2009年全国大学生电子设计竞赛本科组A题C语言程序，使用C8051F120单片机，光伏并网逆变器模拟-2009 National Undergraduate Electronic Design Contest Undergraduate Group A title C programming language, use the C8051F120 MCU, photovoltaic inverter simulation

光伏并网的程序，是2009年全国电子设计的题目，当时这个获得了一等奖-Photovoltaic process, is the Electronic Design 2009, the title, won first prize at the

该源码主要是用于检测电网中电压信号的频率和相位信息，在光伏并网中必须要将信号的频率和相位分别调至50HZ，相位必须同相才能保证能够安全地输入电网，此程序能够跟踪逆变电压的相位频率信息，方便接入-The main source of information for the frequency and phase detection grid voltage signal must be in the photovoltaic grid frequency and phase signals wer
