摘要: 為應(yīng)對智能電網(wǎng)發(fā)展要求,國家電網(wǎng)正在研究寬帶微功率技術(shù),旨在提高電網(wǎng)通信的傳輸速率和實(shí)時(shí)性。為保證協(xié)議開發(fā)的準(zhǔn)確性,需要進(jìn)行一致性測試,確保后期各產(chǎn)商生產(chǎn)的寬帶微功率設(shè)備能夠互聯(lián)互通。因此,設(shè)計(jì)了一種針對寬帶微功率MAC層的一致性測試系統(tǒng),并詳細(xì)講解了系統(tǒng)的軟硬件設(shè)計(jì)。最后對系統(tǒng)的功能和性能進(jìn)行驗(yàn)證,驗(yàn)證結(jié)果表明,該一致性測試系統(tǒng)已滿足各項(xiàng)要求,可實(shí)現(xiàn)對寬帶微功率MAC層的一致性測試。

Abstract: The State Grid of China is researching broadband micro-power technology to response the development requirements of smart grid and improve the transmission rate and real-time performance of grid communication. In order to ensure the accuracy of the protocol development, a conformance testing should be conduct to ensure that the broadband micro-power equipment produced by various manufactures can be interconnected. Therefore, a conformance testing system for the MAC layer of the broadband micro-power was designed in this thesis and the hardware and software design of the test system were explained in detail. Finally, the system was verified from function and performance. The verification results show that the conformance testing system has met all the requirements and can realize the conformance testing of the MAC layer of the broadband micro-power.
Key words : broadband micro-power;conformance test;MAC layer;test system

    智能電網(wǎng)在應(yīng)對全球氣候變化,促進(jìn)世界經(jīng)濟(jì)可持續(xù)發(fā)展等方面具有重要的作用,是未來新型電網(wǎng)的基本模式[1-2],其網(wǎng)絡(luò)安全對保障國家重要設(shè)施安全具有關(guān)鍵作用[3]

    用戶用電信息采集系統(tǒng)是智能電網(wǎng)完成用電數(shù)據(jù)采集、電網(wǎng)狀態(tài)監(jiān)測等功能的實(shí)現(xiàn)載體[4],該系統(tǒng)的本地通信方式主要有RS485通信、電力線載波通信、微功率無線通信等[5-6],但隨著電力需求的快速增長,這些通信方式已難以滿足保證海量數(shù)據(jù)安全、信號高速傳輸、網(wǎng)絡(luò)升級靈活的要求[7]。因此,國家電網(wǎng)開始研究寬帶微功率(Broadband Micro-power,BMP)無線通信技術(shù),該技術(shù)具有高帶寬、高速率、高穩(wěn)定性等優(yōu)點(diǎn),可實(shí)現(xiàn)數(shù)據(jù)的高速和高實(shí)時(shí)性傳輸。

    為避免協(xié)議開發(fā)過程中的二義性理解[8],保證各協(xié)議實(shí)現(xiàn)之間能夠互聯(lián)互通,需要進(jìn)行一致性測試。而良好的一致性測試系統(tǒng)能夠使測試工作更高效,所以設(shè)計(jì)實(shí)現(xiàn)一種適用于寬帶微功率MAC層的一致性測試系統(tǒng)對驗(yàn)證協(xié)議開發(fā)的準(zhǔn)確性至關(guān)重要。
