Problems solved by technology
[0003] However, the external environment in which the wind turbine is in operation will change, and the above-mentioned operating speed range of the wind turbine that has been determined in the design stage does not fit well with the actual wind resources at the installation site of the wind turbine. This will reduce the power generation performance of wind turbines, which needs to be improved urgently

The invention provides a method and device for adjusting the rotating speed of a wind generating set in a self-adaptive manner. The method includes the steps that wind sources of an installation machine site of the wind generating set are determined; the starting and stopping frequency of the wind generating set, the turbulence intensity value of the installation machine site and the loads of thewind generating set are determined according to the determined wind sources; the minimum running rotating speed of the wind generating set is adjusted based on the blade passing frequency of the windgenerating set, the first-order inherent frequency of a tower of the wind generating set, the starting and stopping frequency and the output power of the wind generating set; and the maximum running rotating speed of the wind generating set is adjusted based on the rated rotating speed limit value of the wind generating set, the turbulence intensity value and the loads. By the adoption of the method and device for adjusting the rotating speed of the wind generating set in the self-adaptive manner, the power generation performance of the wind generating set can be optimized, the running safetyof the wind generating set is ensured, and the economical efficiency of the wind generating set is improved.
Description
technical field [0001] The present invention generally relates to the technical field of wind power, and more specifically, relates to a method and a device for adaptively adjusting the rotational speed of a wind power generating set. Background technique [0002] At present, wind turbines generally determine an operating speed range in the design stage, that is, wind turbines operate between a minimum operating speed (also called grid-connected speed) and a maximum operating speed (also called rated speed). [0003] However, the external environment in which the wind turbines operate will change, and the above-mentioned operating speed range of the wind turbines determined at the design stage does not match the actual wind resources at the installation site of the wind turbines. This will reduce the power generation performance of the wind turbine, which needs to be improved urgently. Contents of the invention [0004] The purpose of the present invention is to provide a...
