FDTD_2D_C

模拟产生雷克子波以及雷克子波的振幅谱的matlab源代码。(To simulate the Ricker wave and the amplitude spectrum.)

以IEEE33节点为例，考虑到配电网多为辐射性结构，选用前推回代法， 前推功率，回代电压，该算法通用性强(Taking the IEEE33 node as an example, considering that the distribution network is mostly radiative structure, the forward and backward substitution method is adopted, and the power is pushed forward and the voltage is replaced. This algorithm is universal.)

说明：  线路自动重合闸，三相和单项短路后，又重新恢复正常。(After three-phase and single short circuit, the line will return to normal again.)

电网仿真模型，适合智能电网，配电有源系统的研究开发啊(smart grid for active power distribution system for protection and control)

程序能够完成三相不对称的潮流计算和故障计算(This can complete three-phase power flow calculation and fault calculation)

说明：  三相光伏逆变器孤岛运行，亲测可用，毕设作业(Three phase photovoltaic inverter islanding operation, available)

油田开发效果评价，考虑非均质性的流管法！输入相渗曲线、高压物性资料、渗透率伽马分布等，即可进行油田水驱开发效果评价！(Oilfield development effect assessment, consider the heterogeneity of the flow tube! Input relative permeability curves, PVT data, the penetration of the gamma distribution, oil field water flooding effect evaluation can be carried out!)

说明：  实现两相并网逆变器的SPWM控制,可利用在光伏并网系统中(Realize SPWM control of two - phase grid-connected inverter)

说明：  走向无限、延伸有限薄板状体磁异常正演，直立板和倾斜板，垂直磁化和斜倾斜(Forward modeling of magnetic anomaly of sheet body with infinite strike and finite extension)

说明：  大学电力电子课基本电路 好用的buck电路(buck circuit useful for college student)
