Research on new photovoltaic grid connection device based on Freescale Carle MK60FN1M0 processor and Multi-mode wireless communication technology

Abstract

Design a new photovoltaic grid connection device based on Freescale MK60FN1M0 processor and Multi-mode wireless communication technology. In terms of Modbus protocol, MK60FN1M0 communicates with photovoltaic inverter, the device acquires measurement data such as: DC voltage, DC current, AC voltage, AC current, AC frequency, power of the photovoltaic inverter, and opening-closing state of air switch. These measurement data are stored in real-time in the processor flash. At the same time, MK60FN1M0 is connected with power Multi-mode wireless terminal by UART, to guarantee the acquired measurement data transferred to remote power automation master station according to pre-set Modbus protocol in high speed and high efficiency.
