新型直流串联型海上风电场拓扑结构设计
Novel Topology Design of DC Series-connected Offshore Wind Farm
摘要
Abstract
To solve the problem of"abandon wind"in the DC series-connected offshore wind farm nowadays,a novel to?pology of DC series-connected offshore wind farm is put forward in this paper.Firstly,the current-dividing circuit com?posed of two power switches and one inductor is introduced.Secondly,the characteristics of the current-dividing circuit is analyzed.When the power outputs of different wind generators are different,the maximum power point tracking can still be realized by compensating one current through the control of current-dividing circuit.In this way,the power cur?rents of different wind generators can be kept stable,thus the phenomenon of"abandon wind"is avoided.Finally,the feasibility of the topology of DC series-connected wind farm proposed in this paper is verified through simulations.关键词
