本程序用来模拟测量交流电的周期，频率，功率，峰峰值等参数，先运行mdl文件，模拟出变化的交流电压和电流值，再运行.c文件，测量电压和电流的各项参数。-This procedure used to simulate the measurement of alternating current cycle, frequency, power, peak-peak and other parameters before running mdl file, simulate the changes in AC voltage and current values, and then run. C files, measuring voltage and current parameters.
