The Next Generation of Wind Turbines: Hydro-Electronic Transmission

Wednesday June 20th, 8:00-9:00am San Francisco / 11:00am-12:00pm New York / 5:00-6:00pm Paris and Frankfurt

Calventis SA has developed a new power drive system for wind turbines that aims to significantly improve the wind turbines performance for the production of electricity. This state-of-the-art hydro-electronic power drive eliminates the need for the widely used mechanical gearbox which:

  • enables the use of a gearless hydraulic motor and reduces the current industry benchmark of a 40% failure rate of gearboxes.
  • reduces operating and maintenance costs by 20%
  • increases the overall performance of the turbines by approximately 30%
  • makes the system suitable for both on-grid and stand-alone energy production as well as for vertical and horizontal axis systems

 Calventis’ hydro-electronic drive enables manufacturers to build a wind turbine with variable rotation speed and a synchronous generator with a selectable constant rotation speed. This concept allows the connection of the generator directly to the grid without a power inverter. This will turn a conventional wind turbine into a true power plant, stabilizing voltage, frequency and the overall grid and allow direct grid connection for decentralized energy production.

One major challenge for Wind Farm operators is the international requirement for quality electricity supply. A significant advantage of Calventis’ control- and hydro-electronic technology combined with the synchronized generator is the constant quality monitoring and maintenance of electricity supplied to the grid which benefits the estimated 50% of the world market that has problems with the quality of the energy supply.
