Embodiment 1
[0031] This embodiment provides a method for monitoring the environment of the nacelle of a wind turbine, which is used for monitoring the environment of the nacelle of a large-scale wind turbine. This method aims at the problem that the heat dissipation cannot be effectively improved when the ambient temperature of the nacelle of a large-scale wind turbine is monitored. Realize the analysis of functional requirements, select and research the precise control algorithm of stepper motor suitable for the control system. The differential sliding mode algorithm is used to precisely control the stepping motor, which realizes the air supply action inside the cabin and the automatic replacement feeding of the filter screen of the filter system. Through the comparative analysis of the temperature curves of the gearbox inside the engine room of the two groups of prototypes, it is concluded that the engine room environment control system has significantly reduced the heat dissipation of t...
