电网内的多个风电场风速往往因为其地理位置的远近而有着不同程度的相关性，采用Ｎａｔａｆ 逆变换技术即可建立不同风电场之间具有相关性的风速分布样本空间，进而得到具有相关性的风 电场出力。在仿真过程中考虑风速的不确定性，将每个风电场出力视为一个负的满足威布尔随机 分布的负荷，根据历史数据，用方差—协方差矩阵描述不同风电场相关系数，建立最优潮流模型。 最后，在风电接入改进ＩＥＥＥ　３０及ＩＥＥＥ　１１８节点系统中应用蒙特卡洛仿真计算，定量研究随着风 电场之间相关性的增强，最优潮流结果各项指标的波动情况。(Multiple wind speed within the grid often because of their geographical proximity and have different degrees of relevance, Nataf inverse transform using technology to build wind speed distribution between the sample space with different wind farms correlation, and then get relevant The wind farm output. Consider wind uncertainty in the simulation process, the output of each wind farm to meet the load as a negative Weibull random distribution, based on historical data, variance- covariance matrix of correlation coefficients describing different wind farms, the establishment of optimal fashion models. Finally, to improve access to wind power IEEE 30 and IEEE 118-node system Monte Carlo simulation, quantitative research with enhanced correlation between wind farms, OPF result of fluctuations in the indicators.)

随着可持续发展理念的深入，风力发电作为可再生能源得到了快速的发 展。风力发电系统的仿真在风力发电系统分析，发电量分析和电网的能量的 分析中都起到了非常重要的作用。 本文应用 MATLAB 软件，对风速、风轮、传动机构、发电机、与风力发 电相关的电力电子系统建立了数学模型，并进行仿真进方面的研究，得到了 可供分析的仿真结果。介绍了风力发电机组的控制技术，主要是变桨距控制 和发电机变速控制，并利用 MATLAB 软件对变桨距控制系统和低于额定风速 和高于额定风速时的变速风力发电系统进行了仿真。对双馈发电机的解耦控 制进行了仿真。并列举了典型的风力发电系统仿真实例。 (With the wild spread of concept of continuable development ， wind power generation, as a renewable resource, is getting fast development. The simulation of wind power system play a important role in yield of analysis of wind power generation system, the quantity of wind power generation , power generation system. This paper establish wind model, the wind turbine rotor model, drive trains model, induction machine model ， the electric power electron parts of wind power generation model, Then using soft of MATLAB, we realize the simulation. It introduces the control technology of wind turbine, mainly including variable blade pitch and variable speed control of wind turbine. Using Matlab simulate these. And lists an example of practical applying.)

同时使用STM32三个串口的接收与发送，串口1使用printf(),串口2使用u2_printf(),串口3使用u3_printf().接受采用定时器中断超时，5ms未接收到数据认为本次接收结束，置位相应的标志位，主程序检测并处理接收数据。(STM32 simultaneously receive and send three serial, serial port 1 to use printf (), 2 serial ports use u2_printf (), 3 serial ports use u3_printf (). Accepting timer interruption timeout, 5ms does not receive data that the receiving end of this, set the appropriate flag, the main program to detect and process the received data.)

说明：  51单片机的拼音输入法的程序，用C实现，(51 SCM Pinyin input method to the procedures used to achieve C,)
