【 Model recommendation: TH-FGF9, a manufacturer of meteorological and environmental monitoring instruments and equipment. Yunjing Tianhe supports customized services for merchants. You can rest assured when choosing Shandong Yunjing Tianhe. 】 Application of distributed photovoltaic meteorological stations - real-time monitoring and data analysis to optimize the layout and operation strategy of photovoltaic power stations. High precision measurement uses first level solar radiation sensors, platinum resistance temperature probes, ultrasonic anemometers, etc., ensuring a data error rate of<1%. Distributed deployment of multiple meteorological monitoring stations in different locations of photovoltaic power plants, forming a distributed monitoring network to improve the accuracy and timeliness of monitoring. Real time monitoring and data transmission can monitor changes in meteorological elements in real time and transmit data to data processing centers or remote monitoring platforms in real-time. Operation and maintenance personnel can view meteorological data anytime and anywhere, and timely understand the operating status of photovoltaic power plants. Low power consumption and long endurance use solar power modules and intelligent power management, combined with lithium batteries, can maintain power supply for 3-5 days in continuous rainy and cloudy days, without the need to connect to mains power, suitable for scenarios without grid access such as roofs and greenhouses. The high protection level sensor housing is made of corrosion-resistant and dust-proof materials, and the circuit design incorporates an anti electromagnetic interference module to ensure the authenticity and reliability of the data. At the same time, the device has an IP65 protection level and can operate stably in harsh environments.

1、 Scope of application

Distributed photovoltaic power generation refers to the photovoltaic power generation facilities that are built and operated at or near the user's site, with the user's self use as the main feature, excess electricity connected to the grid, and balanced and regulated in the distribution network system.

In order to ensure the normal operation and data analysis of photovoltaic power plants, it is usually necessary to equip a distributed photovoltaic power generation environment monitoring system to monitor indicators such as total solar radiation, surrounding environmental temperature, wind speed and direction, and photovoltaic module temperature.

The distributed photovoltaic power generation environmental monitoring system can be connected to the monitoring system, which displays, records, and analyzes the data of the environmental monitoring system. It can also be connected to the inverter control system, which analyzes the sensor data to ensure the effective operation of the photovoltaic power station.
