Village power supply micro grid wind turbine solar integrated system
A. Application field
Oil field energy conservation, scientific research demonstration, communication base station, border guard post, island power supply, forest fire prevention, hydrological monitoring, landscape lighting, seawater desalination, village power supply, etc.
B.Solution plan introduction
This off-grid power station is mainly supplied by three power supply units of wind resource,solar resource and diesel, and other power generation units such as biomass power can be added to ensure 24 hours of uninterrupted power consumption.
This scheme mainly uses renewable energy to generate electricity, focusing on solving the power supply problems in areas without power grid, such as supplying for villages without power, communication base stations, and monitoring equipment etc.

| Name |
Function |
| Wind turbine group |
Use wind resources to generate electricity |
| Photovoltaic module |
Use solar resources to generate electricity |
| Diesel generator |
Start up and supply power when wind / solar generation or stored energy is insufficient.
Usually standby, do not run. |
| Energy store unit |
Store and release electricity |
| Off grid controller |
Convert DC to AC and supply the load |
3. Technical advantage3.1 High rate of new energy generation efficiency and utilization
1) ANE pitch controlled series wind turbines have the features of variable pitch control,high efficiency output, 30% more generation,with good performance in both high and low wind speed area.
2) The wind solar off-grid controller adopts unique technology, and the charging efficiency of the system can reach more than 97%
3.2 Strong ability of customized scheme design
With 11 years of experience in new energy projects, more than 300 wind solar multi-energy complementary power stations designed by us are in continuous operation.
D. Classic cases
1. Off-grid system supply for village without grid in Nepal
1) Site:Madhya pashchimanchal
2)Case photos
3)Site description
The installation site is located in the southern plateau region of the Himalayas, where the average annual wind speed is about 5.7m/S and the average daily sunshine full power is 3.6 hours. The village has nearly 46 households and 186 people.
