Embodiment 1

[0055] The embodiment of the present invention provides a control system for a wind turbine dehumidifier, such as figure 1 As shown, the control system includes: a battery 7, an inverter 8, a first sensor, a second sensor, and a controller 1. Wherein, the first sensor acquires the operating parameters of the power generation equipment in the wind turbine; the second sensor acquires feedback information of the dehumidifier 9 in the wind turbine; the controller 1 acquires the operating parameters and feedback information, according to The operating parameters and feedback information generate power supply start and stop instructions and electrical energy storage instructions; the battery 7 stores the electrical energy generated by the power generation equipment according to the electrical energy storage instructions, or outputs electrical energy to the dehumidifier 9 according to the power supply start and stop instructions; The input end of the inverter 8 is connected with the co...

Embodiment 2

[0067] The difference between the second embodiment of the present invention and the first embodiment is as follows: image 3 As shown, the control system also includes a lighting system 20. The lighting system 20 is connected to the inverter 8. When the inverter 8 has electric energy output, the lighting system 20 starts to work to realize marine lighting.

[0068] In the embodiment of the present invention, two groups of dehumidifiers 9 may be provided, which are respectively arranged in the nacelle and the tower of the wind power generator. Correspondingly, the humidity sensor is also provided with two groups, which are respectively arranged in the nacelle of the wind generator set and the tower of the wind generator set. The lighting system 20 is also provided with two groups, which are respectively arranged in the nacelle and the tower of the wind turbine.

[0069] It should be noted that the number of groups of dehumidifiers and sensors described above is only an example, a...

Embodiment 3

[0071] Embodiment 3 of the present invention provides a method for controlling the dehumidifier of a wind turbine, which is implemented based on the control system of embodiment 1. The control method includes: obtaining operating parameters of power generation equipment in the wind turbine and feedback information of the dehumidifier in the wind turbine; The operating parameters and feedback information generate power supply start-stop instructions and electrical energy storage instructions; according to the electrical energy storage instructions, the electrical energy generated by the power generation equipment is transmitted to the storage battery for storage; and the dehumidifier is controlled to be connected or disconnected according to the power supply on-off instructions. Connection of power generation equipment or / and said battery.

[0072] The system is the basis of the control method. This control method has the hardware basis of the control system described in Embodiment...

Abstract

The invention discloses a control system and a control method of a dehumidifier of a wind turbine generator. The control system comprises a first sensor, a second sensor, a controller, a storage battery and a inverter, wherein the first sensor is used for acquiring operation parameters of power generation equipment in the wind turbine generator; the second sensor is used for acquiring the feedbackinformation of the dehumidifier in the wind turbine generator; the controller is used for acquiring the operation parameters and the feedback information, a power supply starting and stopping instruction and an electric energy storage instruction are generated according to the operation parameters and the feedback information; the storage battery is used for storing electric energy generated by the power generation equipment according to the electric energy storage instruction, or outputting the electric energy to the dehumidifier according to the power supply starting and stopping instruction; the input end of the inverter is connected with the controller, the output end of the inverter is connected with the dehumidifier, the connection of the dehumidifier and the power generation equipment and / or the storage battery are connected or disconnected according to the power supply starting and stopping instruction, According to the system and the method, the ambient humidity working by the dehumidifier is monitored in real time, closed-loop control is carried out on the dehumidifier according to the real-time monitoring data, so that the safety is improved integrally, and the problemsof short service life and resource waste caused by over-use are avoided.

Description

Technical field [0001] The invention relates to the technical field of protection of offshore wind power generators, in particular to a control system and method for a dehumidifier of a wind power unit. Background technique [0002] Offshore wind turbines are in harsh environments with high humidity and high salt fog. In order to extend the service life of internal electrical equipment and structures, after offshore wind turbines are installed in place, they should be installed in the tower’s TUPU (transformer unit and power unit, Dehumidifiers are placed on the transformer unit and power unit) layer and the cabin layer for dehumidification. Before the wind turbines are connected to the grid, the wind turbines need to be installed and debugged. After the wind turbines are connected to the grid, submarine cable faults and grid failures can occur. An independent power supply is set up to supply power to the dehumidifier to ensure that the dehumidifier can continuously dehumidify t...
