Definitions

  • the invention provides a method and a system for power regulation of a generator driven by a rotor of a wind turbine.
  • Wind turbines are designed for a nominal load and nominal power production.
  • the rotational speed of the wind turbine has been controlled by rotating the blades into or out of the wind, i.e. by blade pitching.
  • the rotational speed is maintained at a fixed speed, often called nominal speed, and in other turbines, the rotational speed is variable and a frequency converter is used to match the frequency of the connected grid.
  • known wind turbines are generally controlled based on one or more loads acting on the wind turbine, e.g. expressed by a wind speed, a blade bending moment, or expressed by similar measurable condition.
  • Various methods have been used to cut-off the wind turbine from the grid or to completely stop rotor rotation at a predefined wind speed, e.g. at 25 m/s.
  • a wind turbine is defined with a power curve which gives the power output of the wind turbine as a function of wind speed.
  • the wind turbine starts to generate power at a cut in wind speed.
  • the turbine then operates under part load (also known as partial load) conditions until the rated wind speed is reached.
  • part load also known as partial load
  • the rated power of a wind turbine is defined in IEC 61400 as the maximum continuous electrical power output which a wind turbine is designed to achieve under normal operating and external conditions.
  • Large commercial wind turbines are generally designed for a lifetime of 20 years and their rated power output takes into account that lifespan. However, it is sometimes necessary to reduce the power output of a wind turbine.
  • reducing the power output means, in the context of this invention, that the wind turbine outputs less than the usual amount of power than would be expected at a certain wind speed.
  • the output power is regulated down from the power curve of the wind turbine.
  • the power output is regulated down from the rated power of the turbine.
  • An operator may want to reduce the power output of a wind turbine so that it can operate as a "spinning reserve", i.e. the turbine produces a smaller amount of power than would be expected for a given wind speed, but when needed, it can deliver more power to a grid in a short time frame by running at its regular power output as defined by the turbine's power curve.
  • a utility power grid is configured so that it responds to instantaneous load variation on the grid. Wind turbines are well suited to act as peak load power supplies for compensating for short-term variations in the grid load because their power output can be regulated very quickly.
  • the power output of the turbine is determined by the rotational speed of the rotor and the driving moment of the rotor:
  • M is the driving moment on the rotor, torque [Nm], and
  • ⁇ is the rotational speed of the rotor [rad/s]
  • a method of reducing the power output of a wind turbine the wind turbine having a rotor and a generator for producing power, the rotor operating at a first rotational speed, the method comprising the steps of:
  • the power request signal indicating by how much the power output of the wind turbine should be reduced; determining a second rotational speed of the rotor based on the power request signal, the second rotational speed being lower than the first rotational speed;
  • the turbine Since the output power of the turbine is determined based on an external request, the turbine may remain in operation with a reduced power output.
  • the adaptation of the power output to the external request allows a more continuous power production which can be changed swiftly, and compared with a turbine which is completely stopped, the amendment of the power output facilitates a much quicker control of the turbine.
  • the wind turbine can continue in production in periods with a low power demand without introducing an increased wear on the transmission due to torque reversals which may occur when the turbine is operating with a reduced power output.
  • the advantage of being able to power-derate the turbine is that the owner of the turbine can keep the turbine running as a spinning reserve, which can be brought to full power production in a short period of time, which may be within seconds. Further, the turbine may contain elements which are maintained in better shape when always being active. This is the case e.g. with regards to bearings which may suffer from being held in a fixed position of the rotor- bearing-ring relative to the stator-bearing-ring.

  • Power request defined herein may specify a signal which is generated externally and received by the wind turbine.

  • the rotor may be operated at a first driving moment and the method may further comprise the steps of:
  • the speed reduction can be delayed such that the power is reduced first, and the speed is reduced second.
  • the power is reduced sequentially, followed by a speed reduction and then again a power reduction.
  • the reduction in power and speed is carried out simultaneously but with different durations. Generally, the power can be changed instantly while the change in rotational speed typically takes longer due to the inertia of the heavy drive train and rotor system.
  • the steps of reducing the rotational speed to the second rotational speed and operating at the second driving moment may be carried out simultaneously.
  • the second rotational speed of the rotor may be determined from a lookup table.
