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.

    智能電網(wǎng)在應(yīng)對(duì)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(lái)新型電網(wǎng)的基本模式[1-2],其網(wǎng)絡(luò)安全對(duì)保障國(guó)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(cè)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(wú)線通信等[5-6],但隨著電力需求的快速增長(zhǎng),這些通信方式已難以滿足保證海量數(shù)據(jù)安全、信號(hào)高速傳輸、網(wǎng)絡(luò)升級(jí)靈活的要求[7]。因此,國(guó)家電網(wǎng)開始研究寬帶微功率(Broadband Micro-power,BMP)無(wú)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(guò)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(cè)試。而良好的一致性測(cè)試系統(tǒng)能夠使測(cè)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(cè)試系統(tǒng)對(duì)驗(yàn)證協(xié)議開發(fā)的準(zhǔn)確性至關(guān)重要。
