The two ends of the first retractable cable 7 are respectively fixedly connected to the floating platforms 6 of the two adjacent wind turbines 2. The first retractable cable 7 can be retracted and adjusted to cope with the water surface fluctuations caused by ocean waves.

[0039] The photovoltaic breeding area is arranged in the circular area formed by the wind farm area, with a side length of 136m to 450m.
