Definitions

  • the invention relates to a method to regulate the output power production of a wind turbine with respect to the market price of the electricity and with respect to the life time of components of the wind turbine.
  • TLC Total Cost Control
  • the TLC is prepared to monitor the major wind turbine components in view to their lapsed lifetime. Based on this result the wind turbine may be "down regulated” in view to its output power to extend the lifetime of the components if needed.
  • stress and loads, which are acting on the components of the wind turbine are reduced in their effects.
  • the whole wind turbine withstands the ambient influ- ences longer and thus its lifetime is prolonged.
  • the document US 6 850 821 B2 discloses a deliberatelyCONTROL SYSTEM FOR A WIND POWER PLANT".
  • the system includes a damage module and a contral module.
  • the damage module compares existing stress conditions on one or more component parts of the wind power plant to current energy generating costs.
  • the contral module alters electric power generated by the wind power plant based upon the comparison.
  • the output power production of a wind turbine is regulated.
  • a wind speed is estimated for the wind turbine based on local meteorological data, which are allocated to the wind turbine site.
  • a load which acts on at least one component of the wind turbine, is estimated based on the estimated wind speed.
  • a lifetime consumption of the component is estimated based on the estimated load.
  • the output power of the wind turbine is estimated based on the estimated wind speed.
  • a reference value is calculated, which takes into account the market price of the estimated output power and the estimated lifetime consumption.
  • Settings of the wind turbine are adjusted to increase or to decrease the out ⁇ put power production of the wind turbine based on the refer ⁇ ence value. Summarized: the calculated reference value influences the lifetime consumption of the wind turbine component (s) via the increased or decreased output power. This is done in regard to a beneficial gain in view to the market price of the out ⁇ put power.
  • the method invented provides a new evaluated balance between the lifetime of the wind turbine and the amount of money, be ⁇ ing generated by the market price of the output power of the wind turbine.
  • the owner of the wind turbine receives an optimum oper ⁇ ating time of the wind turbine (even in the "down regulated output power mode") with respect to an optimized benefit from the produced and sold electricity.
  • the method invented predicts load rates of wind turbine com ⁇ ponents in a way that the "Turbine Load Control, TLC" is not in conflict with the efforts of a "smart grid”.
  • the method invented shows a novel way to implement and use the TLC while no further changes needs to be done at the wind turbine .
  • FIG. 1 A first figure.

  • the second block is called “Load Forecast” and is used to es ⁇ timate a load, which acts on at least one component of the wind turbine. This estimation is based on the estimated wind speed .
  • the third block is called "Bidding" and is used to calculate a reference value, which takes into account the market price of the estimated output power and the estimated lifetime con- sumption.
  • the fourth block is called “Control” and is used to adjust the settings of the wind turbine, specified by the fifth block named “Wind Turbine”.
  • the settings are adjusted to in ⁇ crease or to decrease the output power production of the wind turbine based on the reference value.
  • the method invented is explained now by help of a physical model, which refers to the FIG 1.
  • a metrological estimator is used to estimate one or several wind parameters (e.g. the mean wind speed, turbulences, wind variances, the wind direction, the air density, the tempera ⁇ ture, etc.
  • the knowledge of other wind turbines is additionally used to estimate local weather phenomena (i.e. wake, inflow angle and wind share) .
  • a physical model of the wind turbine is now set in view to an estimated wind field, which approaches the wind turbine.
  • the loads, acting on all major components, are estimated for all control strategies of the wind turbine.
  • the model is updated time by time - especially for the point of time where the wind turbine settings are set for a start-operation of the wind turbine.
  • the forecast preferably uses these parameters:
  • the load-forecast h() is preferably based on a "Metrological Parkmodel", which uses metrological data directly to estimate load rates of dedicated components of the wind turbine.
  • the load rate is a function of the output- power, the mean wind and of the turbulence. This function is known by the manufacture of the wind turbine.
  • the load-forecast is preferably based on a "Metrological- Turbine Model", using knowledge of the local area of the wind turbine. This model allows a more precise prediction of load rates. Examples of local condition can be hills, trees, tur ⁇ bines in the neighborhood of the dedicated wind turbine, etc . These functions show the dependencies for this model:
  • Windshare g (wind direction)
  • Load Rate f (power, mean wind, turbulence, windshare, con ⁇ trol option)
  • the control option can be different ways of controlling the wind turbine. It could be curtailed, or have some grid ser ⁇ vices enabled
  • the function g can be estimated using so called "siting tools".
  • the function f is known by the wind turbine manufac- turer.
  • the load-forecast is preferably based on a "Metrological- Turbine Data" model.
  • the method gathers all data driven meth ⁇ ods - i.e. all methods where the function h() is estimated using historical data.
  • Load Rate h (power, Mean wind speed, turbulence, air den ⁇ sity, wind direction, control option)
  • h() It is even possible to use a neural network to estimate the function h() .
  • the training of h() may use the model from one of the examples above as starting point.
  • the estimated lifetime consumption depends on the power pro ⁇ duction in a non-linear way.

Abstract

La présente invention concerne un procédé de régulation de la production électrique d'une turbine éolienne en fonction du prix de l'électricité sur le marché et de la durée de vie des composants de cette turbine. La production électrique d'une turbine éolienne est régulée selon le procédé de l'invention. La vitesse du vent est estimée pour cette turbine sur la base des données météorologique locales applicables au site de la turbine. Une charge agissant sur au moins l'une des composantes de la turbine éolienne est estimée sur la base de cette estimation de la vitesse du vent, puis la consommation sur la durée de vie du composant est calculée sur la base de cette charge estimée. La puissance de sortie de la turbine éolienne est estimée sur la base de cette estimation de la vitesse du vent. Une valeur de référence est calculée, qui prend en compte le prix sur le marché de la puissance de sortie estimée et la consommation sur la durée de vie estimée. Les paramètres de la turbine sont ajustés pour augmenter ou réduire la production électrique de la turbine éolienne sur la base de cette valeur de référence.
