Problems solved by technology

[0002] Offshore wind power construction is difficult, maintenance costs are high, and the environment is relatively harsh. For a long time, an important factor hindering the development of offshore wind power is technology and cost. Traditional solutions have high costs and poor economic benefits.
[0003] As an important equipment in the offshore wind power system - offshore wind power step-up dry-type transformer, because it is installed in the tower, it is difficult to dissipate heat. It needs to be equipped with an external circulating cooling system for heat dissipation. The low temperature design of the transformer itself, anti-corrosion design and The long-life design of the heat dissipation system leads to high costs. Due to the lack of a complete control system for the cooling system, the transformer and its external circulation cooling system need regular maintenance, which further increases the cost of offshore wind power operation and maintenance.
The offshore wind turbines work all year round based on the natural wind force. The size and direction of the wind are irregular and unstable, so that the output energy of the generator changes continuously. At present, there is a lack of a method that can be reasonably distributed according to the heat generated by the transformer. Control System of Running Time of Power Parts in External Circulation Cooling System
Due to the special operating environment of offshore wind power, the operation of transformers is in a state of unmanned monitoring, and it is difficult to control real-time data
