SAVE UP TO 30% ELECTRICITY ENERGY SUPPLY FOR BTS STATION IF APPLYING THIS SOLUTION

One day a BTS station consumes about 30kwh, with more than 100,000 stations today, the BTS stations spend more than 10 billion VND on electricity a day. This number is not small and if applying the below solution will save a lot of power consumption for BTS.

How do telecom service providers find energy saving solutions and alternative energy sources to reduce their investment costs on electricity? There are two solutions currently proposed: Using clean and endless power from using wind turbines and solar batteries.

 

1. Using wind turbine to directly supply AC power to BTS

- This system uses wind power and the national grid to supply power to the BTS station. The power grid connected to the Inverter AC IN is responsible for two main tasks: providing power to the load at the BTS station while charging the battery into backup storage when power is cut.

- Skystream wind turbine is directly connected to AC OUT power from inverter; When there is good wind, wind turbines supply electricity for use, if the load is not used up, the excess energy will be sold back to the grid (if using Grid Grid tie type) or used to support charging battery in reserve system. This will reduce the electricity bill very seriously every month for investors.

- When the power grid is cut, the BTS will use redundant power supplied by the batteries. The wind turbine takes AC power from inverter, so it still works normally and power back to load and charge for battery if there is excess energy.

- So when designing enough capacity, this system will operate continuously despite frequent power outages. At the same time, a lot of cost is saved for reducing the use of grid electricity for BTS.

- In case of low battery reserve and low wind power, there is not enough power to supply for the station when the grid is out. So the backup system should have an extra generator to supplement the case that clean energy source is not enough for BTS to operate.

- With this system, the equipment in the station can operate 24h / 24h but the cost of electricity payment is reduced significantly.

 

2. Supply DC power to BTS system with wind turbine and solar battery

- Power supply system for BTS including national grid power and wind power system combined with solar energy. This clean power source system provides DC power to fully charge the batteries.

- The system will use the grid connected to AC INPUT of the Inverter to support in supplying AC power for the load and battery charger in the station.

- Energy source from wind and sun combine charging to battery, this DC power continues through inverter to be converted into AC source to provide active load. The electricity grid supply only adds to the clean energy source, when this supply is not enough to supply for the load to operate. Or the electricity grid supply only works to maintain the system, so it will save the monthly electricity costs.

- Using the combined energy source of wind and sun will take full advantage of these two types of energy and limit their disadvantages.

- When the power grid is cut, the system will use the reserve power. PV panels and wind turbines operate and fully charged for batteries. Inverter takes DC power to convert it into AC power for active load. If both wind and solar energy sources are not enough, the station system can add 1 backup generator. This will ensure a 24-hour operation station system that saves a lot of electricity costs and precious fuel sources to run generators.
