电力系统工具包(PST)的最新版本3.0，以及英文说明，它最大的优势在于扩展性强，已经在电力系统获得较为广泛的应用(Power System Kit (PST) The latest version 3.0, as well as in English, it is the biggest advantage of strong expansion, has been in power systems get more widely used)

计算多跨连续梁内力并绘制弯矩图，计算书度快且准确(inner force calculating)

本程序时基于混沌理论和ELMAN神经网络的短期负荷预测，能取得很好的预测效果，直接使用该程序就能实现电力短期负荷预测，同样使用于其他类型的时间序列预测(the procedures based on chaos theory and neural networks ELMAN short-term load forecasts, can be achieved very good results forecast, the direct use of the procedure we will be able to realize short-term power load forecasting, the same used in other types of time series prediction)

一个access vba的源码，功能为根据读取xml，csv来实现数据分析，并保存到access db，生成报表，支持预览及打印功能，是用日语做的，说明书以及操作用的xml，csv也包含其中。(An access vba source code, function according to read xml, csv to data analysis, and save it to access db, generate reports, preview and printing support is done in Japanese, manuals, and operating with the xml, csv also included.)

说明：  Matlab显式三维地震数据的源代码，从事地震勘探研究的同行可下载，很方便(Matlab explicit three-dimensional seismic data of the source code, engaged in seismic research peer can be downloaded, it is convenient)

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.)
