Offshore wind power collection system optimal design method considering electromagnetic environment constraint

Abstract

The invention relates to an offshore wind power collection system optimal design method considering electromagnetic environment constraint. The method comprises the steps that (1) according to wind power plant fan coordinates, submarine cables and electrical equipment data, partitioned optimization is performed on a collection system; (2) the topological structure of the collection system after partitioned optimization is optimized, full-life-cycle cost C is used as an objective function of an optimization model, magnetic field limitation conditions are set for constraint, and multiple alternative optimization schemes are acquired; and (3) an electromagnetic pollution overall range of the collection system under each alternative optimization scheme and different constraint gradients is calculated, multi-party gaming assessment is performed on the multiple alternative optimization schemes, and an optimal scheme is obtained finally. Compared with the prior art, the method has the advantage of realizing an optimal plan with economy, environmental friendliness and reliability.

Description

technical field [0001] The present invention relates to the field of optimal design of offshore wind power collection systems, in particular to an optimal design method for offshore wind power collection systems considering the constraints of the electromagnetic environment. Background technique [0002] Offshore wind farms are rich in resources, have a high power generation time, and are suitable for large-scale development, and have become the focus of renewable energy development. With the increase of development intensity, the number of offshore wind farms is increasing all over the world, and the scope of site selection is gradually pushed to the far sea, and its installed capacity, cable transmission power, and voltage level have all been significantly improved. In the long run, it is an inevitable trend that the number and capacity of offshore wind farms will be greatly increased, and the resulting marine ecological imbalance cannot be underestimated.

Problems solved by technology

[0005] Most of the existing research on offshore wind power collection systems is from the perspective of economy and reliability, and the problem of submarine cable magnetic disturbance caused by the rapid development of offshore wind farms is not fully considered in planning. my country's offshore wind power is in a period of blowout growth. After many large and super large offshore wind farms are put into operation in the future, it is urgent to carry out relevant quantitative research and establish an accurate mathematical model on how to balance the optimal economic benefits and the sustainable development of the marine environment, so as to provide reference for the environmentally friendly construction of offshore wind farms
