Design of micro-automatic weather station for modern power grid based on STM32
With the rapid growth of renewable energy resources over the past few years, the analysis and control of modern power systems are becoming more and more complex. Meteorological information has been regarded as the basic data to help operators handle the problems brought by renewable energy. Thus, the concept of micro-automatic weather station was proposed to meet the needs of modern power grid analysis and control. Based on the STM32 controller and meteorological sensors, the hardware and server software of the micro-automatic weather station are designed and developed, which can monitor wind speed, wind direction, light intensity, temperature and humidity of surroundings atmosphere. All real-time meteorological data together with geographic information offered by Global Positioning System are sent to the base station via wireless General Packet Radio Service network, the networked data are analysed in the server. The real experiment showed that weather station can run smoothly in the natural environment, providing accurate and real-time meteorological data for users. Consequently, micro-automatic weather station makes it possible for researchers to get a large amount of meteorological information at a low price in a short term.
