Abstract
A method for detecting a shadow condition from a wind turbine and a system for detecting a shadow condition are provided. An atmospheric condition detected from an atmospheric condition detector is compared to a threshold. From the comparison a determination is made that the atmospheric condition is shadow producing. The shadow condition is detected using the determination.
Claims16
A method of detecting a shadow condition from a wind turbine, the method comprising:
- determining a geometry condition is present which is effective to produce a shadow at a location of concern;
- detecting an atmospheric condition of an atmosphere by an atmospheric condition detector, wherein detecting the atmospheric condition is a function of transmitting energy from the atmospheric condition detector and receiving a reflection of the energy off particles in the atmosphere;
- comparing the atmospheric condition to a threshold;
- determining the atmospheric condition is shadow producing from the comparison;
- and
- detecting the shadow condition in response to the geometry condition determined to produce the shadow at the location of concern and to the atmospheric condition determined to be shadow producing;
- wherein detecting the atmospheric condition includes detecting one or more atmospheric conditions selected from the group consisting of:
- an amount of aerosols, an aerosol formation, an amount of clouds, a cloud formation, a height of a cloud or clouds, a structure of the atmosphere, a precipitation, a gas presence, a gas concentration, a wind turbulence, a wind speed, a change in wind direction, and a wind current.

A shadow detection system comprising:
- an atmospheric condition detector separated from a wind turbine by a distance;
- and
- a controller communicatively coupled to the wind turbine by a network and configured for:
- determining a geometry condition is present which is effective to produce a shadow at a location of concern;
- detecting an atmospheric condition of an atmosphere using the atmospheric condition detector, wherein detecting the atmospheric condition is a function of transmitting energy from the atmospheric condition detector and receiving a reflection of the energy off particles in the atmosphere;
- comparing the atmospheric condition to a threshold;
- determining the atmospheric condition is shadow producing from the comparing;
- and
- detecting a shadow condition in response to the geometry condition determined to produce the shadow at the location of concern and to the atmospheric condition determined to be shadow producing;
- wherein detecting the atmospheric condition includes detecting one or more atmospheric conditions selected from the group consisting of:
- an amount of aerosols, an aerosol formation, an amount of clouds, a cloud formation, a height of a cloud or clouds, a structure of the atmosphere, a precipitation, a gas presence, a gas concentration, a wind turbulence, a wind speed, a change in wind direction, and a wind current.
