Abstract

The work is devoted to research of the characteristics of Broadband over Power Lines (BPL) transmission systems (TS) when working on domestic house electrical wiring networks (HEWN). The object of research is the component of domestic electrical wiring network (HEWN) – branch. The influence of the branch load resistance on attenuation and data transmission rate acros HEWN fragment with one branch in the cases of the idle and short type of load, the load with active and reactive resistance type in the case of traditional orthogonal harmonic signals and generalized class orthogonal harmonic signals used in BPL TS was reviewed previously. The influence of number and position of active and reactive character load of branch on attenuation, phase and data transmission rate acros HEWN fragment in the case of traditional orthogonal harmonic signals on BPL TS uses is researched in the paper. Calculations are carried out and the results of research of frequency characteristics of attenuation, phase and data transmission rate acros HEWN fragment, formed with widely used in Ukraine PPV type wire (the cross-sectional area of the conductor is 2,5 mm2), in the range of 2 MHz to 30 MHz are given. The research of dependence between BPL TS data transmission rate acros HEWN fragment (in the case of 25ºMHz-PB frequency plan uses) and number and position of the load branches in the case of the idle type of load, the load with active and reactive resistance type (R, L, C) that connected to the poles of the load on the branch is researched in the paper. A comparison of the data transmission rate acros HEWN fragment for different numbers and variants of the position of the loaded branches that poles of which connected to the loads of different types (idle, R, L, C) was made.
