[0002] With the growing global demand for clean energy, offshore wind power, as an important renewable energy source, has become an important part of promoting green development in various countries. In offshore wind power systems, converters, as the core equipment connecting wind turbines to the power grid, play a vital role. The main function of the converter is to convert the AC power generated by wind turbines into DC power or AC power of a specific frequency suitable for grid access, thereby ensuring the stability and efficient operation of the wind power system. However, offshore wind farms are usually located in marine climate environments and face extremely harsh working conditions. Marine climates are characterized by high humidity and large temperature differences. Especially at night and in the early morning, with the rapid change of temperature, condensation is easily formed inside the converter. On the one hand, this condensation phenomenon may cause the performance of electrical components to deteriorate.

[0038] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0039] Figure 1 is a schematic diagram of an exemplary implementation of an anti-condensation method for an offshore wind power converter shown in the present application, such as Figure 1 As shown, the anti-condensation method for the offshore wind power converter comprises the following steps:

[0040] S101, based on a temperature sensor and a humidity sensor installed inside a converter of an offshore wind turbine generator set, respectively obtain temperature data and humidity data corresponding to the converter.

[0041] A temperature sensor and a humidity sensor are installed inside the inverter. The temperature sensor can detect the temperature of the internal environment of the inverter, while the humidity sensor can monitor the humidity level in the air.

[0042] S102: Determine whether the inverter triggers an anti-condensation condition according to the temperature data and / or the humidity data.

[0043] S103, in response to determining that the inverter triggers the anti-condensation condition, starting a fan installed inside the inverter, and starting a condenser installed inside the inverter, the condenser being used to condense moisture inside the inverter into water and discharge the moisture out of the inverter through a drainage device.

[0044] When the judgment result shows that the internal environment of the inverter has triggered the anti-condensation condition, the fan and condenser inside the inverter are started to work together. The fan accelerates the air flow to help discharge moisture, while the condenser condenses the water vapor in the air into water droplets through cooling. These water droplets are then discharged from the inverter through the drainage device, thus avoiding condensation damage to the electrical components inside the inverter.

[0045] The embodiment of the present application can effectively prevent condensation problems caused by excessive moisture inside the inverter of an offshore wind turbine unit by intelligently monitoring temperature and humidity data and starting fans and condensers to work in conjunction. This not only improves the reliability and service life of the equipment, but also helps to reduce maintenance costs and improve the overall operating efficiency of the wind farm.
