Embodiment Construction

[0016] Referring to FIG. 1 , a wind farm 10 comprising a plurality of wind turbines 12 is schematically shown. For ease of illustration, only a few rows of wind turbines arranged at equal intervals are shown in the wind farm, but it is understood that there can be more or fewer wind turbines in the wind farm, and these wind turbines can also be adjusted according to the terrain, prevailing wind direction and Similar factors are laid out in various graphs or arrays.

[0017] As shown in FIG. 2, each wind turbine 12 has a respective controller 14 for receiving signals related to wind direction, wind speed, load and the like, and controlling the corresponding wind turbine according to these signals. More specifically, tower controllers are typically provided to receive and process sensor information on the respective wind turbine towers. Each tower is connected to the tower controller in order to input the values ​​measured locally by the measuring sensors into the tower control...

Abstract

A method and system for controlling a windpark power plant includes a central processing and control unit (16) operatively coupled to wind turbines (12) in the windpark (10) to receive data from and selectively transmit at least one of data and control signals to each wind turbine, to reduce fatigue loads and comply with power limits.

Description

technical field [0001] The invention relates to the operation and control of a large number of wind turbines arranged in a wind park. Background technique [0002] It is well known that the greatest part of the high stresses to which a wind turbine is exposed at high wind speeds shortens the lifetime of the wind turbine. A known method to reduce the stress on the rotor, nacelle, tower and tower foundation is to reduce the rotational speed of the wind turbine rotor and reduce the output power of the wind turbine at high wind speeds. [0003] Wind turbines are usually equipped with measurement and control systems to provide independent feedback on changing wind conditions. These systems are designed to maximize wind energy capture while minimizing the effects of fatigue and overloading. The effectiveness of these control systems is limited by sensor technology. With this in mind, measurement systems and probes located on a particular wind turbine need to operate in feedback...
