Anhua Intelligent Micro Grid System
Following with the development of wind and solar off grid system and wind and solar on grid system, a new requirement of load consumption continue growing, efficiency rising and power supply stable comes out. This new system is the intelligent micro grid system. It is also named intelligent distribution power grid system.
2. Application field
This new system is widely used for the below field, and it is using for more new field:
- Some area with high frequency power off but needing stable power supply
- Island and small village
- Some area with good on grid policy or subsidy
- Any area where is suitable for micro grid system
3. Working principle
The system uses the bi direction inverter, battery group, local power grid, wind energy, solar energy and diesel generator to combine a part local power grid. The system will dispatch all of source to feed the power into the power grid , at the same time to realize the off grid output and battery charge function. It ensures the load can be run at any time stable.
4. System features
- Belongs to the intelligent micro grid system
- Bi direction inverter, constant power charge/discharge, constant current charge/discharge, constant voltage charge/discharge. Kinds of battery charge/discharge model option,
- Time section work model adjustable, user can set the work model according to the local power grid characteristics.
- With two way AC terminals, one is for grid power, another is for load, realize the grid tied running and off grid running
- Complete isolation inspection and on/off model change over. When the local power grid is off, the energy storage inverter can be changed to off grid inverter model with any seamless, then get off with the total power grid, realize the running in micro grid system.
- RS485, Ethernet communication option, remote monitor
5. System function
5.1 Grid tied generation
When the local power grid is stable, this machine will charge the rest power of battery bank to the local power grid. The on grid function is controlled and managed by master in real time according to the load condition.
5.2 Off grid converter
When the local power grid is off, the machine will cut off the grid power connection automatic, then turn to off grid inverter model to supply the load. When the local power grid is on again. The machine will finish the phase lock with the local power grid automatic, then turn to the on grid inverter model. No seamless.
5.3 Charge model
When the battery bank's voltage is lower. The master will make the machine turn to charge model automatic, the machine will use the local grid power to charge the battery bank for energy storage.
5.4 Battery and load management
To do the dispatch , monitor and management for all of components
5.5 Remote monitor
To monitor all of running parameters and status
6. The advantages of Anhua Intelligent Micro Grid system
As the leader of this system in China, Anhua will be the first option for the cooperation. Comparing with the same kind of supplier, we have so much advances and advantages
6.1 Rich system integrated experience
- We worked for BTS (GMS) system for over 15 years. In domestic communication field, we take over 55% markets. In oversea market, we have installed this system for different countries, such as Russia, Tajikstan, Iran, India and Phillipines and so on. We have so much experience.
- We have installed so much wind and solar hybrid system in most countries of the world. Only in Nepal, we have installed 8 micro grid power system for the small village use. In north of China, Inner mongolia and Tibet, we together with some famous group installled over 20 power stations
- In China, we are the first company to work on this system. In 2012, we installed a 50kW wind+100kW diesel generator micro grid system for a hotel use in Chile. In 2013 and 2014, we installed some demo system in Sangari offices,Waterfall Estate and Kyalami in South Africa.
- Because of the rich experience and technology preparation, we can reduce the project time as much as we can. This is the important condition for customers.
6.2 Leading technology in this field
6.2.1 Product performance integration and improvement
High integration for each unit. In order to ensure the best RIO , Anhua develops this system with the partners' support, except the above function, we also add the central control, remote option, intelligent dispatch function for this system. It not only reduce the system cost, but also increase the system efficiency.
At the same time, Anhua create the build-in controller module for the bi direction ivnerter, it increase the system efficiency highly.
6.2.2 "One to One " system design
We develop a one to one service model for our customers and partners. We only design the suitable system according to the real condition of each project. We set the optimum working model according to client's local load information and grid feature. We set the priority for all of power source to ensure the best system output and efficiency to increase the income for the customer
6.3 The best system extend
Under keeping the system cost, we keep the best system extend feature. Customer can extends the system capacity according to the system load addition in the future.
6.4 The best system components
For all of the system components, we chose the best one with best quality and suitable price. As the best manufacturer of small and medium wind turbines, we only use our patent pitch controlled wind turbines in this system. And for the battery system, we also use the top brand of Leoch .
Our aim is to provide the best system with the lowest price.
7. System demo explanation
In order to help customer to learn this system well, we enclose a system components and system layout drawing as below. It is a standard micro grid system with 10kW wind turbine and 20kW solar panel
