各向异性q模拟， 适应于地震资料处理反演实验(U-58 Ani Q- Anisotropic Q modeling Yaping Zhu May 2006 Confidential to the Consortium until 1 Aug 2009 Contents of this directory are Matlab packages to perform the following tasks. HomoPlaneAttVTI, Yaping Zhu, complex wavenumber for "homogeneous" plane P-SV wave propagation in VTI media with VTI attenuation Note: "Homogeneous" here means that the real and imaginary parts of the wavevector are parallel to each other. HomoPlaneAttORT, Yaping Zhu, complex wavenumber for "homogeneous" plane P-wave propagation in orthorhombic (ORT) media with ORT attenuation Note: "Homogeneous" here means that the real and imaginary parts of the wavevector are parallel to each other. RotCij, Yaping Zhu, Bond transformation of the Cij matrix (6x6) EffQTI, Yaping Zhu, Effective attenuation- and velocity-anisotropy parameters for finely-layered VTI media composed of arbitrary number of constituents )

说明：  本程序可以建立算法来形成节点阻抗矩阵,利用节点阻抗矩阵来计算短路故障情况下的节点电压和线路电流，程序可供电力系统编程参考。(This program can establish an algorithm to form the node impedance matrix, and use the node impedance matrix to calculate the node voltage and line current in the case of short circuit fault. The program can be used as a reference for power system programming.)

时频重排的程序，做相关研究的可以下载看看，对理解重排原理很有帮助。(time frequency reaarangement)

说明：  自己做的一个框架结构的ABAQUS算例。绝对原创！！！(An ABAQUS example of frame structure)

mathematical model of wind Turbine

说明：  这是一个电力系统无功补偿SVC装置仿真模型，是作者改进的仿真模型，与官方模型略有差别，主体没改。(This is a simulation model of SVC device for reactive power compensation in power system, which is improved by the author. It is slightly different from the official model, and the main body has not been changed.)

说明：  为实现电池储能装置的双向DC-DC变换器，本系统以buck-boost拓扑电路(Battery Energy Storage, Bidirectional DCDC)

说明：  BCUK电路双环PID仿真，实现了电压环和电流环，突然加载测试(Bcuk circuit double loop PID simulation realizes voltage loop and current loop, sudden load test)

说明：  用于计算电力系统潮流，使用了牛顿拉普斯算法，IEEE34 节点系统(Newton raphson algorithm and IEEE34 node system are used to calculate power flow)
