用于基本的机械领域的飞轮建模分析，熟悉apdl的基本建模技巧(for modling the flywheel by using the apdl)

一个PSCAD的PV光伏系统模型，能完美运行，配合用户系统使用研究。(A PSCAD PV PV system model that works perfectly with the user system using the study.)

本程序为水蒸气物性参数函数源代码。通过它可以方便的进行常用的热力计算。(This program is a function of the physical parameters of water vapor source code. Can easily be used to calculate the heat through it.)

boost电路电压电流双环控制，参数选择(Double loop control of boost circuit)

说明：  先dq变换然后构建电压外环电流内环的双闭环系统，实现了statcom的前馈解耦控制。可以解决大负载投入的电压降落问题。(First, dq transform is used to construct the double closed-loop system of voltage outer loop and current inner loop, which realizes the feedforward decoupling control of STATCOM. It can solve the voltage drop problem of large load input.)

双馈式风力发电机simulink建模，对初学者很有帮助，对风力发电进行模拟(Modeling of doubly-fed wind turbine simulink)

基于MATLAB中的Simulink模块中的双馈风机仿真示例，在此基础上重新设定合理的风机、配网及大电网的参数，设计加入四分量叠加法的风速模型。同时设计了110KV电网电压突然下降，在风电场并网点选择不同模式下的仿真结果分析和35KV配网发生三相短路故障时的风电机组输出特性仿真(Based on the simulation example of the doubly fed fan in the Simulink module in MATLAB, the parameters of the rational fan, distribution network and large power grid are reset on this basis, and the wind speed model with four component superposition method is designed. At the same time, the sudden drop of 110KV power grid voltage, simulation results analysis in different modes of wind farm and dot selection and the simulation of the output characteristics of the wind turbine when the three-phase short circuit fault occurs in the 35KV distribution network)

说明：  建立了风电场模型，可用于多情情况下的风力发电仿真(Established a wind farm model that can be used for wind power simulation in arousal situations)

这个例子显示了家庭能源管理系统在电网电力和分布式电源之间切换。(This example shows a home energy management system switching between grid power and distributed power sources.)

跟prony算法一样，ESPRIT（Estimation of Signal Parameters Via Rotational Invariance Techniques）也是一种参数法，它是一种基于旋转不变技术参数估计的信号处理方法，此方法可以高精度地辨识电力系统中任意组合的衰减/非衰减正弦信号的频率，相位及其幅值等信息。它不需要对信号进行同步采样。此方法把信号空间分解为信号子空间和噪声子空间，能够在较短的信号长度内准确的检测出信号中各个谐波和间谐波成分。(ESPRIT)
