摘　　要：迭代通量线方法是一种被广泛应用于求解高压直流输电线路下离子流问题的方法,在每根流线上需要求解一个多变量的最小二乘优化问题。该文从迭代通量线方法出发,结合递推格式将每根流线上问题简化为单变量优化问题,从而使得通量线方法的计算规模被大大减小。实验表明,该文所提方法能够有效提高求解效率和在不同初值下的鲁棒性。该文提出的低阶迭代通量线方法能够有效应用于具有复杂几何结构的离子流模型。The flux tracing method is widely applied to solve the ion-flow field problem of the HVDC transmission line model,which transforms the original boundary value problem into the least square problem along the flux line.In this paper,an improved flux tracing method is proposed.The multi-objective optimization problem in the original method has been simplified to a single-objective optimization problem by applying the recursion scheme.Numerical experiments show that the proposed method has significantly improved the efficient and stability,which can be effectively applied to ion-flow models with complex geometry structures.
