Embodiment 1
[0027] 1) The basic principle of maximum power tracking control
[0028] For a specific wind power generation system, no matter whether the wind power generation system is a direct drive system or a non-direct drive system, once the system is formed, the maximum output power point of the wind turbine under the specific environmental wind speed must be determined. At different wind speeds, there will be and figure 1Similar wind speed-power characteristics. Therefore, for the actual wind power generation system, a set of wind speed-power characteristic curves can be provided in advance for the wind power generation system under study based on empirical statistics. Correspondingly, for a specific wind power generation system, a " Wind speed-maximum power point characteristic curve" is used as the initial control characteristic curve during system control. Considering the complexity, time-consuming and test cost of the actual wind turbine characteristic test, the characteristics...
