电力通信几种主要传输方式的应用分析

Discussion and analysis about transmission mode of electric power communication

通过对目前电力通信专网中3种主要传输方式分析认为,它们均各具优劣势,只有通过优势互补,才能构建一个更加完善、合理的电力通信网络。文章提出:SDH光纤通信将继续是构建电力通信网的主导技术;微波通信可以作为干线光纤传输的备份;电力线载波以其成本低廉更适合用作县调、地调等信息量较小的传输选择,还可成为可靠的备用通信方式。

It＇s no doubt that SDH over optical fiber communication plays an important role in electric power communication network. But whether the network based on optical fiber is the most reliable and the cheapest, what about the future of PLC and digital microwave, through analyzing and comparing the three techniques of PLC, digital microware and SDH over optical fiber, their advantages and disadvantages were found respectively. Only through their interdependence and interaction, a more perfect and reasonable electric power communication network will be constructed. The paper proposes that SDH optical fiber communication will be dominant technique of constructing electric power communication network. Microwave communication can be a backup of main optic fiber transmission, which will be an effective supplement while optical fiber is not suitable and a handy technical means for emergency scheme. PLC still is a choice because of its low cost, it is suitable for lesser information situation such as county or area＇s transmission, and also can be a reliable backup communication mode.
