Problems solved by technology

[0002] In a low temperature environment, the anemometer and vane of the wind turbine are prone to icing
[0003] In such an environment, the measured data will deviate, which will affect the wind capture rate of the wind turbine, and when the measured data deviates greatly, it will also cause the wind turbine to stop

Embodiment Construction

[0012] In order to better understand the purpose, structure and function of the present invention, a power supply device for a heating system in a wind power generating set according to the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, it is a power supply device for heating system in a wind power generating set according to the present invention. A temperature sensor 1 (PT100) is arranged outside the cabin of the wind generating set to detect the ambient temperature outside the cabin. Temperature sensor 1 (PT100) is connected with the output end of the first surge protector 21 (surge protector 2U), and the input end of the first surge protector 21 is connected with the programmable logic controller 3 ( PLC) signal input terminals (PT100+, PT100–) are connected. The measurement data of the temperature sensor 1 is transmitted to the programmable logic controller 3 (PLC) in the engi...

Abstract

The invention discloses a power supplying device for heating systems in a wind generating set. The power supplying device is characterized in that a switching power supply is arranged between a powersupply and an anemograph and a wind indicator, a second surge protector, and a first surge protector, wherein the switching power supply is used for converting an AC 380V voltage of the power supply into a DC 24V voltage; the second surge protector is located between the switching power supply and the anemograph and the wind indicator; and the first surge protector is arranged between a temperature sensor and a PLC, and the PLC communicates with the second surge protector through a coil of a first contactor. According to the power supplying device, the situation that the anemograph and the wind indicator of the wind generating set are frozen in a low-temperature environment is avoided; and the accuracy of data measured by the anemograph and the wind indicator is ensured, and the wind capture rate and the operation stability of the wind generating set are improved.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a power supply device for a heating system in a wind power generator. Background technique [0002] In a low temperature environment, the anemometer and wind vane of the wind turbine are prone to freezing. [0003] In such an environment, there will be deviations in the measured data, which will affect the wind capture rate of the wind turbine, and when the deviation of the measured data is large, it will also cause the wind turbine to shut down. Contents of the invention [0004] The object of the present invention is to provide a heating system power supply device in a wind power generating set, through the anti-freezing anemometer and wind vane with 24V heating system, the accuracy of the measurement data of the anemometer and wind vane is guaranteed. [0005] In order to achieve the above object, the specific technical solution of the heating system power supply device...
