高压输电线路中电网故障的pscad仿真模型(pscad simulation model of high voltage transmission lines in a grid failure)

PSCAD基于两端两电平的柔性直流输电模型，对于研究直流输电建模是一个非常好的参考！(HVDC flexible model based on the two ends of PSCAD level, the study HVDC modeling is a very good reference!)

pscad编写风机逆变侧模型包括风机，逆变器。简单实用，可以参考(pscad preparation model includes blower fan inverter side, an inverter. Simple and practical, you can refer to)

CAD批量打印源码程序，例程结合易语言应用接口支持库、拖放支持库、扩展功能支持库，创建Autocad.Application对象，实现CAD对象的属性、方法，可以批量打印。(CAD batch printing source programs, routines combined with easy language support library application interface , drag and drop support libraries , extensions support library , create Autocad.Application object implementing the CAD object s properties , methods, you can batch print .)

自己利用PSCAD搭建的２种PPL锁相环，能够自己调节ＰＩ参数，并与自带的ＰＬＬ进行了测试比较。(PSCAD build their own use two kinds of PPL phase-locked loop to adjust the PI parameters of their own, and with the built-in PLL more)

主要演示Python画曲线的程序，没有太大的用处，只是为了能够下载程序(The main demonstration of Python drawing curve program, not too much use, just to download the program)

可将.txt数据转化为grd数据，用于grads画站点图(.txt data can be converted to GRD data for grads drawing site map.)

恒定声速梯度下的声线模型Matlab作图源程序(onstant velocity gradient model of voice)

Cadence Allegro 中文教程(Cadence Allegro Chinese tutorial)

这是一个阵列校正的程序，通过计算协方差矩阵，利用矩阵元素间的关系计算出阵列的幅相误差(This is an array of calibration procedures, by calculating the covariance matrix, the relationship between the matrix elements of the array to calculate the amplitude and phase errors)
