Inverter

Inverters for wind turbines for grid compatibility

More than 90% of the wind turbines installed worldwide have a directly grid-connected asynchronous generator, which is why no inverter is needed. In this country, however, the concept of gearless or geared wind turbines with synchronous generator, rectifier, DC link and inverter is increasingly being used. The advantage lies in the higher efficiency and the unneeded reactive current. A wind turbine of this type can be operated with variable speed and can be excellently adapted to the wind speed. This ensures optimal aerodynamic performance. First and foremost, the inverter adapts the full generator output to the required voltage and grid frequency. Since the wind turbine's generator is not bound to a specific speed, the electricity is produced at a variable frequency. It is not possible to feed them directly into the grid , which is why the inverter with its adaptive function is essential. The concept dates back to 1993, which is why many of these systems are still available on the secondary market.
