说明：  AD常用元件集成库，基本上的集成元件都有，希望能够有点用吧(Ad common component integration library, basic integrated components are available, hope it can be used a little bit)

It do the decoupled load flow in power system

绪论，介绍了温度控制的发展趋势，发展现状，以及PID控制的相关介绍(the introduction of an article)

STM8S运行LED程序和讲义 流水灯是单片机初学者入门首先学习的一个例程，其作用与地位就如同学习 编程语言时学写“Hello，World”程序一样。流水灯例程的编写就是对 I/O 口的 简单操作， 当知道怎么点亮一盏 Led 灯的时候，恭喜你，你已经能够简单地控制 一款芯片了！(STM8S running water lights LED program and handouts are microcontroller beginners first learn a routine, its role and position is like learning to write to learn programming language " Hello, World" program like. Light water routine is to write I/O port of a simple operation, when you know how lit a Led lamps, congratulations, you have been able to easily control a chip up!)

pic单片机4011串口调试测试程序，适用于初学者。已经过测试。(4011 pic microcontroller serial debugging and testing procedures applicable to beginners. Has been tested.)

电力系统中要求电压稳定度和无功功率满足一定的技术指标，利用带独立直流电源的级 联式多电平逆变器和多电平逆变器最优化谐波台阶式调制技术(OHSW)设计的STATCOM装置， 可以使电力系统中的电压得到稳定以及无功功率和谐波得到有效补偿。本文主要介绍了STAT- COM装置主电路的设计，主电路是STATCOM装置与系统进行交换有功功率与无功功率的环节。 该装置具有输出谐波含量低、损耗小、性能可靠等优点。(Requirements of power system voltage stability and reactive power to meet certain technical specifications, the use of DC power supply with independent level Joint multi-level inverter and multi-level inverter optimized harmonic stepped modulation (OHSW) design of the STATCOM device, Can make the power system voltage stability and reactive power to be harmonic and effective compensation. This paper describes the STAT- COM device main circuit design, is the STATCOM main circuit switching devices and systems for active and reactive power component. The device has a low output harmonic content, low loss, performance, and reliable.)
