1. Scope of Application
Distributed photovoltaic power generation refers to the photovoltaic power generation facilities that are built and operated on the user's site or nearby, with the characteristics of self-consumption on the user side, surplus electricity on the grid, and balance regulation in the distribution network system.
In order to ensure the normal operation of the photovoltaic power station and data analysis, it is usually necessary to equip the distributed photovoltaic power generation environmental monitoring system to monitor the total solar radiation, ambient temperature, wind speed and direction, photovoltaic module temperature and other indicators.
The distributed photovoltaic power generation environmental monitoring system can be connected to the monitoring system, which can display, record and analyze the data of the environmental monitoring system, and it can also be connected to the inverter control system, which can analyze the sensor data by the control system to ensure the effective operation of the photovoltaic power station.
2. Product Description
The model meets the national standard requirements, conforms to the latest data requirements and logical correspondence reported by the provincial dispatching of the photovoltaic power station, and supports the secondary upgrade of new parameters. The high stability solar total radiation sensor is used, which has perfect cosine characteristics, fast response, zero offset and wide temperature response performance, ensuring the accuracy and stability of the radiation data.
Our company has many years of experience serving photovoltaic power station users at home and abroad, with a full range of sensors in stock, a complete production line, mature instrument and equipment commissioning technology capabilities, all-round after-sales tracking services, and a fast logistics transportation system.
Three, typical applications
1. Photovoltaic power generation from solar energy, assessment of solar resources
2. Solar energy system monitoring, atmospheric energy balance study
3. Calibration and verification of the solar radiation data retrieved from satellites
4. Thermal stress research, heat exchange research, climate change research
5. Initial light resource estimation and revenue assessment for power stations
IV. Implementation Standards
The site selection of the distributed photovoltaic power generation environmental monitoring system needs to consider many factors, and the site should be established in a place that is not obscured from sunrise to sunset throughout the year.
Our company provides detailed and professional specification guidance documents for personnel related to photovoltaic power stations based on international observation methods, national observation specifications, power industry standards, and years of rich on-site site selection and environmental monitoring system installation and commissioning experience.
