摘　　要：送出海缆在海上风电工程中的总投资占比巨大,沿线潮流、电流的分析对其选型起决定性作用,对海上风电工程经济性产生重大影响。提出一种送出海缆潮流及电流分布的快速计算方法,该方法通过一次单向潮流计算即可获得送出海缆各长度处的无功功率及电流。通过与ETAP软件计算结果比较,提出的快速潮流计算方法准确度高,可用于海缆选型。The analysis of current and power flow along the cable is the decisive part for submarine cable selection,so it has a significant impact on the economy of offshore wind farm projects.In this paper,a fast calculation method of the power flow and current distribution along the outgoing submarine cable is presented.The reactive power and current at each point of the outgoing submarine cable can be obtained by once calculation based on one-way power flow.Compared with the calculation results of ETAP software,the fast power flow calculation method presented in this paper has high accuracy and can be used for submarine cable selection.
