MICRO HYDRO-ELECTRICITY PROJECT KADUGANNAWA.

According to the vision and concept of

Mr Dhammika Bede Cooray

The Founder and Chairman of Vinseth Group Of Companies and the Guidance of

Mr Sarath Vijayananda & Mr. Nihal Weerawarna

Directors of Vinseth Group of Companies,

This Micro Hydro Power Plant Established by the Engineering Division of Vinseth Group was declared open by

Mr Barana Ranaweera – Technical Director Vinseth Group/Senior Engineer –Intel USA/President SHS Solar USA

30th July 2010

ABOUT SITE Site located 120Km East of Colombo –Sri Lanka, in one of the most scenic areas in the hills of Sabaragamuwa. Namely Gadadessa Estate. (50Arcres)

Project Target Power up 2 Houses with Street Lights. 230V AC SYSTEM 24Volts DC Invert to 230V AC

PROJECT VISION Generate Hydro- Electricity, Keeping Eco-Friendly Environment.

After a couple months of concentrated work we have a fully functional micro-hydropower plant at Gadadessa Estate. The project uses a completely new technology. Used Micro Hydro Stream Engine, Charge Controller, DC Panel Board, Battery Bank, DC AC Inverter System, AC Panel and assess power unit too. In the Estate (2 Houses) we’re getting 220-230Volts out put at around 50 Hz. While we found we could generate up to 15A /28V DC for battery Charge. We’ve throttled it back to about

2-5A/28V DC to keep more water in the pool.

ITEM DESCRIPTION. 1. Stream Machine – Energy System & Design Ltd – Canada

The Stream Engine employs a brush less, permanent magnet alternator which is adjustable, enabling the user to match turbine output to the electrical load. It has higher efficiency than previous alternators, and is capable of outputs over 1 kilowatt (kW).

2. Charge Controller – Morningstar

3. DC Panel – Ampere Meter/Volt Meter

4. Battery Bank –12V 100Ah X 2 –Series Combination

5. Assess Power 190 W X 2 24 V Lights

6. Inverter Breaker

7. DC-AC Inverter – 24V DC to 500W 230V AC 1st we used Imported inverter. But due to high humidity/Condense that inverter burnt out. So I design and made this Humidity protected inverter.

8. AC Panel

9. 4’’ PVC Pipe 35 Nos , Valves & Pressure Gauge

10. Wires /Lugs /Conduits/casing Horse and other fixing accessories

Experimental Level After the lot of site experiments we found ideal place for build up Power Room. Considered Following Things 1. Water Pressure 2. Length of Electricity Line to Houses 3. Pipe line Bends 4. Length of Pipe Line /Diameter/Strength The photos below tell the story better than words!
