| 摘 要： | 由于城市轨道交通直流供电系统建模后表现出非线性特性,对模型求解的仿真算法大都基于迭代技术。文章介绍了双重线性迭代和牛顿迭代两种算法,并从收敛效果和快速性两方面对它们进行了测试对比分析,同时通过改变电路结构模型和选用合适的迭代算法得到了理想的仿真效果。

| Abstract: | Because of the nonlinearity of DC power supply system model for urban rail transportation,most simulation algorithms for model are based on iterative techniques.In this Paper,two kinds of iterative methods namely Newton-iterative and Double-linear iterative are presented;they have also been tested and compared with respect to convergence effect and rapidity.By changing the circuit structure model and selecting suitable iterative algorithms,the ideal simulation effect will be obtained. |
