DYNAMIC CONTROL OF ACTIVE AND REACTIVE POWER CAPABILITY FOR WIND FARMS

摘要

A control method 300 for dynamically controlling active and reactive power capability of a wind farm includes obtaining 302 one or more real-time operating parameters of each of the wind turbines. The method 300 also includes obtaining 304 one or more system limits of each of the wind turbines. Further, the method 300 includes measuring 306 at least one real-time wind condition at each of the wind turbines. Moreover, the method 300 includes continuously calculating 308 an overall maximum active power capability and an overall maximum reactive power capability for each of the wind turbines as a function of the real-time operating parameters, the system limits, and/or the real-time wind condition. Further, the method 300 includes generating 310 a generator capability curve for each of the wind turbines using the overall maximum active and reactive power capabilities and communicating the generator capability curves to a farm-level controller of the wind farm that can use the curves to maximize the instantaneous power output of the wind farm.
