Abstract:

A simulation grid system is developed to achieve frequency tracking,maximum power tracking,phase tracking,input under-voltage protections,output over-current protection,and anti-islanding functions.The Atmega16 high-speed microcontrollers with integrated timer/counter function are used,the fast PWM timer T/C2 is used to achieve SPWM signal generation,and the input capture function of T/C1 is used to achieve frequency and phase monitoring and tracking,and realized the distortion,the input voltage,output current detection and control of other physical quantities.

Key words: grid;MCU;SPWM;DC/AC
