针对现有技术中电力通信传输网传输速率低、组网配置不高的问题,提出了基于光传输OTN技术的电力通信传输网络优化方案,设计出具有监控、配线、复用、网管和保护等多种功能的OXC模块,并应用纯光交叉矩阵,提高了网络通信信息承载量和性能稳定度。该研究在OXC模块中还融入了迭代分块约束注水算法,有效地将电力通信传输网络系统中不同信道内的子载波平均分配成诸多子通信模块,实现通信的均衡处理,提高了电力通信传输网运行的效率。试验表明,该研究方法提高了电力通信网络资源的分配能力。

In order to improve the problems of low transmission rate and low network configuration of power communication transmission network in the prior art,an optimization plan for power communication transmission network based on optical transmission OTN technology is proposed,and the design of OXC modules which has monitoring,wiring,multiplexing,network management and protection,and other multiple functions,and the application of pure optical cross matrix improves the information carrying capacity and performance stability of network communication.This research also incorporates an iterative sub-block water-filling algorithm in the OXC module,which effectively distributes the sub-carriers in different channels in the power communication transmission network system into many sub-communication modules equally,so as to achieve balanced communication processing and improve the efficiency of power communication transmission network.Experiments show that this research method improves the ability of power communication network resource allocation.
