With the development and utilization of new energy in domestic and foreign markets, photo voltaic power generation technology has gradually matured and improved. In order to improve the operation stability and reliability of photo voltaic power stations and meet the needs of photo voltaic power generation, the distributed photo voltaic Realizing efficient monitoring of power plants is a problem that power stations need to solve.
Industry Requirements
Need to realize unified operation monitoring of power generation field equipment and centralized management of data;
Realize the analysis of power generation, power consumption and transmission in power stations, and master the quality of energy consumption;
Establish a unified database to provide data services and support for monitoring platforms and other monitoring systems.
Northwest region where solar energy is relatively stable
Solution Introduction
The Fourfaith distributed photo voltaic overall solution uses the Fourfaith Protocol Converter F-DPU100 as the connection device for data transmission and device communication. After the real-time data of the inverter is connected to the protocol converter through RS485, the protocol converter is then operated The 4G network of the merchant sends the data to the cloud server, so that the data is displayed and counted in the monitoring background.
The platform of this solution supports a full set of management services for data collection, power station monitoring, operation, maintenance and operation of new energy power stations such as photo voltaic and energy storage. Through the cloud big data analysis platform, it helps new energy power stations realize core functions such as transparent management, automated operation and maintenance, intelligent diagnosis and auxiliary decision-making. It fully meets the needs of users at all levels in the life cycle of new energy power plants and maximizes the value of power plants.
System functions
System running status monitoring:
The monitoring system monitors the photo voltaic power generation equipment installed by each household in real time, such as the charging voltage and current of each photo voltaic array, battery voltage, and other information, and performs abnormal display and alarm prompts on the fault point.
Inverter power analysis:
The monitoring system displays the collected data in the form of a table or curve, such as drawing and displaying the inverter voltage-time curve, power-time curve, etc., the real-time curve of the input current on the DC side, and the output current curve of the inverter on the AC side, and collecting And display the daily power generation of each inverter and other electrical parameters.
Historical data management:
The monitoring system can save various historical data collected for subsequent system diagnosis. And record various events on the site of household photo voltaic power generation, such as: abnormal communication collection, switch displacement, operation records, etc.
Daily power generation analysis:
The system provides two curve analysis interfaces, real-time curve and historical trend, which can reflect the change of power generation amount on the current day and the specified date before; can compare the same time, analyze the power generation situation; analyze the daily load data chart.
Map Navigation:
You can view the distribution of installed photo voltaic power generation equipment on the map, etc..
Environmental monitoring:
Real-time monitoring of meteorological information of photovoltaic power stations.
Alarm event:
The platform voice, mobile phone message, APP, public account, etc. push the alarm information to the setting management personnel, timely understand the fault information and deal with it as soon as possible.
System Management:
System settings, user rights settings, role settings, etc.
