AI Technical Summary

Technical Problem

In the line laying of offshore wind farms, the existing technology adopts an annular topology, resulting in single selection of submarine cable models, poor flexibility, and failure to achieve better line effects.

Method used

Using a tree topological structure, by selecting the current end fan in the field as the first fan and the connected fan as the second fan, the cumulative current carrying capacity of the first fan is determined according to the initial fan and the connection method, and the target submarine cable model is determined based on the cumulative current carrying capacity, and the optimization route of the entire field is gradually determined.

Benefits of technology

By selecting different target submarine cable models between fans with different cumulative current carrying capacity, the flexibility of submarine cable selection is improved to ensure that the line laying achieves better results.

Abstract

The present invention discloses a method, device and medium for determining the line of an offshore wind farm, which is applicable to the field of line design of a wind farm. The current terminal wind turbine is selected as the first wind turbine, and the wind turbine connected to the first wind turbine is selected as the second wind turbine, and the cumulative current carrying capacity of the first wind turbine is determined, and then the corresponding target submarine cable model is determined, and the line connecting the first wind turbine and the second wind turbine is determined according to the target submarine cable model and the line length connecting the first wind turbine and the second wind turbine. The cumulative current carrying capacity is determined by selecting each current terminal wind turbine as the first wind turbine, and the corresponding target submarine cable model is determined when the cumulative current carrying capacity is determined. Different target submarine cable models are selected between wind turbines with different cumulative current carrying capacities in the field, so as to determine the preferred route of the entire field. Avoid the single selection of the submarine cable model of the ring topology, which leads to the failure to achieve a better line result, improve the flexibility of submarine cable selection, and achieve a better line laying result.
