DESCRIÇÃO DETALHADA DA INVENÇÃODETAILED DESCRIPTION OF THE INVENTION
A presente invenção tem como intuito aproveitar aenergia cinética eólica do deslocamento de ar gerado pelodeslocamento de trens subterrâneos (metrôs) em seus túneis delinha férrea, cujas velocidades de deslocamento de ar (ventos) sãoatraentes para geração de energia elétrica.The present invention aims to take advantage of the kinetic wind energy of the displacement of air generated by the displacement of underground trains (subways) in their railway tunnels, whose air displacement speeds (winds) are attractive for electric power generation.
Devido ao deslocamento dos trens, e do sistema detúneis, que causa um efeito de tunelamento do deslocamento de ar,promovendo velocidades de ventos em média de 2,5 a 20 m/s,espaçados de forma regular e bastante precisa, devido aprogramação logística do tráfego dos trens do sistema. Um dospromovedores do bom funcionamento do sistema proposto nestainvenção, é exatamente a regularidade dos trens, promovendo umagarantia de que os rotores eólicos verticais e/ou horizontais,dispostos nos túneis do sistema, nas estações e/ou nos própriostrens, serão movimentados pelos deslocamentos de ar proporcionadospelo movimento dos trens, e assim mover os geradores de energiaelétrica sejam eles síncronos ou assíncronos.Due to the displacement of the trains and the tunnel system, which causes a tunneling effect of air displacement, it promotes wind speeds averaging 2.5 to 20 m / s, spaced evenly and fairly precisely, due to the logistic scheduling of the air. system train traffic. One of the promoters of the proper functioning of the system proposed in this invention is the regularity of the trains, promoting a guarantee that the vertical and / or horizontal wind rotors, arranged in the system tunnels, stations and / or the trains themselves, will be moved by air displacements. provided by the movement of the trains, and thus move the power generators whether synchronous or asynchronous.
A equação 1 apresenta a potência eólicadisponibilizada, por um dado vento que atinge um rotor eólico auma velocidade vl, e deixa o rotor eólico a uma velocidade v3,onde A é a seção transversal do rotor e ρ é a massa especifica do ar.Equation 1 presents the wind power provided by a given wind that hits a wind rotor at a speed vl, and leaves the wind rotor at a speed v3, where A is the rotor cross section and ρ is the specific mass of air.
Equação 1:Equation 1:
<formula>formula see original document page 4</formula><formula> formula see original document page 4 </formula>
O sistema proposto nesta invenção é formadobasicamente por um rotor eólico 1 que pode ser vertical, quando oseu eixo de rotação é ortogonal ao plano horizontal e horizontal,quando o seu eixo de rotação é ortogonal ao plano vertical, umaentrada de ar 2 de alimentação do rotor 1, onde a velocidade do aré v1 conforme a equação 1.The system proposed in this invention is basically formed by a wind rotor 1 which can be vertical when its axis of rotation is orthogonal to the horizontal and horizontal plane, when its axis of rotation is orthogonal to the vertical plane, a rotor feed air inlet 2 1, where the air velocity is v1 according to equation 1.
Um gerador de eletricidade 3, que pode sersincrono ou assincrono, um jusante 4 ou saida do ar posicionado nasaida do rotor 1, onde a velocidade do ar é a v3 conforme aequação 1. Ainda um eixo de rotação e mancai 5 do rotor 1 e umsistema de ampliação ou redução de velocidade 6, uma ou maisconforme a necessidade, posicionado junto ao rotor 1.An electricity generator 3, which may be synchronous or asynchronous, a downstream 4 or air outlet positioned at the rotor 1 outlet, where the air velocity is v3 according to equation 1. Further a rotor and bearing axis 5 of rotor 1 and a system extension or reduction speed 6, one or more as needed, positioned next to rotor 1.
O sistema proposto nesta invenção poderá serencontrado em muitas configurações conforme as possibilidadestécnicas de cada sistema de vias de tráfego ferroviáriosubterrâneo e/ou de superfície.The system proposed in this invention may be found in many configurations according to the technical possibilities of each underground and / or surface rail traffic system.
Na figura 2, apresentamos um exemplo deconfiguração para ser aplicada em uma estação de trenssubterrâneos, particularmente na saída e/ou entrada dos túneisentre as plataformas de embarque e desembarque. Nestaconfiguração, ainda existe a possibilidade de o sistema serinstalado na estrutura de separação do sistema de proteção dousuário onde devido ao tunelamento do ar, existe uma melhora nodesempenho do sistema.In Figure 2, we present an example of the configuration to be applied at an underground train station, particularly at the exit and / or entrance of the tunnels between the departure and disembarkation platforms. In this configuration, there is still the possibility of the system being installed in the separation structure of the user protection system where due to air tunneling, there is an improvement in the system performance.
No entanto, o sistema de geração de eletricidadepor energia eólica poderá ser montado em qualquer outro localinternamente aos túneis dos trens subterrâneos e/ou desuperfícies, não deixando de destacar que ainda existem asconfigurações onde o sistema geração de eletricidade por energiaeólica é montado de forma estratégica em uma localização dentro dotúnel em que a velocidade do trajeto do trem é máxima, e como estáem um túnel a velocidade de deslocamento do ar também acompanhaesta condição e também se apresenta como máxima, favorecendo aquantidade de energia eólica disponibilizada para ser convertida aenergia elétrica. A figura 1, apresenta esquematicamente algunsprováveis posicionamentos ao longo de um túnel.However, the wind power generation system can be mounted anywhere other than underground train tunnels and / or surfaces, but it should be noted that there are still settings where the wind power generation system is strategically mounted on a location within the tunnel where the train travel speed is maximum, and since they are in a tunnel the air travel speed also follows this condition and is also maximum, favoring the amount of wind energy available to be converted to electric energy. Figure 1 schematically shows some likely positions along a tunnel.
A figura 2 é um exemplo de uma configuração dosistema proposto de geração de energia elétrica pela energiaeólica do deslocamento de ar nos túneis do metrô, montado em umaestação.Figure 2 is an example of a proposed system configuration of electric power generation by wind energy from air displacement in subway tunnels, mounted in a station.
Uma das configurações que podem ser adotadas é ado sistema de geração elétrica através de rotores eólicos 1, nopróprio trem, como indica a figura 3. Considerando-se uma seçãotransversal do túnel de vias férreas subterrâneas (Metrô) e/ou desuperfície, incluindo uma seção transversal de um trem desta via,temos vários possíveis posicionamentos para a admissão de ar dosistema de geração de energia elétrica pela energia eólica,conforme indica algumas a figura 3. Também podem ser adotadasdiversas formas de seção transversal de admissão de ar para estesistema.One of the configurations that can be adopted is the electric generation system using wind rotors 1, on the train itself, as shown in figure 3. Considering a cross section of the underground (underground) and / or surface railway tunnel, including a section In a cross section of a train on this track, we have several possible positions for the air intake of the wind power generation system, as shown in some of Figure 3. Several forms of air inlet cross section can also be adopted for this system.
Os sistemas eólicos hoje em dia, possuem diversasconfigurações de rotores 1, dos mais diversos desenhos.Wind systems nowadays have several rotor configurations 1, of the most diverse designs.
Principalmente, são divididos em duas principais categorias: os deeixo vertical, e os de eixo horizontal.Mainly, they are divided into two main categories: the vertical axis, and the horizontal axis.
Para o sistema de geração de energia elétricaatravés da energia eólica do deslocamento de ar proporcionado pelomovimento dos trens nos túneis de vias férreas subterrâneas e/oude superfície, podem ser utilizados rotores eólicos 1 verticais ouhorizontais, dependendo do local onde serão instalados no sistema.For the power generation system through the wind displacement wind energy provided by the movement of trains in underground and / or surface railway tunnels, vertical or horizontal wind turbines may be used, depending on where they will be installed in the system.
A Figura 4 mostra um esquema de cada categoria.Figure 4 shows a scheme of each category.
A energia elétrica gerada no sistema é umaenergia recuperada, uma vez que sua origem é a energia cinéticaeólica do deslocamento de ar provocado pelo movimento dos trensnos túneis. Isto significa para o sistema de transporteferroviário subterrâneo (Metrô) e/ou o de superfície, um aumentoda eficiência energética do sistema.The electrical energy generated in the system is a recovered energy, since its origin is the kinetic energy of the air displacement caused by the movement of the trains in the tunnels. This means for the underground (underground) and / or surface rail transport system an increase in the energy efficiency of the system.
Tal energia poderá ser reutilizada para aoperação das estações, e todos os seus sistemas envolvidos,inclusive os sistemas de proteção aos usuários, conforme indica aFigura 5. Também poderia ser comercializada, promovendo energiasmais limpas "Grid" nacional de energia elétrica.Such energy could be reused for the operation of the stations, and all of their systems involved, including user protection systems, as shown in Figure 5. It could also be commercialized, promoting cleaner national grid energy.
Apenas como exemplo, se considerarmos um sistemacomo este proposto nesta invenção, independente da configuração elocalização, considerando velocidades médias de deslocamento do are a quantidade de 20 a 40 rotores 1, distribuídos em todo osistema, poderíamos ter, considerando as perdas de conversão deenergia eólica em energia elétrica, potências instaladas da ordemde 2 MW a 65 MW, que poderia produzir energia para aproximadamente10.000 a 320.000 casas populares.Just as an example, if we consider a system as proposed in this invention, regardless of the configuration and location, considering average displacement velocities of the amount of 20 to 40 rotors 1, distributed throughout the system, we could have, considering the conversion losses of wind energy to electricity, installed capacities of the order of 2 MW to 65 MW, which could produce power for approximately 10,000 to 320,000 popular households.
Obviamente será percebido que enquanto o acimafoi descrito por forma de exemplo ilustrativo desta invenção,todas outras modificações e variações feitas à esta invenção, naforma que seria aparente aos especialistas na técnica, sãoconsideradas dentro do amplo escopo e âmbito desta invençãoconforme as reivindicações a seguir.Obviously, it will be appreciated that while the above has been described by way of illustration of this invention, all other modifications and variations made to this invention, as would be apparent to those skilled in the art, are considered within the broad scope and scope of this invention as set forth in the following claims.
