Within groups of wind turbines feeding power to the common utility grid a synchronization may propagate through the grid with the effect that blades of different turbines pass the respective towers simultaneously leading to a short term pulsation of the power fed into the grid. The invention remedies this effect and relates to devices and methods in which the shafts of various turbines are synchronized with a phase-shift in order that the turbines blades do not simultaneously pass the respective towers. The result is that the aggregated power from the group of turbines is stabilized. The invention permits deployment of twin bladed turbines in parks of wind turbines. |
