摘要

对于配电网低压侧电力线通信网络而言，电力线信道具有未知性、时变性、多样性等特点，在实际应用中存在着通信可靠性较低的问题。而电力线双向工频通信系统(TWACS)具有抗干扰、抗衰减能力强的优势。目前路径搜索信令和数据传输都采用同样的技术传输。路径搜索信令通信可靠性低会严重制约路径接力算法的选择和中继接力的效果。对此，文中在阐述低压配电网电力线载波通信网络拓扑和特征的基础上，提出了一种融合TWACS的电力线载波路径搜索算法。对初始路由表进行优化、参数分析及对比分析，来说明该算法的有效性及优越性。同时，分析了路径搜索算法的抗毁性。从理论上深入归纳、分析和总结了该算法的建模理论。结果表明算法在提高有效性和可靠性等方面优势明显，能够更好地满足配电网中电力线中继传输需求。

Abstract

For the low-voltage side of power line communication network

power line channel has the characteristics of unpredictability

time-varying and diversity

which leads to a low communication reliability problem in practical applications. While two way automatic communication system(TWACS)has the advantages of strong anti-interference and anti-attenuation abilities. Currently path search signaling and data transmission both use the same technology. Search path signaling communication reliability is low

which can severely restrict the path selection algorithm and the effect of relay baton. For this reason

on the basis of network topology and characteristics of power line communication

a PLC path search algorithm merged with TWACS is proposed. By means of the initial routing table optimization

parameter analysis and comparative analysis

the effectiveness and superiority of the algorithm can be illustrated. Meanwhile

the anti-destruction ability of the path search algorithm is analyzed. The modeling theory of this algorithm is summarized in depth. Results show that the algorithm has improved the effectiveness and reliability to better meet the demand of the power line distribution network relay transmission.
