The Windbooster project (en) Presentation Transcript

  • 1. THE WINDBOOSTER PROJECT
  • 2. The wind turbine The function of a wind turbine is to steal energy to the intercepted air flow and convert it into electricity. WIND TURBINE HORIZONTAL AXIS WIND TURBINE UPWIND DOWNWIND VERTICAL AXIS WIND TURBINE DARREIUS SAVONIUS GORLOW DARREIUS - SAVONIUS 28/09/2013 The Windbooster project

  • 4. The Windbooster technology (2/2) Windbooster is a vertical axis wind turbine fed by a conveyed stream designed to solve the drawbacks that limit the efficiency of traditional wind turbines with vertical axis. Windbooster is a wind turbine specially designed for on-roof installation. The rotating part of the machine (the so- called rotor ) is completely contained within a static conveyor . This characteristic makes the product particularly suitable for installations in urban environments: in case of structural failure (remote event but possible) the conveyor carries out the function of a screen and avoids the ejection of solid fragments potentially dangerous. The conveyor also carries out the important task of improve the quality of the air flow which feeds the inner rotor: the Windbooster is able to use more efficiently the turbulent flows available in case of installations in urban environments with an overall size clearly lower than the competitors with the same rated power. 28/09/2013 The Windbooster project
  • 5. Windbooster 1.0: power curve The wind turbine power curve describes, from power point of view, the real behavior of a wind turbine with the change in wind speed (net of all aerodynamic, mechanical and electrical losses). It is shown the mechanical and electrical power curve, power expressed in W (left y-axis). In addition are shown efficiencies of devices that are integral part of the wind turbine electrical system (right y- axis). The instantaneous speed of the wind is shown in x-axis. 28/09/2013 The Windbooster project
  • 6. Status of the project ü Intellectual property protection: it is in the final stage the procedure for the submission of the patent application. ü Competitor analysis: it is on going a market analysis of vertical axis wind turbines with a rated power in the range 300 W ÷ 3 kW. To date they are been considered 19 wind turbines. ü Characterization of the wind turbine: a Windbooster 1.0 (rated power of 1 kW) was installed in a test site. To date the "track record" has a time extension equal to 1 year. 28/09/2013 The Windbooster project
  • 7. Comparison with competitors The Windbooster 1.0 is compared with the selected wind turbines (competitor analysis) considering the following efficiency parameters. Parameter name Specific parameter Integral parameter Power coefficient yes no Annual Energy Production no yes Specific Annual Energy Production yes yes Annual Energy Production / cost no yes An efficiency parameter is defined as specific if it takes into account the size of the wind turbine: it allows to compare machines with different sizes, making the production of energy concerning to the size of the wind turbine. An efficiency parameter is defined as integral if it takes account of all possible operating conditions that the wind turbine can experience: it looks at the overall performance of the wind turbine in a certain time interval. To make more meaningful the comparison with competitors, when it is made using a specific parameter the comparison is extended to all selected wind turbines (rated power in the range 0.3 to 3 kW), while when the parameter is not specific , the comparison is limited to wind turbines with a rated power similar to that of Windbooster 1.0 ( 1.5 kW). 28/09/2013 The Windbooster project
  • 8. Windbooster 1.0: power coefficient The power coefficient measures how much the wind turbine is efficient in subtract energy to the feeding air flow: efficiency not only in terms of power subtracted but also in terms of space required. It is shown a comparison between power coefficient average values: the average is performed on power coefficient values developed in the range of wind speed values from 3 to 15 m/s. The Windbooster 1.0 gets the better of all competitor turbines! 28/09/2013 The Windbooster project
  • 9. Windbooster 1.0: Annual Energy Production It is shown the Annual Energy Production (AEP), expressed in kWh, versus expected annual average wind speed values. The Windbooster 1.0 (red curve) is particularly suitable for use in environmental contexts characterized by medium/low wind speed values (less than 7.5 m / s). 28/09/2013 The Windbooster project
  • 10. Windbooster 1.0: specific AEP (1/2) It is shown the specific Annual Energy Production, expressed in kWh/m2, versus expected annual average wind speed values. The Windboobster 1.0 (red curve) appears to be a turbine with an high specific AEP: it overcomes all turbines with the same rated power and it competes against the bigger wind turbines thanks to its smaller overall dimensions. 28/09/2013 The Windbooster project
  • 11. Windbooster 1.0: specific AEP (2/2) It is shown the specific Annual Energy Production, expressed in kWh/m2, versus expected annual average wind speed values. The Windboobster 1.0 (red curve) appears to be a turbine with an high specific AEP: it overcomes all turbines with the same rated power and it competes against the bigger wind turbines thanks to its smaller overall dimensions. 28/09/2013 The Windbooster project
  • 12. Windbooster 1.0: specific AEP % (1/2) It is shown the specific Annual Energy Production, expressed in percentage of Windbooster 1.0 specific Annual Energy Production, versus expected annual average wind speed values. The red line (Windbooster 1.0) separates turbines with higher specific AEP (ordinate> 100%) from those with a lower specific AEP (ordinate <100%). 28/09/2013 The Windbooster project
  • 13. Windbooster 1.0: specific AEP % (2/2) It is shown the specific Annual Energy Production, expressed in percentage of Windbooster 1.0 specific Annual Energy Production, versus expected annual average wind speed values. The red line (Windbooster 1.0) separates turbines with higher specific AEP (ordinate> 100%) from those with a lower specific AEP (ordinate <100%). 28/09/2013 The Windbooster project
  • 14. Windbooster 1.0: AEP/cost % It is shown the AEP/cost ratio, expressed in percentage of Windbooster 1.0 AEP/cost ratio, versus expected annual average wind speed values. The Windbooster 1.0 gets the better of all competitor turbines with the same rated power. 28/09/2013 The Windbooster project
  • 15. The Windbooster series: use the experience gained with the model Windbooster 1.0 to develop a new range of products. Windbooster project developments ü Identify power classes more "attractive" for the market. ü Develop a technical solution for a multi-turbine plant ("totem"). ü Develop a technical solution for a hybrid plant (solar + wind). ü Identify an efficient and economical technical solution to equip the Windbooster series with a storage system. ü Improve the product aesthetics to make it more suitable for urban installation. 28/09/2013 The Windbooster project
