【 摘 要 】

In order to explore the factors that affect the reliability and cost of the collection grids, we consider the ring topology of collection grids for offshore wind farm. Reliability evaluation model and cost model considering the connection among the cables, switchgears and wind turbines were established according to switch configuration scheme. The reliability and cost were contrasted of the partial switchgear configuration and the complete switchgear configuration of ring topology. On this basis, when the number of switchgear is unknown the reliability evaluation model and cost model of the partial switchgear configuration are established. Considering the reliability and cost, the NSGA-II algorithm is used to achieve the Pareto optimality, and the optimal partial switchgear configuration scheme is designed.
