shortening of direct transmission distance, (2) terminal states (in overhaul or cold stand by vs.in operation); (3) the operation mode of double-circuit lines; (4)the effect of broad baudwidth line traps and coupling filter.

随着220千伏电网供电密度的扩大,在一些长距离的输电线路上多处开断,新建了一些中间变电所,线路距离变短。平行(或同杆)架设的输电线路也相应增多。在网络结线复杂的220千伏线路上组建载波通道,终端和中间桥路所采用的宽频结合加工设备(指阻波器和结合滤波器)数量随之增多。由电网结线变化所产生的电气短线、线路终端状态、平行线路运行方式的变化和宽频结合加工设备附加衰耗对载波通道总衰耗的影响,致使部分电路的实际通道衰耗远远超过了计算值。造成电路质量和运行可靠性下降。在恶劣的气候条件下,甚至会中断通信电路。针对这种情况,我们结合近年来的220千伏线路载波通道的运行实践,对电网结线变化所造成的载波通道总衰耗普遍增大的几个因素进行了分析。

This paper discussed the uniform under-sampling of multiple bandpass signals in digital receiver. For these multiple real or complex bandpass signals having arbitrary band position and bandwidth, the acceptable sampling rate has been given. Using this sampling rate to sample the input bandpass signal, an efficient data compression can be gotten. In the same time using band pass filter, these multiple bandpass signals can be transferred to the lower frequency. Finally, an example is given to show the correctness...
