Abstract
The present invention concerns a wind power installation having a control apparatus for operational management of the wind power installation and a method of controlling a wind power installation having a control apparatus for operational management. In order to take the largest possible amount of energy from the wind the control apparatus takes into consideration the height of the location of erection of the wind power installation and/or the height of the wind power installation. The method according to the invention also detects air density, transmits signals which are derived from the air density and which represent the air density to the control apparatus, and the air density is taken into consideration by the control apparatus in operational management.
Claims25
A method of controlling a wind power installation positioned at an installation location during normal operation, wherein the wind power installation includes a plurality of components including at least one rotor blade and an electrical generator, the method comprising:
- determining air density data at the installation location;
- determining an exciter power based on the air density data;
- and
- supplying the exciter power to the electrical generator.
A wind power installation comprising:
- at least one rotor blade;
- an electrical generator, coupled to the at least one rotor blade;
- and
- a control device, coupled to the electrical generator, to control the electrical generator by supplying an exciter power, wherein the control device determines an exciter power provided to the electrical generator using air density data determined at an installation location, wherein the installation location is the location where the wind power installation is positioned during normal operation.
