Problems solved by technology
[0003] Under normal circumstances, the laying of the submarine cable line adopts a ring topology. Although the ring topology is stable and safe, any wind turbine will be connected to the other two wind turbines. The carrying capacity is far greater than that of its own fan, resulting in a single type of submarine cable selected in the same ring topology in the field, with poor flexibility, and the laying of lines has not achieved optimal results

The invention discloses a line determination method and device for an offshore wind power plant and a medium, and is suitable for the field of line design of wind power plants. The current tail end fan is selected as a first fan, the fan connected with the first fan is selected as a second fan, the accumulated current-carrying capacity of the first fan is determined, and then the model of the correspondingly connected target submarine cable is determined; and determining a line for connecting the first fan and the second fan according to the target submarine cable model and the length of the line for connecting the first fan and the second fan. The accumulated current-carrying capacity is determined by selecting each current tail end fan as a first fan, the corresponding target submarine cable model is determined under the condition that the accumulated current-carrying capacity is determined, and different target submarine cable models are selected for the fans with different accumulated current-carrying capacities in the field, so that the optimal route of the whole field is determined. The situation that a better line result is not achieved due to the fact that selection of the submarine cable model of the ring topology is single is avoided, the flexibility of submarine cable selection is improved, and the better result of line laying is achieved.
Description
technical field [0001] The invention relates to the field of design of wind farm lines, in particular to a method, device and medium for determining a line of an offshore wind farm. Background technique [0002] As wind power comes online at a par, it has strict requirements on the cost and power of new projects. Lines and road laying are the main variable costs that affect the construction cost of wind power projects. The line laying of offshore wind farms mainly uses submarine cables. The selection is affected by the current of the series fans and the ampacity of the submarine cable, and the model of the submarine cable connected between the fans is not a definite value. [0003] Under normal circumstances, the laying of the submarine cable line adopts a ring topology. Although the ring topology is stable and safe, any wind turbine will be connected to the other two wind turbines. The ampacity is far greater than that of its own fan, resulting in a single type of submarin...
