Photovoltaic -- micro-grids solution
A. Pain point analysis
B. System structure introduction
SEIS Micro-Grid - Solar power distribution system is an integrated system of Internet + solar power generation + an integrated system for prepaid electricity sales; the whole system has high reliable performance, long service life, no pollution to the environment, and can generate electricity off the grid. Electricity sales can be paid for by customers online or offline.
SEIS Micro-Grid - The Solar management system monitors and controls the data of the equipment on the power generation side and the power sale side in a platform system in real time, which is convenient for users to effectively manage.
On the generating side: Real-time monitoring of inverter voltage, current, frequency, real-time power generation, daily power generation, monthly power generation, annual power generation, cumulative power generation, etc. BMS management system for energy storage battery charge and discharge status, voltage, current, SOC, limited monitoring of operating status, etc. Protect the battery against the impact of excessive discharge on the battery life. An alarm is generated when the remaining battery capacity is less than 30% (configurable) of the capacity on rainy days. You can start the backup diesel generator to ensure power consumption. Has a powerful alarm function, equipment failure will be real-time alarm.
On the electricity sell side:prepaid meter with standard STS protocol,to ensure the safety of electricity sales,to the user file management and electricity sales management,all sales data for statistical analysis and query at any time; The meter with communication function can monitor the electricity consumption of each user in real time, monitoring voltage, current, power, electricity and so on. The meter with safety protection function, automatic power off over current (current can be set), buzzer alarm on insufficient remaining power, automatic power off to solve the problem of charging.
The data on the power generation side and the power consumption side can be compared and analyzed, so that the owner can clearly grasp all the data to provide data basis for the benign operation of the entire system, and better manage the system and serve the user.
C. Function introduction
1. User-friendly interface and mobile App support:
Providing Web and mobile APP client access mode, convenient for users anytime anywhere checking power station status, receiving alarm information, and executing remote control commands.
2. Profile of station points:
Display detailed information from each of distributed photovoltaic site, including geological location, installed capacity, historical power generating records and etc. Combined with meteorological data (weather reports, actual sunshine duration and etc.), analyzing the effects from environmental factors to power generating amount, which contribute to design optimized plant layout and accurate prediction of future generation.
3. real-time data collection and demonstration:
Real-time monitoring and record the running parameters from all facilities in photovoltaic power stations, such as Voltage, current, power output from photovoltaic set, environmental temperature, sunlight intensity and etc. According to these data, form all kinds of statistical forms. DD/MM/YY statistics of total power generation, comparative analysis of power generation efficiency and equipment performance evaluation.
4. Remote control and optimal management:
Users are able to adjust the work mode via Cloud remote control managing power station equipment for better power generating efficiency and sunlight use ratio. With remote control, we can realize the remote power on/off on the key equipment like inverter, parameter setting changing and etc.
5. Intelligent malfunction early warning and diagnostic:
Automatically recognize and rapid respond to abnormal status happening in the system, such as malfunction on inverters, over-voltage, under-voltage, over-temperature and etc. It inform users by sending them message, E-mails or by APP. Also it will remotely analyze the failure cause and provide the initial diagnostic report&maintenance proposal.
6. Safety and authority managements
Multilevel authority limits setting, users with different roles can view and operate different function modules. Data encrypted transmission and storage, securing the safety of data from running power stations.
According to all had said upon, intelligent photovoltaic monitoring&maintenance Cloud service platform is a crucial tool to run the photovoltaic power station effectively, with automatically monitoring, intelligent diagnostic, data analysis and other functions to one.The platform has effectively increase the maintenance efficiency and economical benefits for photovoltaic power station.
D. products introduction
E. Conclusion for solutions
By photovoltaic-- micro-grid solutions, we solve the problems of not enough power for each users and no power available, greatly reduce the housework burden for families and efficiently increase the living quality of users. At night power is supplied by storage batteries to make sure that each user can have electricity. When comes to continuous rainy days, the backup diesel generator can directly supply the power and recharge the storage batteries, prolonging battery life and making sure that users have electricity.
