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.
2、 Product Description
This model meets the national standard requirements, complies with the latest data requirements and logical correspondence of the photovoltaic power station submitted to the provincial survey, and supports secondary upgrades of new parameters in the future. We use a highly stable solar total radiation sensor with cosine characteristics, fast response, zero offset, and wide temperature response to ensure accurate and stable radiation data.
Our company has rich experience in serving domestic and foreign photovoltaic power plant users for many years, with sufficient sensor inventory, complete production lines, mature instrument and equipment debugging technology capabilities, after-sales tracking services, and a fast logistics transportation system.
3、 Typical applications
1. Solar photovoltaic power generation and solar energy resource assessment
2. Monitoring of solar energy systems and research on atmospheric energy balance
3. Calibration and validation of solar radiation data obtained from satellite inversion
4. Research on thermal stress, heat exchange, and climate change
5. Initial estimation and processing of light resources for power plants, revenue evaluation
4、 Implementing standards
The site selection of a distributed photovoltaic power generation environmental monitoring system needs to consider many factors, and the site should be established in an unobstructed area from sunrise to sunset throughout the year.
Our company provides detailed and professional guidance documents for personnel related to photovoltaic power plants based on international observation methods, national observation standards, power industry standards, and years of rich experience in on-site site selection, environmental monitoring system installation and commissioning.
