实现了虚拟同步机的频率控制，可以完美运行(The frequency modulation of a virtual synchronizer is realized)

momic水气两相流,应用LBM BGK模型，模拟了空化泡在近壁区溃灭(momic two phase flow)

计算离散信号的振幅谱和相位谱 1. 编写计算DFT的程序。 2. 编写计算振幅谱和相位谱的程序。 (DSP)

controller based RPM counter

说明：  经验正交函数分解，将给出的数据进行时空分离，便于找出数据的空间分布规律及时间规律(The empirical orthogonal function decomposition is used to separate the given data in time and space, so as to find out the spatial distribution and time rule of the data)

本例程通过matlab提供的simulink水轮机程序，做了改动，调整了部分参数，并且增加了借阅，模仿水轮发电机组一次调频过程，值得借鉴(Through the Simulink turbine program provided by matlab, the routine has been changed, some parameters have been adjusted, and borrowing has been added to imitate the primary frequency regulation process of the hydro-generator set. It is worth learning from.)

说明：  计算电机启动时母线电压暂降的模型 对暂降幅值和相位进行了测量(A model for calculating bus voltage sag during motor starting the amplitude and phase of sag are measured)

example for wavelet analysis using pscad.

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.)

包括15个常用的IEEE电网节点数据，有BPA，清华，IEEE和euro四种格式(it contains 15 power grid IEEE data, there are BPA, tsinghua, IEEE and euro format)
