ABOUT THE PROJECT

Now, the project is looking for an investor. The required total investment is €2,200,000 for two years, including at least €100,000 until December of 2019.


      The idea of the new wind power plant emerged as a result of researches of the air flow vortex concentrator invented by myself (International application for invention PCT/IB2017/054185 from July 12, 2017 priority date June 20, 2017, under patent RU 2655422 C1 registered and published on May 28, 2018). The formula of the invention contains only two essential features and provides broad legal protection. The technical result is achieved due to the curvature of the surfaces and the relative position of the wind directing elements.
      The coefficient of wind energy use determined during these studies, at certain ratios of the height of the vortex concentrator to the diameter of its working zone, achieved up to 50%. At the same time the wind directing elements of the tested models of the vortex concentrator and turbine blades did not have an aerodynamic profile, and the geometry of the turbine blades was not quite ideal.
      In the result of the completed researches have the first sketches (see the Fig. 1, press the button below) and technical solutions of the industrial version of the new megawatt class wind power plant based on a vortex concentrator emerged. The main parts of the unit are as follows:

    1. Air flow vortex concentrator covered by a domed roof and equipped with lightning conductors, consists of identical wind directing elements (in the given version there are six of them) made of metal structures covered by sheets of glass-reinforced plastic and having an aerodynamic profile;
    2. Supporting structures, including the concrete or pile foundation and supports made of prestressed concrete, serve as the basis for the vortex concentrator and steel beams, which fix the shaft of the turbine rotor in the bearing units from longitudinal and lateral shifts;
    3. The turbine consisting of rods with blades at the ends and a hub with a control system (disk in the center), which is responsible for turning the rods to change the pitch angle, and for moving the rods -in and -out the hub (International application for invention PCT/IB2019/057055 from August 21, 2019 priority date July 21, 2019);
    4. Generator room (the dome-shaped building in the base) including the building itself, the generator with the multiplicator, electric equipment and controller with the operator's control panel.

      For a private use, instance for power supply of a country house, farm or electric vehicle charging stations, the wind power plant could be significantly simplified. The vortex air flow concentrator could act as a supporting structure. In the wind power plants of up to 15-20 meters height, the air flow vortex concentrator can be turned over so that the working zone and the turbine are on the top, and its wind directing elements serve as supports for the turbine.

      The vortex concentrator for itself could find its application also in other areas, for example, in a buildings ventilation system.

DISADVANTAGES OF MODERN SYSTEMS

The main problems of modern wind turbines (those with horizontal axis types) that inhibit the development of wind power engineering and which are solved by a new type of wind power plant:


Inefficiency of modern wind power plants in gusty wind and / or with a rapid change in wind direction.


Narrow operating range of wind speeds, high start-up speed and rated wind speed.


Complexity of maintenance (repair and replacement of worn parts of the wind power plant) due to the location of the main power components, yaw system, control systems etc. on a mast.

Design constraints of the installed capacity due to the location of the majority mass of the equipment (generator, multiplicator, yaw system, electrical equipment and turbine) on a mast.

Low profitability in the absence of government benefits and subsidies due to low Efficiency rated output (Capacity factor) and short lifetime (15-25 years) that also creates the problem of recycling.

Large exclusion zone around wind farms not only because of the noise but also because of scattering of the turbine fragments in case of destruction or of ice while icing over considerable distances.

ADVANTAGES OF THE NEW TECHNOLOGY


      High efficiency of the proposed wind power plant is provided by the airflow vortex concentrator (which does not require any yaw system) as well as by the turbine blades’ control system that is located in a hub in the center of the working zone (the disk in the base of the vortex concentrator) from where rods with blades at their ends move out radially. The vortex concentrator provides a spiral movement of the captured airflow to the turbine blades through the outer edge of the working zone. The width of the airflow is mere 20-25% of the working zone’s radius that is there is no any air movement in the center of the vortex concentrator like in the center of a hurricane.


      The concentration of the airflow and the moment of force applied to the blades of the turbine provide a low start-up speed of the unit (up to 1 m/s).

      The control system provides the turning of the blades to change pitch angle as well as the retracting of the rods for transformation the low-speed multi blade turbine in three-bladed turbine with high rotation speed or completely retracts all the rods to prevent breakage in a storm wind. All this extends the operating range of wind speed, and also reduces the wind load when wind speed increases up to 15-20 m/s or higher.

      Due to the mass of the hub with the control system it is a flywheel with auto balancing system, smoothing the gusty wind and preventing low-frequency vibrations. This system ensures the smooth operation of the generator and reduces the wear of mechanical systems. The expected Efficiency rated output (Capacity factor) is 60-80% vs. 30-40% in the modern wind turbines, depending on wind power potential of the region.

      Generator, multiplicator, electrical equipment and controller with operator’s control panel are at the bottom of the wind power plant, in a domed building, providing the easy access to the systems of the power plant and the absence of restrictions on the mass/capacity of the equipment.

      The bearing structures of prestressed concrete provide the lifetime of the new wind power plant from 50 to 100 years and more.

      The turbine’s location in the working zone of the vortex concentrator, surrounded on all sides by bearing elements of the structure, eliminates uncontrolled scattering of fragments of the blades in case of destruction, and of ice while icing. In addition, the external elements that surround the working zone shield from the noise produced by the turbine.


      This design allows to scale the wind power plant. The Bearing structures can be initially built with the expectation of a larger height and power, with a larger diameter of the working zone. At the same time, a concentrator with a working zone made as an insert and a generator are initially installed designed for the less power, thereby reducing the initial investment of the wind farm. The design of the turbine with retractable rods with blades allows to adapt it to different diameters of the working zone. To increase the power of the wind power plant, it is enough to change only the concentrator with the working zone to larger ones and buy an additional generator, which is installed together with the first one.

      The implementation of this project will allow wind power to grow from a subsidized industry into a profitable component of the world's electricity production. It will be possible to use previously not promising regions in terms of wind energy.

SUMMARY OF THE PROJECT


    MARKET
     Almost 2 years ago, EU plans for wind power investments were announced. The EU's planned investment in wind energy will reach €239 billion (cumulative) by 2030.
     And in May of 2019, the elections to the European Parliament showed the attitude of the electorate to the programs for clean energy and carbon free industry in Europe. «In the next 5 years EU funding must be targeted at projects that deliver on our commitments under the Paris Climate Agreement: that’s more funding for research and innovation in zero-carbon energy, starting with wind; and for electricity grids which we need to expand as we deliver the energy transition.»
     It is innovative technical solutions in the field of clean energy that will primarily get access to these EU funds. Consequently, wind turbine manufacturers will hunt for any developments in this area, since, if there is a new technology, the replacement of wind turbines that have expired or construction of new ones, using the old technology will become inexpedient. The company, the first to establish mass production by these technologies, will receive an absolute advantage in the market.

    GOALS
    1. To make a technological breakthrough in wind power by offering a new, more profitable and safer, more reliable wind power plant, which can be operated in regions that are called “poor” and “marginal” in modern wind power, as well as in regions with severe climatic conditions and to develop technological processes to establish serial production of new wind power plants.
    2. To seek and develop new areas of this technology, for example, in building ventilation systems, as well as to develop areas related to wind power, for example, systems of accumulation of excess wind energy through the production and accumulation of various energy carriers (hydrogen, methane, etc.)
