Problems solved by technology

[0004] However, the inventors of the present application have found that when the wind speed is high, the speed of the wind generator set rises faster, and the start-up and grid-connected control methods in the prior art will make the speed of the wind generator set slow before pitch adjustment. It exceeds

Example Embodiment

[0050] Features and exemplary embodiments of various aspects of embodiments of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the invention.

[0051] As a renewable new energy source, wind energy has been widely developed. With the gradual expansion of the scale of wind power generators, how to improve the utilization rate of wind energy of wind power generators has become an urgent problem to be solved.

[0052] The grid-connected process of the wind turbine is that when the speed of the wind turbine reaches and stabilizes at the grid-connected speed, the main controller of the wind turbine controls the converter to load the generator with electromagnetic torque, so that the wind turbine Output Power.

[0053] According to the principle of energy conservation, the energy conservation formula after the wind turbine is connected

Abstract

The embodiment of the invention discloses a start-up and grid-connected control method and device for a wind power generator set as well as a storage medium. The start-up and grid-connected control method comprises the following steps: according to the rotating speed of the wind power generator set during a blade opening process, acquiring the rotating acceleration speed of the wind power generator set; judging whether the rotating acceleration speed of the wind power generator set is greater than the preset rotating acceleration speed or not; if the rotating acceleration speed of the wind power generator set is greater than the preset rotating acceleration speed, starting up a feedback adjustor used for adjusting the rotating speed of the wind power generator set, setting the grid-connected rotating speed required for the wind power generator set as the target value of the feedback adjustor, and setting the rotating speed of the wind power generator set as the input value of the feedback adjustor; and according to the output value of the feedback adjustor, adjusting the blade opening speed till the rotating speed of the wind power generator set reaches the grid-connected rotatingspeed. By adoption of the start-up and grid-connected control method and device disclosed by the embodiment of the invention, the blade adjusting operation can be performed before the rotating speed of the wind power generator set reaches the grid-connected rotating speed.
