| 摘要: |
| 为解决常规潮流求解条件刚硬,可能导致迭代不收敛或计算结果不合理的问题,提出了电力系统柔性潮流的概念、模型和算法,推导了包含发电机静特性及负荷静特性描述的直角坐标牛顿一拉夫逊法柔性潮流雅可比方程,给出了基于负荷和发电机基点功率的一次潮流和二次潮流计算流程.柔性潮流雅可比方程的个数恒等于系统阶数的2倍且结构保持不变.柔性潮流不仅可得到节点电压幅值和相角,还可给出系统频率以及负荷和发电机的实际功率.与常规潮流相比,柔性潮流不再需要设置平衡节点、PV节点和PQ节点,其收敛性好且求解过程和结果更加符合电力系统工程实际.算例系统验证了柔性潮流模型和算法的正确性. |

| Abstract: |
| The idea,model and algorithm of FPL(Flexible Power Flow) technique are proposed to avoid the rigid conditions of conventional power flow solution which may lead to nonconvergent iteration process and unreasonable computation results.The rectangular Jacobian equations of Newton-Raphson FPL are deduced,including the description of generator and load static characteristics,and the calculation process of primary and secondary power flow is given based on the base-point power of load and generator.The number of ... |
