电力系统暂态故障模拟再现系统
说明： 提出并研制了一种新型电力系统暂态故障模拟再现系统。该系统通过将系统发生故障时故障录波器录下的数据转换为符合IEEE的COMTRADE格式文件，经数据处理软件进行分析后由电脑并口送入多功能继电保护测试仪，最终由测试仪还原成故障时的ＰＴ、ＣＴ二次侧电压、电流信号。该系统对继电保护装置参数整定、事故原因查找及分析等有辅助作用。(proposed and developed a new type of power system transient fault simulation and reconstruction system.IEEECOMTRADE. The system of relay device parameter setting, the cause of the accident investigation and analysis of a supporting role.)

牛顿－拉夫逊法潮流计算
基本步骤：
（1）形成节点导纳矩阵
（2）将各节点电压设初值U，
（3）将节点初值代入相关求式，求出修正方程式的常数项向量
（4）将节点电压初值代入求式，求出雅可比矩阵元素
（5）求解修正方程，求修正向量
（6）求取节点电压的新值
（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步
（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)
