DLLD have been awarded many advanced patented technologies and commend in China, such as the “First Prize of Invention of Micro Hydro Generator for Rural Users” by Yunnan Provincial Science and Technology Commission in 1991; “Excellent Project Award of Agricultural Science and Technology” by the State Science and Technology Commission in 1996; “China Rural Energy Industry Association” in 2002. In 2002, China Rural Energy Industry Association “China Rural Energy Small Power Supply Industry Excellent Product Award”, and so on. DLLD Power passed CE certification in 2001 year and have been export to United States, Britain, France, Lativa, Peru, Chile, Indonesia, Guinea, Russia, Congo and Southeast Asia, etc other 60 countries like more than 20 years. Our products are well popular by the users because its stable performance and free maintenance.

Why micro-Hydropower?

Electricity from micro-hydropower is a clean, safe, emission free, renewable energy. With proper development it is reliable, requires low maintenance, and results in a lower cost per kW than other options such as: gasoline, diesel, or wind generators, solar photovoltaic (PV) panels, or the environmental damage and/or expense of bringing the grid from afar. Community participation, self-sufficiency, and the benefits of reliable lights bring pride, stability, and unity to communities. Power can be used for lights, radio, TV, computers, small industry (sewing machines, agricultural processing), and large community water heaters. Especially benefited are women and children who no longer face the smell, smoke, danger, inconvenience, and cost of lanterns. A consistent water supply allows power generation 24 hours/day even when there is no sun or wind. The generating equipment produces low noise and can be built so it is not obstructive or abusive to the environment. Water use is “non-consumptive” in that the water flowing through the turbine returns to the river or stream it originated from and can be reused for agricultural irrigation purposes.

DLLD Micro Hydro Systems Advantages

1. Small size, lightweight, and reasonable integrated design, for the stand-alone system we use rare earth permanent magnet synchronous generator for super-reliable performance and simple structure. For on-grid usage, we can use the asynchronous generator.

2. Equipped with automatic voltage and frequency regulation control function, our ELC controls the electricity for the generator and sends the excess electricity to a dummy load fully. Take an example, if the load loss is 20%, our thyristor will automatically balance this 20% load by itself fully to keep the voltage stabilization.

3. DLLD hydroelectric equipment can be output AC power directly to be used as a power source for lighting, watching TV, and dragging micro agricultural and by-product processing machinery for farmers. Also could be stored in the battery for peak usage.

4. DLLD combines a micro water turbine, generator, voltage, frequency stabilization controller, etc. integrated together, with reliable performance and low maintenance cost, which also increase the lifecycle by 20-30 years.

5. Our micro-hydropower system is an environmentally friendly product, with obvious social and economic benefits.

If you are interested in building a micro hydropower power, please advise your available water source data for further discussions, such as Net Head (m), Design Flow (l/s), Required output Power (kW), Required Voltage(V), Frequency (50Hz or 60Hz), Off-Grid or On-Grid, etc as more details as possible.
