The key<br \/>\nelement of the present energy storage systems for aerial tramways was then created at the centre of excellence for digital energy and electric power.<\/p>\n<p>Duvanel was supported here by a team of colleagues from Luzern University of Applied Sciences and Arts as well as UVEK (Swiss federal department of environment, transport, energy and communications).<\/p>\n<p>As a promising system, the federal department supported the cable car project through the 2050 energy strategy in public transport. The aim of this programme is to promote public transport. ABB Schweiz, FREY AG STANS, and DOPPELMAYR\/GARAVENTA were involved as industry partners.<\/p>\n<h3>How it works:<\/h3>\n<p>\u201cA funicular railway comprises two carriages, which are connected by a traction cable. When a carriage departs from the bottom station, it needs drive power, in order to gain height. Once it has covered a good half of the route, no further energy is required, as the downwards track and associated traction cable are heavy enough to pull the carriage up.<\/p>\n<p>The carriage travelling downwards now actually requires braking. The cable car is therefore constantly alternating between energy input and output,\u201d Duvanel explains the principle. \u201cThe new system now ensures that the energy released here is recovered locally,\u201d he elaborates.<\/p>\n<p>For introduction of the new energy system, two requirements need to be met: first, a PV installation on the station roof or the desire to construct one; second, space for two control cabinets. In addition to the PV installation, the battery \u2013 with storage capacity of 68 kWh \u2013 forms the central component of the energy system.<\/p>\n<p>It stores both the recovered braking energy until it can be used for the next ascent and surplus solar power from the PV installation. In the future, it is intended that some of the stored energy will be kept in reserve, so that the carriages can be returned to the stations in the event of a power failure.<\/p>\n<p>The diesel generator previously used for this purpose will therefore become redundant.<\/p>\n<\/div><style type=\"text\/css\">.fusion-builder-row .fusion-layout-column.gradient-column-6 .fusion-column-wrapper:before {content: \"\";

There is a very specific reason why the 1,700-metre route of the<br \/>\ninstallation constructed in 1887 was the perfect trial venue. \u201cWe still needed a suitable test site for our basic concept and the Biel- Magglingen funicular railway was ideal.<\/p>\n<p>It was interested in the concept and the adaptation work was very easy, as the railway was undergoing a fundamental overhaul,\u201d Duvanel justifies the choice of<br \/>\ntest site. Thanks to the modification work, the energy is now distributed across four participants: the public grid, the PV installation on the roof, the main<br \/>\ndrive and the auxiliary systems.<\/p>\n<p>The new storage system specifically ensures optimal use of the last three. They will be supported by the public grid only if the load becomes too great. This<br \/>\nconcept seems to work even in continuous operation (previously around 10 months).<\/p>\n<p>During the test phase, the power costs fell by around 30 percent. This is appreciated not only by the team of researchers from Luzern University of Applied Sciences and Arts but also by the cable car operators, as power accounts for around half of the cable car operating costs.<\/p>\n<\/div><style type=\"text\/css\">.fusion-builder-row .fusion-layout-column.gradient-column-10 .fusion-column-wrapper:before {content: \"\";

That is already a figure at which it is worth considering how the concept can be offered conveniently,\u201d Duvanel explains the next steps.<\/p>\n<p>Indeed, all these cable car types could theoretically be modified, but the expert knows that this step is also not cost effective for all of them. \u201cI would say it is actually worth thinking about this step only if the installation has to be refurbished anyway, otherwise the cost would certainly be too high.<\/p>\n<p>The location of the station is also critical. As the PV installation is a central aspect of our system, it also needs to be usable optimally, in order to achieve the values measured in Biel-Magglingen. Buildings on north-facing slopes with only limited sunlight are therefore not suitable,\u201d he elaborates.<\/p>\n<p>The amortisation period for investments in the pilot installation is expected to be fifteen years. For future, commercial installations, an amortisation period of ten years is conceivable.<\/p>\n<\/div><style type=\"text\/css\">.fusion-builder-row .fusion-layout-column.gradient-column-14 .fusion-column-wrapper:before {content: \"\"; position: absolute; width: 100%; height: 100%; top: 0; left: 0;z-index:-1;background: -webkit-gradient(linear, left top, right top, from(), to())!important;background: -webkit-linear-gradient(0deg, , )!important;background: -moz-linear-gradient(0deg, , )!important;background: -ms-linear-gradient(0deg, , )!important;background: -o-linear-gradient(0deg, , )!important;}<\/style><div class=\"fusion-clearfix\"><\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Luzern University of Applied Sciences and Arts has developed a new system for aerial tramways, which offers significant savings on energy costs. <\/p>\n","protected":false},"author":2,"featured_media":20867,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[178,247],"tags":[],"_links":{"self":[{"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/posts\/20861"}],"collection":[{"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/comments?post=20861"}],"version-history":[{"count":3,"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/posts\/20861\/revisions"}],"predecessor-version":[{"id":21434,"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/posts\/20861\/revisions\/21434"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/media\/20867"}],"wp:attachment":[{"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/media?parent=20861"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/categories?post=20861"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.simagazin.com\/en\/wp-json\/wp\/v2\/tags?post=20861"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
