Problems solved by technology

Since each start-up requires a delay of 2 to 5 minutes, the start-up time of the wind turbine is prolonged.
In actual operation, the power loss caused by the prolongation of the start-up time of a wind turbine may not be much. is immeasurable

Embodiment Construction

[0034] Features and exemplary embodiments of various aspects of the 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 the present invention.

[0035] figure 1 The topological diagram of the wind farm provided by the embodiment of the present invention. figure 1 A wind farm 101 , a wind turbine 102 and a central monitoring facility 103 are shown in .

[0036] Such as figure 1 As shown, the wind farm 101 includes multiple wind power generators 102, and the central monitoring device 103 is connected to the ring network of each wind power generator 102 in the wind farm 101 through an optical communication line. The central monitoring device 103 collects the operating condition data of each wind power generating set 102 for statistical analysis, and distributes the data statistical analysis results to each wind generating set 102 to control the operation of e...

Abstract

The invention discloses a starting control method and device for a wind generating set and a storage medium. The method includes the steps that wind direction data and wind speed data of the wind generating set in a wind power field are obtained; according to the wind direction data and the wind speed data, whether or not wind rises in the wind power field is predicted; if yes, a current wind direction is sent to the wind generating set of the wind power field so that the wind generating set can perform yawing for wind facing according to the current wind direction; in response to completion of yawing for wind facing, starting operation is executed on the wind generating set in the wind power field, wherein the wind speed data is larger than preset starting wind speed. By the adoption of the technical scheme in the embodiment of the method and device, whether or not the wind rises in the wind power field can be effectively predicted, yawing for wind facing is performed on the wind generating set in advance according to the prediction result, and accordingly the starting time of the wind generating set is shortened.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and in particular to a start control method and device for a wind power generating set, and a storage medium. Background technique [0002] At this stage, if the wind power generating set is in the standby state and the wind speed measurement value lasts for a period of time, such as 2 to 5 minutes, is greater than the start-up wind speed, the wind power generating set is controlled to perform a start-up operation. Since a delay judgment of 2 to 5 minutes is required each time the machine is started, the start-up time of the wind power generating set is prolonged. In actual operation, the power loss caused by the prolongation of the start-up time of a wind turbine may not be much. is immeasurable. Contents of the invention [0003] Embodiments of the present invention provide a start-up control method and device for a wind power generating set, and a storage medium, whic...
