The application discloses a kind of dual wind wheel wind
turbine operation control methods, comprising: obtaining the speed and
pitch angle of the front and rear wind wheels of dual wind wheel wind
turbine under current
wind speed;With the maximum overall output power of dual wind wheel wind
turbine as the target, the target speed and
pitch angle of the front and rear wind wheels of dual wind wheel wind turbine under current
wind speed are determined;
Linearization model based on
state space of the transmission chain of the front and rear wind wheels is established respectively;Based on the
linearization model, a
state observer, a disturbance adjustment controller and a quadratic
regulator are introduced, and the
torque controller and the
pitch controller of the front and rear wind wheels are designed to control the front and rear wind wheels.The method can take the maximum
power output of the whole
machine as the target, realize a control strategy based on
linear quadratic regulation and disturbance adjustment technology, to solve the
mutual influence problem of the front and rear wind wheels of dual wind wheel wind turbine during operation, improve the robustness of the
system, improve the overall wind
energy absorption rate of dual wind wheel, and fully exert the high-efficiency
wind energy conversion capacity of dual wind wheel wind turbine.
