Abstract

The invention provides a control method for axial flow fans of a wind generating set. The control method comprises the steps: acquiring the temperature of an engine room in the wind generating set and the power of the wind generating set; and controlling the starting of each of the axial flow fans in sequence according to the temperature and the power, and controlling the stopping of each of the axial flow fans in a sequence opposite to a starting sequence. The phenomenon that the axial flow fans are in a starting state all the time in the process that the wind generating set works can be avoided by controlling the starting and stopping of the axial flow fans according to the temperature of the engine room in the wind generating set and the power of the wind generating set, so that the energy consumption of the axial flow fans can be reduced; the stepped control on the axial flow fans is realized by controlling the starting of the plurality of axial flow fans in sequence, so that the energy consumption of the axial flow fans can be further reduced; in addition, the phenomenon that the axial flow fans are disordered in a stopping process can be avoided by controlling the stopping of each of the axial flow fans in the sequence opposite to that starting sequence, so that the stability of the axial flow fans in the stopping process can be improved.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a method for controlling an axial flow fan of a wind power generator. Background technique [0002] As an important mechanical part of the wind turbine, the axial fan is mainly used to reduce the ambient temperature of the cabin in the wind turbine. In order to ensure that the ambient temperature of the nacelle is not higher than the operating temperature of each component in the nacelle, it is generally required that the axial flow fan is in working condition during the working period of the wind power generating set. Because the axial flow fan itself needs to consume a certain amount of electric energy during work, but in fact, the nacelle does not necessarily need to start the axial flow fan to reduce its ambient temperature during the operation of the wind turbine, so there is energy waste in the current axial flow fan operation. Bigger problem. Contents of the inventi...
