Abstract
Due to dramatic increase in power demand for future mobile networks (LTE/4G, 5G), hybrid (solar/wind/fuel) powered base station has become an effective solution to reduce fossil fuel consumption. Such base stations are powered by small wind turbines (SWT) having nominal power in the range of 1.5- 7.5 kW. In the context of the OPERA-Net2 European project, the study aims to quantify and mitigate radio interaction between such SWTs and BTSs. Compared to megawatt WTs, SWTs have the diversity of shape, material and orientation (horizontal / vertical). Thus, a simple representative model (RSWT) was first designed. It is fully metallic to correspond to the worst radio case and its dimensions are scalable to SWT nominal power. In this paper, the RSWT dimensions have been optimized to improve the match of RCS between the RSWT and realistic SWT models having the same nominal power. To verify, comparisons have been done between the RSWT and 3.5 kW Nheowind-100 model (IDSUD ENERGIES). A scaled prototype of the 3.5 kW RSWT with ratio 1:10 was manufactured. Its RCS as a function of azimuth angle was measured in an anechoic chamber at 9 and 17 GHz with different blade positions. Comparison between simulation and measurement shows a good agreement.

Such base stations are powered by small wind turbines (SWT) having nominal power in the range of 1.5- 7.5 kW. In the context of the OPERA-Net2 European project, the study aims to quantify and mitigate radio interaction between such SWTs and BTSs. Compared to megawatt WTs, SWTs have the diversity of shape, material and orientation (horizontal / vertical). Thus, a simple representative model (RSWT) was first designed. It is fully metallic to correspond to the worst radio case and its dimensions are scalable to SWT nominal power. In this paper, the RSWT dimensions have been optimized to improve the match of RCS between the RSWT and realistic SWT models having the same nominal power. To verify, comparisons have been done between the RSWT and 3.5 kW Nheowind-100 model (IDSUD ENERGIES). A scaled prototype of the 3.5 kW RSWT with ratio 1:10 was manufactured. Its RCS as a function of azimuth angle was measured in an anechoic chamber at 9 and 17 GHz with different blade positions. Comparison between simulation and measurement shows a good agreement.</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Région Bretagne</li></region><settlement><li>Brest</li><li>Lorient</li></settlement><orgName><li>Université de Bretagne Occidentale</li><li>Université de Bretagne-Sud</li><li>Université européenne de Bretagne</li></orgName></list><tree><country name="France"><region name="Région Bretagne"><name sortKey="La, Tran Vu" sort="La, Tran Vu" uniqKey="La T" first="Tran Vu" last="La">Tran Vu La</name></region><name sortKey="Comblet, Fabrice" sort="Comblet, Fabrice" uniqKey="Comblet F" first="Fabrice" last="Comblet">Fabrice Comblet</name><name sortKey="Elenga, Serge" sort="Elenga, Serge" uniqKey="Elenga S" first="Serge" last="Elenga">Serge Elenga</name><name sortKey="Le Pennec, Francois" sort="Le Pennec, Francois" uniqKey="Le Pennec F" first="François" last="Le Pennec">François Le Pennec</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
