说明：  给定的运行条件有系统中各电源和负荷点的功率、枢纽点电压、平衡点的电压和相位角。待求的运行状态参量包括电网各母线节点的电压幅值和相角，以及各支路的功率分布、网络的功率损耗等(The set operating conditions included the power of each power source and load point, the pressure of the junction point, the pressure of the balance point and the phase angle.The operation conditions to be obtained included the pressure range and angle of each bus node, the power distribution of each branch, the power loss of the network, and so on)

升压斩波电路（Boost）的仿真 针对 Boost 变换电路，完成以下工作： （1） 在 MATLAB/SIMULINK 下搭建 Buck 电路仿真模型，并设置好各个模块的参数； （2） 分别选择 3 个不同的占空比，用示波器同时观察 E，uGE，i1，io，uo 以及电感两 端的电压 uL和流过电容的电流 iL的波形（注意频率的选择）。(Boost simulation model is built under MATLAB / SIMULINK, and the parameters of each module are set up. (2) Choose three different duty cycles and simultaneously observe E, uGE, i1, io, uo and inductance with an oscilloscope. Voltage UL at End and Current iL Waveform through Capacitor (Attention to Frequency Selection)
