Aim
In
order
to
deal
with
commuters
to
have
reliable
mobile
telecommunication networks that they
across the
railway, We
need
wind
power
.solar
power
and
water
power
to
design
hybrid renewable power
systems.
Introduce
According to research. We need wind.
and equipment are
1KW Wind Turbine
Generator Controller
Tower mounting
solar:
equipment
includes
high
quality
solar
modules
with
25
year warranty. And solar module
mounting frames in addition
LCD display
with data logging maximum power point tracking
solar booster solar module tracking
frames.
Scope
Depending on the new railway lines, And
the hybrid renewable
power systems
lives near here.
The problem
Difficult to control the climate and
exhaust noise.
Conventional
hydro requires the flooding of lacking large areas
of land, and battery cost and inverter
cost.
According
to
research,
we
can
learn
that
Remote
districts
use electricity
the load not to be all big generally, therefore is
uneconomical with the electrical
network power transmission,
directly
generates
electricity
commonly
used
in
the
locality
uses
the diesel electric engine. But the diesel oil
storage and
transport too is high to
the remote districts cost, therefore the
diesel
electric
engine
only
can
take
one
kind
of
short-time
emergency
power
supply,
Must
solve
the
long-
term
stability
reliable
power
supply
problem,
only
can
rely
on
local
the
natural energy source.
The solar energy gentle breeze can be
most
universal
and
the
water
power,
Solar power
Accord
to
solar
data,
we
use
solar
power
in
summer
from
eleven
o’clock
to
fourteen
every
day
and
winter
time
is
from
eleven o’clock to thirteen
In order to good use of wind power, We
learn that sometimes the
wind speed is
the highest in Autumn, on the contrary, the wind
have the least spring
The water system transmits power from
the turbine shaft to the
generator shaft or the shaft powering
another device, and as the
voltage is
very high wiring can be kept to a minimum and the
wiring can be run over a longer
distance due to the higher
voltage
4.1
Output Requirements for the
Power System
The maximum total energy
requirements by the telecommunication transmitter
site is
1kWhr /
day.
Typically
most telecommunictions infrastructure works on
48VDC
The maximum
current for thie output equipment would be under
10 Amps
The design will incorporate storage of
energy for 3 days in the case for lack of
generation from all of the inputs

4.1.2 Battery storage size
required
To calculate the
size of the battery bank required we converted the
toatal daily
energy consumption in
Watt-hours to Amp-hours.

Then multiply this by the required
number of days storage plus one additional

For this location we factor
