Embodiment 1
[0023] figure 1 It is a flow chart of a braking control method for a wind power generating set according to an embodiment of the present invention. The braking control method can be used to perform braking and load reduction control on the wind power generating set when the power grid fails, so as to reduce the shutdown load of the wind power generating set, so that the wind turbine can stop safely, thereby solving the problem of power grid failure in the prior art. The problem of affecting the mechanical life of the wind turbine caused by emergency shutdown in the event of a failure.
[0024] In this embodiment, the main control system of the wind power generating set is used as an example to illustrate the braking control method, but those skilled in the art should understand that in practical applications, any other equipment with corresponding data collection and processing functions , can refer to this embodiment to implement the braking control method of the wind power ...
Embodiment 2
[0038] figure 2 It is a flow chart of the braking control method of the wind power generating set according to the second embodiment of the present invention.
[0039] The braking control method in this embodiment can be regarded as an optional specific implementation manner of the braking control method in the first embodiment above. The executive body of the brake control method of this embodiment can be the main control system of the wind power generating set, but those skilled in the art should understand that in practical applications, any other equipment with corresponding data collection and processing functions can refer to This embodiment implements the braking control method of the wind power generating set of the present invention. For example, the execution subject of the brake control method in this embodiment may also be an external controller independent of the main control system and the converter of the wind power generating set, or a control device integrat...
Embodiment 3
[0070] image 3 It is a flow chart of the braking control method of the wind power generating set according to the third embodiment of the present invention.
[0071] The braking control method of the wind power generating set in this embodiment includes control methods on the converter side and the main control system side.
[0072] The control method on the converter side of this embodiment includes:
[0073] S310. Detect whether the power grid fails.
[0074] In a feasible implementation manner, the converter periodically detects the state parameters of the power grid, and determines whether a fault occurs in the power grid by judging whether the state parameters of the power grid exceed a preset safety threshold. Among them, the grid fault includes one or more of high grid voltage, low grid voltage, high grid frequency, low grid frequency, unbalanced grid voltage, unbalanced three-phase current, overcurrent protection, current overload, low overtime, high overtime Multi...
