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.)

管道缺陷计算程序
采用ANSYS软件的APDL语言编写的两个命令流文件,用于计算含缺陷管道的失效概率,将参数稍作改动,可用于其它结构的可靠性分析(Two command stream files written in APDL language of ANSYS software are used to calculate the failure probability of defective pipeline. The parameters can be changed slightly and can be used for reliability analysis of other structures.)

煤矿信息管理系统是基于SuperMap Object,使用 C#语言开发的煤矿信息管理系统
系统主要实现煤矿信息的管理,包括属性数据和图形数据的管理。其中最重要的部分是钻孔数据的管理,
比较理想的解决了钻孔数据的查询、浏览、修改、添加、删除和导出,并着重实现了钻孔剖面示意图的自动绘制,
此外还实现了计算机图件的管理、地图数据集导出、地图输出打印等功能。(Mine information management system is based on SuperMap Object, using the C# Language developed by the Information Management System for Mine realize mine of information systems management, including the attribute data and graphical data management. One of the most important part is the management of borehole data, a more satisfactory solution to the borehole data query, browse, modify, add, delete and export, and focus on the achievement of the drilling section diagram of automatic drawing, in addition to realize a computer management maps, maps derived data sets, maps output printing.)
