上海人工波 需要地震波的朋友可以下来(Shanghai artificial seismic waves need friends can down)

这是分别基于两电平SVPWM和三电平SVPWM的PMSM矢量控制模型，对初学者比较实用，采用matlab2012以上版本打开！(This is based on two level SVPWM and three level SVPWM PMSM vector control model, more practical for beginners! Use matlab2012 or more to open.)

根据体育场馆实测分压分布点数据，绘制风压分布图。(According to sports venues measured pressure distribution points data, draw the wind pressure distribution. )

读取segy文件，消除多次波 的地震处理运用(segy read documents, eliminating the multiple use of seismic processing)

昆仑通态通用版网络版6.2组态软件 无限点破解软件 先安装MCGS6.2组态软件后，把本压缩包内的破解文件覆盖到原安装目录下的Program文件夹里即可(Kunlun universal version of network version 6.2 configuration software infinite point crack software After the MCGS6.2 configuration software is installed, the cracked files in the compressed package can be overwritten in the Program folder of the original installation directory.)

说明：  PLC与安川伺服驱动通讯控制，实现直驱电机的自由分度、点动等多功能运行(PLC and Sichuan Servo Drive Communication Control to Realize Free Indexing and Pointing of Direct Drive Motor)

对于自学者很有用的，大家可以尝试去学习。(it is very improtant.)

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.)
