【摘要】：隨著智能電網(wǎng)和信息化建設的大力推進,分組數(shù)據(jù)在眾多業(yè)務中的比例占據(jù)主導地位,電力業(yè)務不僅對通信網(wǎng)絡的穩(wěn)定性、可靠性、準確性要求越來越高,同時也對通信網(wǎng)絡靈活、高效的業(yè)務接入能力和多樣化的服務質(zhì)量提出了新的要求。現(xiàn)網(wǎng)中傳統(tǒng)的SDH/MSTP網(wǎng)絡對于生產(chǎn)控制類業(yè)務具有良好的承載能力,但無法滿足大量IP業(yè)務傳輸需求。業(yè)務的發(fā)展為PTN技術提供了發(fā)展空間,目前它已經(jīng)成為支撐電力通信網(wǎng)主流技術之一。PTN設備均內(nèi)置了自動保護倒換算法和性能/告警監(jiān)視功能,它們能保證在網(wǎng)絡故障的條件下具備自愈能力。當發(fā)生故障時,PTN網(wǎng)絡中的自動保護倒換可以確保數(shù)據(jù)的完整性和維持服務質(zhì)量。本文圍繞PTN網(wǎng)絡保護倒換機制對電力通信業(yè)務性能的影響進行研究。第一,對適用于PTN網(wǎng)絡的各類保護倒換方式的工作機理和關鍵技術進行了詳細分析,并總結出了PTN網(wǎng)絡的保護通用功能。通過不同保護方式的對比,給出了各類電力通信業(yè)務適用的保護方式。第二,對電力通信業(yè)務的性能需求進行分析,在此基礎上研究了PTN保護倒換對其產(chǎn)生的影響。第三,搭建了實驗室環(huán)境下的PTN傳輸平臺,在不同保護倒換方式下對業(yè)務性能的影響進行了測試,得出了PTN倒換狀態(tài)下對業(yè)務的時延及可靠性會產(chǎn)生一定影響,但均在業(yè)務承受范圍之內(nèi)的結論。第四,依托河北省電力公司PTN網(wǎng)絡,從其承載的不同業(yè)務類型入手,對PTN倒換狀態(tài)下的業(yè)務性能影響進行了測試,測試結果表明PTN保護倒換會對TDM及以太網(wǎng)業(yè)務性能產(chǎn)生影響,但是滿足業(yè)務性能需求。本課題研究的內(nèi)容,為PTN保護倒換技術在電力通信業(yè)務上更好的應用提供了一定的理論依據(jù)和數(shù)據(jù)參考,為PTN廠家更好改進網(wǎng)絡生存機制提供了技術支撐。
[Abstract]:With the development of smart grid and information construction, the proportion of packet data plays a dominant role in many services. The power business not only requires the stability, reliability and accuracy of the communication network, but also the accuracy of the network. At the same time, new requirements for flexible, efficient service access and diversified quality of service (QoS) of communication networks are put forward. The traditional SDH/MSTP network in the present network has good load-carrying capacity for the production control services, but it can not meet the needs of a large number of IP services. The development of service has provided the development space for PTN technology. At present, it has become one of the mainstream technologies supporting power communication network. PTNs have built-in automatic protection switching algorithm and performance / alarm monitoring function. They can guarantee the ability of self-healing under the condition of network failure. The automatic protection switching in PTN network can ensure the integrity of data and maintain the quality of service. This paper focuses on the influence of PTN network protection switching mechanism on the performance of power communication services. Firstly, the working mechanism and key technologies of various protection switching methods suitable for PTN network are analyzed in detail, and the general protection functions of PTN network are summarized. Through the comparison of different protection modes, the suitable protection methods for various kinds of electric power communication services are given. Secondly, the performance requirement of power communication service is analyzed, and the influence of PTN protection switching on it is studied. Thirdly, the PTN transmission platform under the laboratory environment is built, and the influence on the service performance under different protection switching mode is tested. It is concluded that the delay and reliability of the service will be affected by the PTN switching state. However, all within the scope of the business within the conclusion. Fourthly, based on the PTN network of Hebei Electric Power Company, the influence of PTN switching on service performance is tested from different service types. The test results show that PTN protection switching will have an impact on TDM and Ethernet service performance. But meet the business performance requirements. The content of this paper provides a certain theoretical basis and data reference for the better application of PTN protection switching technology in the electric power communication business, and provides technical support for the PTN manufacturers to improve the network survival mechanism better.
