Obviously, the drawings in the following description are some embodiments of the present invention.

[0043] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0044] In the related art, with the increase in the power of wind turbine sets, the heat generation of heat-generating components such as gearboxes, motors or converters becomes increasingly large. Some manufacturers use an air-water cooling system for heat dissipation, connect several heat dissipation plates in a row, place them in the external environment on the top of the nacelle, and rely on natural wind blowing through the heat dissipation plates with coolant inside to achieve convective heat transfer.

[0045] When the wind turbine is running, the yaw system can make the nacelle always face the wind, so that the heat sink always faces the main wind direction. However, the air flow passing through the heat sink first passes through the rotating blades, so the wind flow is disturbed and blocked by the blades before reaching the heat sink. The existing technology makes all heat sinks face the same direction and parallel to the windward side of the nacelle, so that not all heat sinks have the optimal heat dissipation efficiency.

[0046] As mentioned above, the air inflow angle of the air flow passing through the heat sink changes dynamically, and the air inflow angle of the air flow passing through each heat sink is also different at different wind speeds and different wind wheel speeds.

Optionally, a database can be pre-set, and the database stores data of multiple yaw error angles, and data of the optimal air inflow angle of each heat sink corresponding to each yaw error angle of the wind turbine. The yaw error angle of the wind turbine acquired in real time in the previous step is matched in the database to determine the optimal air inflow angle data of each heat sink corresponding thereto.

Among them, the preset rule can be set as needed.

[0067] Optionally, a preset rule can be set to calculate the average value of the multiple air inflow angles of a heat dissipation plate corresponding to the simulated yaw error angle, and use the average value as the optimal air inflow angle of the heat dissipation plate under the simulated yaw error angle, so as to obtain the optimal air inflow angle of each heat dissipation plate corresponding to the simulated yaw error angle, and then obtain the optimal air inflow angle of each heat dissipation plate under different simulated yaw error angles.

[0068] Optionally, a preset rule can be set to arrange the multiple air inflow angles of a heat dissipation plate corresponding to the simulated yaw error angle in ascending or descending order, and use the median of the arranged multiple air inflow angles as the optimal air inflow angle of the heat dissipation plate, so as to obtain the optimal air inflow angle of each heat dissipation plate corresponding to the simulated yaw error angle, and then obtain the optimal air inflow angle of each heat dissipation plate under different simulated yaw error angles.

[0069] S23. Generate a database according to the optimal air inflow angle of each heat dissipation plate corresponding to the simulated yaw error angle.

[0070] S24. Match the optimal air inflow angle of each heat dissipation plate corresponding to the simulated yaw error angle in the database according to the yaw error angle.

[0071] In the embodiment of the present invention, by simulating according to different working condition parameters, the air inflow angle set of each heat dissipation plate is obtained, realizing the acquisition of air inflow angle data based on simulation, and saving the cost of actual application testing of the wind turbine. Determine the optimal air inflow angle of each heat dissipation plate in the air inflow angle set corresponding to the simulated yaw error angle according to a preset rule, realizing the screening of multiple air inflow angles in the air inflow angle set to obtain the optimal inflow angle that meets the rules. Furthermore, generate a database according to the optimal air inflow angle of each heat dissipation plate corresponding to the simulated yaw error angle, and match the optimal air inflow angle of each heat dissipation plate corresponding to the simulated yaw error angle in the database according to the yaw error angle, realizing the simple and rapid generation of a database supported by simulation, providing a reliable data basis, and the optimal air inflow angle of each heat dissipation plate matched according to the database has higher reliability.

[0073] S31. Obtain the historical parameter information of the wind turbine.

[0074] Wherein, the historical parameter information includes the set of air inlet angles of each heat dissipation plate corresponding to the historical yaw error angles of the wind turbine under different time parameters.

[0075] Specifically, the historical parameter information of the wind turbine can be obtained, and the air inlet angles of each heat dissipation plate under the historical yaw error angles can be determined according to the historical parameter information. The multiple air inlet angles corresponding to each heat dissipation plate at the same historical yaw error angle and different times are used as a set.

[0076] S32. Determine the optimal air inlet angle of each heat dissipation plate in the set of air inlet angles of each heat dissipation plate corresponding to the historical yaw error angle according to a preset rule.

[0077] Specifically, for the historical yaw error angle, each heat dissipation plate has multiple air inlet angles, and these multiple air inlet angles need to be further screened according to a preset rule to determine the optimal air inlet angle. Among them, the preset rule can be set as needed.

[0078] Optionally, a preset rule can be set to calculate the average value of the multiple air inlet angles of a heat dissipation plate corresponding to the historical yaw error angle, and the average value is used as the optimal air inlet angle of the heat dissipation plate under the historical yaw error angle, so as to obtain the optimal air inlet angles of each heat dissipation plate corresponding to the historical yaw error angle, and further obtain the optimal air inlet angles of each heat dissipation plate under different historical yaw error angles.

[0079] Optionally, a preset rule can be set to arrange the multiple air inlet angles of a heat dissipation plate corresponding to the historical yaw error angle in ascending or descending order, and the median of the arranged multiple air inlet angles is used as the optimal air inlet angle of the heat dissipation plate, so as to obtain the optimal air inlet angles of each heat dissipation plate corresponding to the historical yaw error angle, and further obtain the optimal air inlet angles of each heat dissipation plate under different historical yaw error angles.

[0081] S34. Match the optimal air inlet angles of each heat dissipation plate corresponding to the historical yaw error angle in the database according to the yaw error angle.

[0082] In an embodiment of the present invention, historical parameter information of a wind turbine is obtained, and a set of air inflow angles of each heat dissipation plate at a historical yaw error angle is determined according to the historical parameter information. Since the set of air inflow angles is determined from the historical parameter information, it has great reference value and guiding significance. The optimal air inflow angle of each heat dissipation plate is determined from the set of air inflow angles of each heat dissipation plate corresponding to the historical yaw error angle according to a preset rule, so as to screen multiple air inflow angles in the set of air inflow angles and obtain an optimal inflow angle that meets the rule. Furthermore, a database is generated according to the optimal air inflow angle of each heat dissipation plate corresponding to the historical yaw error angle, so as to simply and quickly generate a database with historical data support, which has high reference value and guiding significance, provides a reliable data basis, and the optimal air inflow angle of each heat dissipation plate matched according to the database has higher reliability.

[0083] According to the wind turbine heat dissipation method based on yaw error provided by the present invention, after the yaw error angle of the wind turbine is obtained in real time, the following steps are further included:

[0084] S14. When the yaw error angle is greater than a preset threshold, set the angle of each heat dissipation plate to a preset angle.

[0085] Specifically, the yaw error angle obtained in real time can be compared with the preset threshold. When the yaw error angle is greater than the preset threshold, it can be determined that the wind turbine has yawed severely at this time, and the angle of each heat dissipation plate can be set to the preset angle. Among them, the preset threshold and the preset angle can be set according to actual needs.

[0086] In an embodiment of the present invention, when the yaw error angle is greater than the preset threshold, the wind turbine has yawed severely. At this time, setting the angle of each heat dissipation plate to the preset angle saves the calculation cost of matching according to the yaw error angle in the database and directly sets the angle of each heat dissipation plate to the preset angle.
