说明：  电网pq控制，pscad，有功功率与无功功率可控(failed to translate)

基于pscad的一个简单的500kv线路故障仿真模型(A simple model of 500kv line fault simulation based pscad)

信号频谱分析 1. 观测已知方波信号、正弦波信号的频谱 分析频率为4KHz、8KHz的占空比为50 的方波信号、正弦波信号的频谱。记录所得频谱图。 观测实时模拟信号（语音）的频谱 用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图(Signal spectrum analysis 1. Observing a known square-wave signal, sine wave signal frequency spectrum analysis 4KHz, 8KHz for the 50 duty cycle square wave signal, sine wave signal frequency spectrum. The recorded frequency spectrum. Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of voice, voice saved as. Wav format. Wav file of the sub-Fourier transform analysis to make. Speech is divided into syllables, it should be sub-analysis, and practical application of digital signal processing of the FFT points is limited, generally only reach 1000 points. Fourier inverse transform IFFT, to restore the signal from the frequency domain. Draw maps and voice waveform spectrum)

支持向量机的画图程序。能够很好的将识别到的不同类型分量，可视化。(Support vector machine (SVM) drawing program. Can very good will to identify the different types of component, visualization. )

用matlab编写的玫瑰动态视图，有助于初学者了解怎么在matlab中实现动态字形和画图函数(Prepared using matlab roses dynamic view, help beginners learn how to implement dynamic glyph in matlab and drawing functions)

PSCAD Model of rectifier for microgrid simulatipon

利用MFC实现的画图程序，能够实现基本图形的绘制，可对基本参数进行设置，还可实现保存和打开。 (Paint program using MFC implementation, to achieve the basic graphics rendering, can set the basic parameters, but also to achieve preservation and open.)

说明：  一个绘制Voronoi图和Delauany三角剖分的程序，并且给出了求凸包的算法。该程序可以演示如何进行三角剖分，帮助你理解整个剖分过程。(a Voronoi diagram mapping and triangulation Delauany procedures, and is seeking a convex hull algorithms. The procedure can demonstrate how triangulation, and help you understand the subdivision process.)

此文件是用来计算电源buck 拓扑 的 MATHCAD 计算文件。(This file is used to calculate the Power buck topology MATHCAD calculation file.)

用了五年多时间打造的基于跨平台开发技术qt开发的图形组态系统，运用模板能组合成任意图元，运用脚本能，定义出图元根据属性的变化，做出相应的动态效果，首先应用于电力系统网路图，监控电网状态。可以应用于实时监控应用领域。超一流的绘制效果，在完成电力系统一次接线图比组态王、三维力控有更好的绘制效果.增加实时数据、web浏览器、后台进程取数，qwt做实时曲线，vista风格等、存成svg文件网上发布，升级到4.6.3等(部分源)(graph )
