| 摘 要： | 针对城轨牵引供电计算现状，即一般将交流系统等效至直流侧进行计算或者交直流侧分开迭代，简化了交直流系统的内在联系，在一定程度上影响计算的精度，探讨了一种基于整流机组模型的城轨牵引供电系统交直流统一的牵引供电计算方法，并采用改进的牛顿-拉夫逊法和高斯-赛德尔法求解，利用10节点直流牵引供电系统进行了验证。提出的交直流统一的牵引供电计算方法已成功应用在城轨牵引供电仿真系统中。

| Abstract: | Traditional power flow for DC traction power supply system usually carries out at DC traction side or executes separately at AC/DC sides,which simplifies the internal relationship and reduces the calculation precision.Through analyzing the model of parallel-connected 12 pulse uncontrolled rectifier,a unified AC/DC power flow for DC traction power system based on improved Newton-Raphson method and Gauss-Seidel method is discussed and applied in 10-node hybrid traction power supply system for practical verifi... |
