摘　　要：提出了一种用于配电网快速潮流计算和仿真信息可视化的新方法:结合十字链表与关联矩阵,给出了阻抗矩阵自动生成算法,并可以任意顺序求解各支路电流和各内节点电压;提出了基于right-looking LU分解法的并行高斯消去算法,利用GPU(图形处理器)加速求解复系数回路阻抗方程组;采用GIS(地理信息系统)和虚拟现实技术,对潮流计算结果进行仿真可视化.仿真算例表明,该方法对节点编号无特殊要求,适用于有环、无环的配电网潮流计算,具有计算速度快、精度高、仿真结果显示直观形象的优点.A novel method of the power flow calculation and simulation information visualization was proposed for simulating quickly and vividly the operation status of distribution systems.On the basis of the orthogonal list and incidence matrix,an impedance matrix formation algorithm was not only designed to automatically calculate every matrix elements,but also each branch current and each internal node voltage were computed with arbitrary sequence;a parallel Gaussian elimination algorithm based on right-looking lower-upper（LU） factorization was put forward,in order to accelerate the complex coefficient loop-impedance equations solving by graphic processing unit（GPU）;geographic information system（GIS） and virtual reality technologies were used to visualize the result of power flow calculation.Simulation examples show this method hasn＇t special requirement for the node numbering scheme and is suitable for power flow calculation of the radial and the meshed distribution networks for its rapid computation,high precision,visual and intuitive display about simulation result.
