| Abstract: | Based on AVR MCU ATmega16,a design scheme of an intellectualized controller is presented for dual sources automatic transfer switches with circuit-breakers in heavy-loaded distribution systems.The on-chip peripherals of the micro-controller are used adequately by measuring the voltage of the sources with its A/D converter,measuring the frequency and phase order of the sources by input capture and external interrupt function,connecting LED display driver with SPI interface.Critical parameters are set by panel and stored to the on-chip EEPROM.The status detection and driving control of circuit-breakers are performed by parallel interface with optical coupling.The reliability of the controller is enhanced by taking several measures both in hardware and software to prevent electromagnetic interference. |
