MICRO HYDRO
 
How Do Micro Hydro Systems Work?
Hydro power is an olde stablished method of energy production.
 
 
 
Water is captured via a filter
/ intake structure and passes
downhill in a pipeline to the
turbine. The water exits the
pipe under pressure through
a nozzle and strikes a water
wheel (runner). The force of
which spins the runner
which is direct coupled to an
electricity generating
permanent magnet alternator
or enhanced performance
induction generator. The
electricity is then
electronically regulated and
transmitted via cable for use.
 
 
How much energy can be produced?
This depends on the water pressure and volume available. Pressure is measured in terms of "head". Head is the vertical
distance, in meters, from the water take-off point to the turbine. The volume is measured as "flow" in litres per second. Once accurate head and flow figures are available potential energy can be calculated. Accurate site evaluations and system design are
just some of the services available to you.
 
 
How much of the creek flow should be used?
Generally speaking less than 50% of the flow at the driest time of year.
This will allow water for the fish, other creatures and the environment.
 
The greatest fall over the shortest route. It is easier and cheaper to transmit electricity than to pipe water.
A micro hydro can be situated up to 2km from the facility it is supplying. However when systems are
designed this distance is kept as short as possible.
 
A permanent water supply is needed and a turbine site that is above high water. Also look at the terrain, to choose the best
route and method of running the pipe.
 
The higher the flow that is available the less head is needed to produce a given amount of power, and vice versa. See performance specs.
 
Does Micro Hydro offer value for money?
Micro hydro is the most cost-effective way of generating electricity where there is a reliable supply of water.
Maintenance is minimal and there are no fuel costs. Electricity is generated 24 hours a day, 7 days a week.
 
The average hydro electric generator costs only one-tenth as much as a solar system of equivalent output.
 
How much power do we need?
This is an individual question. A load analysis will determine this. The "typical" household requires between 250 to
350 watts continuous from a DC system or 1500 watt from a direct 110/240 volt AC system.
 
This will run all appliances and lights in an average household, including a fridge and washing machine. Stoves and hot water
are usually powered by gas, wood or solar hot water systems, unless more electricity is available.
 
Hydro equipment is designed to run continuously for years before maintenance is required. Attention to detail during
installation of the pipeline, turbine and axillary equipment are key area to ensure reliability along with proper water filtering.

TURGO IMPULSE WHEEL
 
The Turgo wheel is basically an improved version of the Pelton. It was
designed by Eric Crewdson in 1920. The maximum efficiency of an
impulse wheel is achieved when the velocity of the runners at the center
line of the nozzle is half the velocity of the incoming water. To achieve
the highest velocities the ratio of the diameter of the wheel and the
diameter to the center of the nozzle should be as small as possible..
The wheel has a minimum ratio of 9:1, the Turgo has a minimum ratio
of 4:1. The Turgo is half the size of the Pelton and operates at twice the
speed. This makes the unit cheaper and reduces the amount of gearing
necessary. The Turgo has an efficiency of over 80% and runs on head
of 40 feet or more.
