Photovoltaic automatic weather station

1. Product Overview of Photovoltaic Automatic Weather Station

Photovoltaic automatic weather station is also called photovoltaic environment monitor and fully automatic photovoltaic weather station. The photovoltaic automatic weather station uses a high-stability total solar radiation sensor to monitor the surrounding ambient temperature, wind speed and direction, air pressure, sunshine hours, total solar radiation, Direct solar radiation, solar diffuse radiation, temperature of photovoltaic modules and other indicators. Meteorological environment data is an important indicator for determining solar power generation, and plays a decisive role in the quality of solar power generation; at the same time, it also provides effective data guarantee for the design of solar power stations. It is a standard meteorological environment monitoring station designed and produced in accordance with the meteorological observation standards of the International Meteorological Organization WMO and the IEC (International Electrotechnical Commission) specification standards. At the same time, it also complies with the requirements of relevant content in GB/T 19964 "Technical Regulations for Photovoltaic Power Generation Connected to Power System" and Q/GDW11000 "Specifications for Exchange of Information on Grid-connected Scheduling and Operation of Photovoltaic Power Stations". The meteorological data that the system can monitor include: ambient temperature, ambient humidity, wind speed, wind direction, atmospheric pressure, oblique total solar radiation, horizontal total solar radiation, horizontal direct solar radiation, horizontal solar diffuse radiation, albedo radiation, backplane temperature, Various meteorological data such as peak sunshine hours. With stable performance, high detection accuracy, unattended and other characteristics, it can meet the business requirements of professional meteorological observation.

Photovoltaic automatic weather stations are widely used in real-time monitoring of solar power plants, and provide data protection for the study of solar power generation quality, efficiency, and fault diagnosis data management.

2. Product Features of Photovoltaic Automatic Weather Station 

1. Real-time data monitoring: up to 55 kinds of meteorological data can be collected and analyzed, including ambient temperature, ambient humidity, wind speed, wind direction, atmospheric pressure, oblique total solar radiation, horizontal total solar radiation, and horizontal solar direct Radiation, horizontal solar diffuse radiation, backplane temperature, peak sunshine hours and GPS time, sun altitude angle, sun azimuth angle, sunrise time, sunset time and other monitoring data.

2. Scientific and technological collector: The photovoltaic environmental data collector adopts a new generation of 32-bit MCU processor, and integrates high-precision GPS, GPRS, and Bluetooth digital chips on board, which can accurately correct the collection time and perform high-precision positioning.

3. Wireless data storage: leading wireless storage data technology. The stored data in the photovoltaic data acquisition instrument can be sent wirelessly to mobile phones and PDAs for storage and analysis.

4. Smart data operation and maintenance: adopt advanced cloud data analysis technology, and carry out operation and maintenance level data monitoring and data early warning analysis through GPRS and Bluetooth. It is convenient for on-site personnel to analyze equipment operation and maintenance faults without leaving home.

5. Self-calibration sensitivity: The accuracy of radiation data has a guiding and analytical effect on the power generation of photovoltaic power plants. The accuracy of solar radiation sensors needs to be calibrated and corrected for at least two years in accordance with the requirements of the National Meteorological Metrology Station on "JJG 458-1996 pyranometer" , FT-BGF11 solar power generation environment monitoring instrument can realize automatic calibration and correction of on-site radiation data to ensure the accuracy of radiation data observation.

6. Global tracker: We are equipped with a global self-adaptive fully automatic sun tracker for the direct radiation sensor and the diffuse radiation sensor. This tracker can be used normally in the global range where the south latitude is less than 60° and the north latitude is less than 60°, and the operating temperature range is -40～60°C

7. Green power supply management: The data acquisition instrument can adopt two power supply modes of AC220V and DC12V. And a new generation of green power management module is integrated inside to realize the intelligent switching of AC and DC power supply.

8. Integrated observation bracket: The re-optimized integrated observation bracket makes it easy for field personnel to install and debug equipment quickly, conveniently and simply by one person.
