Embodiment Construction
[0019] The embodiment of the present invention provides a doubly-fed wind power generation control system parameter optimization design method. In the design of PI parameters, by introducing a discrete domain converter, the parameters of the continuous system are transformed into discrete domains, and the PI parameters are designed, thereby It is relatively close to the sampling calculation of the actual system, so that the PI parameter design of the current inner loop can be more accurate, and the control effect of fast and accurate tracking of the current of the dual PWM converter can be improved, thereby optimizing and improving the control performance of the doubly-fed wind power generation system .
[0020] In order to better describe the embodiment of the present invention, the specific embodiment of the present invention will be described in conjunction with the accompanying drawings, such as figure 1 Shown is a schematic flowchart of a method for parameter optimization...
