Multi bandwidth voltage controllers for a wind power plant

Abstract: The present invention relates to a wind power plant, with at least one wind turbine generator, where each of the at least one wind turbine generator has a first voltage controller with a first bandwidth, arranged for controlling a voltage level, and where the wind power plant has a power plant controller with a second voltage controller with a second bandwidth also arranged for controlling the voltage level, the first bandwidth is larger than the second bandwidth. The invention also relates to a method for controlling the voltage level of a wind power plant, by using multi bandwidth voltage controllers.

Improvements relating to the determination of rotor imbalances in a wind turbine

Abstract: A method and system for improving the balance of a rotor in a wind turbine, including; determining blade load data associated with a selected rotor blade pair; determining, based on the blade load data, pitch imbalance data associated with the selected rotor blade pair, wherein the pitch imbalance data associated with a rotor blade pair is based on measurements of at least blade loading, rotor speed and wind speed; and, determining and applying pitch control inputs to one or both of the selected rotor blade pair in order to reduce the severity of the rotor imbalance.

Estimation of remaining battery life in a wind energy application

Abstract: Method, system, and computer program product for estimating a consumed battery life of a battery used in a wind energy application. An energy storage system for use with a wind farm includes a rechargeable battery configured to be selectively charged by wind turbines or the power grid and configured to be selectively discharged to a power grid. One or more remaining battery life algorithms are used to compute a consumed battery life for the battery. A battery life curve characteristic of the battery and a state of charge profile are used as inputs to each remaining battery life algorithm.

Determination of wind turbine configuration

Abstract: Determination of Wind Turbine Configuration The present invention relates to a method and computer system for determining a configuration of a wind turbine of a given wind turbine type, the method comprising the steps of: storing in a database a plurality of combinations of physical and control parameters of the wind turbine that can be varied; determining a plurality of wind flow characteristics at a target location; applying a function which defines a relationship between a performance parameter, a fatigue life estimation, the combination of physical and control parameters and the plurality of wind flow characteristics, to at least some of the plurality of combinations in the database to determine values of the performance parameter and the fatigue life estimation for those combinations; and selecting one of the combinations of physical and control parameters as the configuration of the wind turbine for the target location on the basis of the performance parameter and fatigue life estimation values.

A system and method for monitoring and control of wl-nd farms

Abstract: The invention related to a wind farm monitoring and control system, said system comprising - at least one wind farm, - at least one intelligent management server connectable to said at least one wind farm via a data communication network, - at least one wind farm configuration tool related to said intelligent management server for establishment of connection(s) to said at least one wind farm. The present invention presents a system for monitoring and control of wind farms. The monitoring and control is performed so that it is possible to monitor and control several wind farms homogeneously. Hereby it is possible to monitor and control different wind farms simultaneously with a uniform output and it is moreover possible to compare data from the wind farms.
