Abstract
In a method for enabling a wind energy system to stay within noise immission limits, the rotational speed of the turbine rotor is reduced as soon as set values are reached in terms of sound level, wind speed, direction of the wind or time of the day. The second part of the inventive method consists in installing wind turbines which do not have a reduced speed on the side of a first wind turbine which is sheltered from the wind so that the first turbine has a reduced speed.
Claims16
A method of operating a wind park comprising at least two wind power installations, wherein the rotary speed of at least one wind power installation is set in dependence on the wind direction and/or the wind strength and/or the time of day, in such a way that a predetermined sound level is not exceeded at a predetermined immission point.
A method of operating a wind park comprising:
- positioning a first wind power installation at a first location;
- positioning a sound sensing device at a second location;
- measuring a sound level being emitted by the first wind power installation at the second location;
- and
- controlling the speed of the first wind power installation in such a way that a predetermined sound level is not exceeded as measured at the second location.
