【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 power line communication network on the low-voltage side of the distribution network, the power line channel is characterized by unknown, time-varying and diverse. In the practical application, there is the problem of low reliability of communication, and the power line bidirectional power frequency communication system (TWACS) has anti-interference. At present, the same technology is used for both path search signaling and data transmission. The low reliability of path search signaling communication will seriously restrict the selection of path relay algorithm and the effect of relay relay. On the basis of describing the topology and characteristics of power line carrier communication network in low voltage distribution network, a power line carrier path search algorithm based on TWACS is proposed in this paper. The initial routing table is optimized, parameter analysis and contrast analysis are carried out. At the same time, the invulnerability of the path search algorithm is analyzed. The modeling theory of the algorithm is analyzed and summarized. The results show that the algorithm has obvious advantages in improving efficiency and reliability and can better meet the needs of power line relay transmission in distribution network.
