Description

technical field [0001] The present application generally relates to the field of wind power, and more specifically, relates to a power curve optimization device and method for a wind power generating set. Background technique [0002] In order to optimize the power generation performance of wind turbines and have strong on-site adaptability, the current development of wind turbines is platform-based. The hardware configuration of the same platform not only includes different towers and blade configurations, but sometimes Generators with flexible and adjustable power will also be configured. The ultimate goal of these differentiated designs is to pursue the lowest cost of electricity. For this purpose, it is necessary to maximize the power generation performance, including optimizing the cut-out wind speed, rated speed, rated power, Optimal pitch angle, windward deviation and other methods. However, these methods are based on the approximation or correction of the standard p...
