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...
