Abstract
In view of the common problems of intelligent controllers for photovoltaic small low-voltage intelligent circuit breakers in distributed photovoltaic scenarios,such as poor anti-interference performance of analog quantities,low system stability and weak communication reliability,an overall solution for product function integration based on STM32 and realized through modular programming is proposed.The solution fully utilizes the hardware multiplier of STM32 to efficiently support a large number of multiplication operations in digital filtering algorithms,effectively suppressing fixed interference and random noise,and improving the speed and accuracy of signal processing.Meanwhile,system stability is enhanced through measures such as watchdog timer and hardware monitoring.RS-485 communication is adopted,with status monitoring and alarm functions,presenting a high cost-performance ratio.The photovoltaic small low-voltage intelligent circuit breaker equipped with this intelligent controller has been verified through on-site commissioning,and its performance indicators have met the expected targets.关键词
