The invention provides a power curve acquisition device for a wind turbine generator system. The power curve acquisition device comprises a first averaging module, a second averaging module and a power curve generation module, wherein the first averaging module is used for respectively averaging wing-speed values measured by an anemoscope and output power values measured by a power measuring device at certain time intervals T; the second averaging module is used for averaging the average wind speed value and the average output power value in each 1m / s time step at the time step intervals, so as to obtain a secondary average wind speed value and a corresponding secondary average output power value in the time step; the power curve generation module is used for creating a wing speed value-wind turbine generator output power value coordinate system, wherein data points of a plurality of secondary average wind speed values and corresponding secondary average output power values are marked in the coordinate system, and are connected into a line in sequence to obtain a power curve of the wind turbine generator system. Through the adoption of the power curve acquisition device, a power curve graph of the wind turbine generator system can be obtained according to real-time wind speeds and actual output power.
Description
technical field [0001] The invention relates to the technical field of wind power, in particular to a device for acquiring power curves of wind power generating sets. Background technique [0002] Wind energy is a clean and renewable energy source. As the main form of wind energy utilization, wind power generation is one of the renewable energy power generation methods with the most mature technology, the most large-scale development conditions and the most commercial development prospects. Since the power curve of the wind turbine is the best scale to measure the economic and technical level of the wind turbine, the analysis and research of the power curve of the wind turbine is very important, and it is closely related to the economic benefits of the wind farm. [0003] In the overall parameter design stage of the wind turbine, the power curve can be used to test the performance of the wind rotor and predict the overall performance of the unit, and the selection of the ge...
