The document describes a town park management system that uses renewable energy sources to automate operations. It details how solar panels, piezoelectric sensors, and a seesaw with a dynamo are used to generate and store electricity in a battery. This stored energy is then used to power the water pump, gate motor, lights, and alarm buzzer according to a schedule controlled by an LED clock. The system opens the gate and turns on water and lights before visitors arrive, sounds an alarm before closing, and leaves one light on overnight using an LDR sensor. Recommendations include adding more renewable sources, piezoelectrics, and an LCD display for the clock.

Energy is given in MU and peak is given in MW
Surplus-it occurs when the demand
exceeds of its supply.
Deficits-gave between supply and
demand. It occurs when demand
exceed supply
Every year not completed the
target of power generation.
Less power generation than
demand.
As seen from above table
huge difference between peak
demand and peak meat.

3. The Asian Development Bank (ADB) recently released an excellent report
on Myanmar’s energy sector. In the above table in it they presented
estimates of future demand growth by the Ministry of Electric Power for
electricity.
Show demand doubling from 12,459
million kWh in 2012-13 to 25,683 million
kWh in 2018-19, a compound rate of
growth of 13% a year.
the actual production in 2012 appears to be only
10,000 million kWh, and it is unlikely that
moving to 2012-13 will raise the total much
beyond 10,500 million kWh. Of this output,
about 1700 million kWh will be exported.
Electricity exports exceeded 1700 million kWh
in both 2010 and 2011.
electricity output in 2012-13 available for
domestic use will be 3659 kWh below this
year’s demand estimate. Production for
domestic use would have to jump by 42% to
equal the expected demand

4. Maharashtra is the largest power generating state in
India with installed electricity generation capacity of
26,838 MW (As on 31st August 2012). Maharashtra
constitutes 13% of the total installed electricity
generation capacity in India
Maharashtra experienced increasing capacity addition
in the last few years. In the year 2005, Maharashtra
had total installed capacity of around 10,223 MW. The
capacity has been increased to 26,538 MW in the year
2012
The peak demand deficit in the state has increased from 17% in 2005-06 to 22% in 2011-12.
Between 2005-06 and 2011-12, peak electricity demand grew at a compound annual growth
rate (CAGR) of 5%, while peak demand met at the CAGR of 4% over the period of 8 years.
Peak Demand/Peak Met in the state of Maharashtra

5. Actual Power Supply Position Of the state in Maharashtra
Electricity deficit in the
state has increased from
12% in 2005-06 to 17%
in 2011-12. Between
2005-06 and 2011-12,
electricity requirement
grew at a compound
annual growth rate
(CAGR) of 6%, while
availability only grew at
around 5% leading to
increasing electricity
deficits.

6. SOLUTION OF PROBLEM
Renewable energy sources are important because
when used they contribute little or no pollution to the
atmosphere. Renewables are real alternatives to
conventional forms of energy.
May play an important role in future efforts to
reduce energy-related emissions. They also have
relatively low operating costs compared to
conventional sources
It can be roughly estimated that replacing all of
our fossil fuel power plants with solar power
plants that last for 30 years and deliver three
times the energy it took to construct and install
them over that period will require the total
amount of electricity that we currently generate
in an entire decade

8. PIEZOELECTRIC SENSOR
The working principle is simple. When a
pedestrian steps on the top plate of the device,
the plate will dip down slightly due to the weight
of the pedestrian. The downward movement of
the plate results a mechanical stress to produce
electrical energy. The top plate reverts back to its
original position due to its flexibility. This
electrical energy is stored in the battery.
SOLAR PANEL
Solar-powered photovoltaic
(PV) panels convert the sun's rays
into electricity by exciting electrons
in silicon cells using the photons of
light from the sun Solar panel
converts the solar rays into electrical
energy which gets stored into the
battery which further uses to supply
current to the circuit.
RIDES (SEE-SAW)
A dynamo is attached
with this see-saw
whose shaft is
rotated with this to
produce electrical
energy and that can
also store in the
battery

9. WATER SUPPLY
Automatically water supply before
opening of park for visitor. The water
supply through dc water pump. Water
supply for the purpose of irrigation.
GATE
The gate is opened by running the
motor which is driven by a motor
driver. Open and close the door by
running the motor whenever need to
open and close the door.
AUTOMATIC LIGHT
The lights are switched
on depending upon the
output of the LDR and
the lights remain
functional till the garden
remains open for visitors.
Before park closed for
visitor.
ALARM ALERT
Before park closed for
visitor. A buzzer is
sounded to indicate
closure of the garden and
alert the visitors.
LED CLOCK
LED clock is used to supervise
the actions of all other devices
and to control the entire set of
operations.

10. • DESCRIPTION OF THE TOWN PARK MANAGEMENT SYSTEM
• Firstly, the electronic system 4.00pm switches on the water supply once to water the
entire garden few hours before opening of the garden for public. Next the gate is
opened by running the motor which is driven by a motor driver. At 6.00pm the lights
are switched on depending upon the output of the LDR and the lights remain
functional till the garden remains open for visitors.
• The garden remains open for about three hours and so at 9:00 pm a buzzer is
sounded to indicate closure of the garden and alert the visitors. The gate is then
closed at 10pm and one of the two lamps is switched off. One lamp is kept on
throughout the night. In the morning the remaining lamp is switched off depending
upon the signal sent by the LDR, light dependent resistor to the electronic circuit.
These are the step involved in the operation of the circuit and the public garden
automation. LED clock is used to supervise the actions of all other devices and to
control the entire set of operations.
• All these settings can apply using this clock. Settings can also easily changed by
park authorities.

13. • Number of solar panel can be increased to generate more power.
• More and more number of piezoelectric putted on the gate of park for maximum
efficiency.
• With LED clock and also may be LCD interfacing for digital clock.
• Make the solar panel should be moveable. As sun moves then solar panel also has
to move in the direction of sun.
• All the light should be automated. As intensity of light increases light should be
off and intensity of light decrease then light should be on.
