Microhydropower can be one of the most simple and consistent forms or renewable energy on your property.
If you have water flowing through your property, you might consider building a small hydropower system to generate electricity. Microhydropower systems usually generate up to 100 kilowatts of electricity. Most of the hydropower systems used by homeowners and small business owners, including farmers and ranchers, would qualify as microhydropower systems. But a 10-kilowatt microhydropower system generally can provide enough power for a large home, a small resort, or a hobby farm.
A microhydropower system needs a turbine, pump, or waterwheel to transform the energy of flowing water into rotational energy, which is converted into electricity.
This kind of Micro-hydro Generator is consisted of an
inclined impulse turbine and a set of direct connected AC single-phase /
three-phase generator. With the characteristics of small body, lightweight,
simple structure, reliable operation and convenient assembly, and serving
as the power source of lighting, TVs and recorders, it is most suitable for
the households in mountain areas with scattered and small hydroelectric
sources. The consumers can do easily themselves the installation and
operation. This product has been thoroughly strengthened in the special
technical measures to good quality, stable function and easy operation for
women and children. Much less investment may add more happiness to your
family.

The typical micro hydro generator
station is as follows (figure 1),which consists of earthwork(inlet conduit
construction,unit room and drain etc),the micro hydro generator,electrical
wires and the users wires.

The work process is as follows:Collecting the water
of stream by reservior,the water inflow the pressure poor through the inlet
conduit,the go into th micro hydro generator which is installed in the unit
room through the inlet pipeline,force the runner to circumgyate,which
drives the genertator to generate electricity.At eh same time,the
adjustment machine autoadjust the voltage and the frequency to meet the
requirements for power supply,and then the user can use the electricity
transmitted hyelectrical wires.
Operation Method:
1) Firstly, check whether all
components are completed and the intake of penstock is blocked.
2) Then check whether the runner
of turbine can be easily rotated, and rotated in by hand to ensure the
voltage meter has readings (put the output switch in OFF position).
3) For the first starting, the
output switch should be put in the voltage-stabilized control position (A),
then open the gate to let water out from small to large, observe the
readings meter till 230V (380V) or so continue enhancing water volume, the
voltage device is reliable if the reading keep still. At this time the load
can be connected, then adjust the water volume to hold the output of 230V
(380V) or so. Once the stabilizing device break down, put the switch in B,
then the voltage of unit will be under manual-controlled, you may follow
the next procedure to control by valve.
4) During the
operation, the load should be kept stable as possible as can be. Don't shut
off the load suddenly, or else the high voltage will burn out the rest
load, if you must is connect the load, you may decrease water to small
volume at first, then disconnect the most part of load when the voltage has
dropped to below 380v (you must do as this even you run the unit under the
using of voltage-stabilizing device).
5) It need only close the valve to
switch off the unit when the load has been stable after first operation,
the power switch may hold on so that you may adjust voltage up to 230V
(380V) directly for next running.
Maintenance:
1) To check and clean
the mud and foreign material blocking in the intake house and trash rack.
2) The frame of
unit should be injected water-proof grease by using grease cup in every
three month, each time rotating for three times. The upper bearing also
should be added waterproof grease for every six months.
3) The generator must be conducted the
dry treatment before next start if it became wet.
