Embodiment 1

[0039] like Figure 1-3 As shown, the present invention is an air-to-air cooling automatic control early warning system for wind turbines, comprising:

[0040] The air inlet and outlet closing device, the air inlet filtering device 5 and the control early warning system 10; the air inlet and outlet closing device and the air inlet filtering device 5 are respectively connected with the control early warning system 10.

[0041] An air inlet 1 is arranged at the bottom of the engine room of the fan, and an air outlet 8 is arranged at the rear of the engine room of the fan; the air inlet 1 and the air outlet 8 are communicated;

[0042] The air inlet and outlet closing device includes an air inlet closing device 3 and an air outlet closing device 9; the air inlet closing device 3 is installed inside the air inlet 1, and the air outlet closing device 9 is installed inside the air outlet 8; the air inlet closing device 3 includes an air inlet The baffle 31 and the air inlet hydraul...

Embodiment 2

[0055] The invention also provides a control method for the air-to-air cooling automatic control early warning system of the wind turbine, comprising:

[0056] GPS Clock Synchronization; Synchronize SCADA system clock with GPS clock time through GPS clock synchronization device.

[0057] The PM10 dust sensor 2 collects the weather information at the air inlet 1, that is, the dust situation, and transmits the weather information collected by the PM10 dust sensor 2 to the SCADA system 11, and the SCADA system 11 transmits the weather information to the main control system; the main control system 10 Obtain the status information of the fan, and make a control strategy according to the status and weather information of the fan. When the dust concentration is greater than 150μg / m 3 When the fan control strategy is to shut down to avoid sand and dust; when the dust concentration is less than 150μg / m 3 When the fan control strategy is normal operation; the main control system inpu...

Abstract

The invention belongs to the technical field of wind power generation equipment, and particularly discloses an air-air cooling automatic control early warning system of a wind driven generator and a control method thereof, and the air-air cooling automatic control early warning system comprises an air inlet and outlet closing device, an air inlet filtering device and a control early warning system; the air inlet and outlet closing device and the air inlet filtering device are respectively connected with the control early warning system; the system also comprises an SCADA system, and the SCADA system is connected with the control early warning system. Early warning information of sand and dust weather is obtained through the PM10 dust raising sensor and transmitted to the SCADA system, the SCADA system transmits weather information to the control early warning system, the control early warning system obtains state information of the draught fan, a control strategy is made according to the state of the draught fan and the weather information, and a control scheme is made according to the control strategy sent by the control early warning system. The fan can automatically close the air inlet and outlet baffle or open the air inlet filtering device according to weather conditions, so that electrical components in the cabin and the internal environment of the cabin are protected, the service life of equipment in the cabin is prolonged, and the reliability of the equipment in the cabin is improved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation equipment, and in particular relates to an air-to-air cooling automatic control early warning system of a wind power generator and a control method thereof. Background technique [0002] The installation environment of wind turbines is complex and diverse, including plains, plateaus, and seas, and gradually develops to high-temperature desert areas. Fans inevitably face harsh natural environments, dust and floes in different seasons, and even in the edge of the desert. There may be a sandstorm attack. There are a large number of electrical components in the cabin, which requires high environmental cleanliness, providing a good working environment for the electrical components in the cabin, and minimizing the impact of the external environment on them. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings of the prior art, the purpose of the present invention is t...
