智能电网环境下广域网通信系统的研究
摘要
智能电网是电网的发展趋势,智能电网的实现需要先进通信系统的支持。智能电网环境下广域网是实现智能电网各个领域之间通信的网络,它承载的通信业务种类很多,包括SCADA业务、语音控制业务、广域测量业务等,各种通信业务对通信的需求(带宽、实时性、安全性)不同。本文分析了广域网的通信业务,得到在智能电网环境下的广域网的通信业务的通信需求。广域网通信系统的构建需要先进通信技术的支持,目前广域网主要的通信技术包括物理层技术、数据链路层技术、网络层技术。各层的通信技术和协议共同构建了广域网的通信系统。OTN技术结合了SDH和WDM技术的优点,自动交换光网络(ASON)技术具有实现广域网通信的优势。根据通信技术的性能分析,得出具体的通信技术在广域网通信中的应用。在广域网的主流通信技术中,MPLS技术是主要的链路层技术。文章针对MPLS技术和与其结合的其他相关技术(Diff-serv技术、MPLS-VPN技术)进行分析,根据广域网各种业务的不同需求,给出智能电网广域网通信业务传输的实现框架,使其满足通信业务的实时性和QoS等通信需求。文章通过网络仿真软件实现对广域网通信的仿真,通信网路的构建采用MPLS技术。根据仿真的结果分析MPLS技术对某些业务的通信需求的满足程度。
The Smart Grid is the development trend of the electric power. The realization of the Smart Grid needs the support of advanced communications system. The WAN in Smart Grid is to achieve the communication between domains of the Smart Grid network, the WAN carrys many kinds of communications services, including SCADA services, voice control services, the wide-area measurement services. Diversified communication services have many kinds of communication requirements (bandwidth, real-time and safety). In this article, we analyze the communication services of WAN and conclude the communication requirements of the WAN services in Smart Grid. The construction of the WAN communication system needs the support of advanced communications technologies. The current wide-area network communications technologies mainly include the physical layer, data link layer and network layer. Communication technologies and protocols of all layers are together to establish the WAN communication system. OTN technology combines the advantages of SDH and WDM, automatical switched optical network (ASON) technology has many advantages in realizing the wide-area network communication. In this paper, we conclude the specific communication technology application in WAN according to the communications technology performance analysis. MPLS is the main link layer technology among the communication technologies of the WAN. For MPLS technology and the combination of other related technologies (Diff-serv technology, MPLS VPN technology), accordding to the different requirements of the WAN various sevices, we conclude the implementation framework of the sevices transfer in the smart grid WAN to meet the real-time,the QoS and some other communication requirements. We achieve to the simulation of the WAN by network simulation software, establish the communication network with MPLS technology, and analyze the satisfaction to communication requirements of some services according to the simulation results.
