【摘要】：提出了一種基于傳輸線理論的信道容量簡化算法,在高帶寬利用率條件下將信道容量解耦成幾個獨立的部分,分別用于研究傳輸距離、單根分支線對信道容量的影響及分支線之間的耦合效果。通過對無分支結構的電力線信道容量分析,提出了信道容量的簡化算法及其適用條件。將分支線對信道容量的影響,分解成了對分支線長度及所接負載影響的研究,通過對部分典型負載特征的分析,討論信道容量對負載的敏感性。利用統(tǒng)計方法研究了分支之間的耦合效應,當電力網(wǎng)中分支相距較遠時,該耦合效果可以忽略不計,則信道容量可以看作與傳輸距離和分支線數(shù)量呈線性關系。仿真結果表明,該簡化算法與傳統(tǒng)計算方法具有較好的一致性,可用于分析不同網(wǎng)絡結構對電力線傳輸性能的影響和信道容量的快速估計。
[Abstract]:In this paper, a simplified channel capacity algorithm based on transmission line theory is proposed. Under the condition of high bandwidth utilization, the channel capacity is decoupling into several independent parts, which are used to study the influence of transmission distance, single branch line on channel capacity and the coupling effect between branch lines. Based on the analysis of power line channel capacity without branch structure, a simplified algorithm of channel capacity and its applicable conditions are proposed. The influence of branch line on channel capacity is decomposed into the study of branch line length and load. Through the analysis of some typical load characteristics, the sensitivity of channel capacity to load is discussed. The coupling effect between branches is studied by statistical method. When the branches are far apart in the power network, the coupling effect can be ignored, then the channel capacity can be regarded as a linear relationship with the transmission distance and the number of branch lines. The simulation results show that the simplified algorithm is in good agreement with the traditional calculation method and can be used to analyze the influence of different network structures on power line transmission performance and the fast estimation of channel capacity.
