宽带电力线载波点对点通信性能测试平台设计
Design of point to point communication performance testing platform for broadband power line carrier
摘要
Abstract
In order to test the performances of working frequency , signal power spectral density , anti-jamming capa-bility, noise immunity and anti-impedance changes for low voltage broadband power line carrier communication unit under the requirements of Q/GDW 1379.4-2013 technical specification and offer data reference , scheme basis to grid company to construct remote metering system for broadband power line carrier , a point to point communication per-formance testing platform is formed according to the characteristics of broadband power-line carrier .Three level cas-cade power filter with double SMA terminals are adopted which can insulate the influence on the communication per -formance for broadband carrier communication unit caused by harmonic , pulse signal and power-line background noise .As a consequence , the testing platform mentioned above can fully simulate the low voltage power line channel , restitute the operational state of site metering pilot and assess the actual usage of carrier communication unit .Experi-mental data certifies that the experiment environment of the testing platform constructed is pure , which can attenuate signal within the bandwidth of 2MHz~30MHz up to 93dB so as to ensure that the tested performance data of broad-band carrier communication unit is stable and reliable .关键词
