Introduction
One of the major and most inevitable forms of energy for the
modern human race is Electricity. Its absence is enough to put the
existence of several socioeconomic infrastructures to question. It is easy
to handle, simple to transport and is very versatile. Tis trait makes it the
most desirable source of energy. Tere are various ways of generation
of Electricity, namely, Termal, Hydro, Geothermal, Nuclear and many
more. Here, we will be discussing about the Steam Power Plants, which
can be classifed under Termal.
Steam power plants play a key role in electric power generation.
Terefore the Rankine steam power cycle is one of the most important
cyclic processes used in industry. Te efciency is up to 45% with recent
technological advancements [1-3].
Working Principle of a Steam Power Plant
Te working fuid is Water. Te advantage of this type of power
plant is. It uses the same fuid repeatedly. Firstly, the water is fed into
the boiler, where it is heated and eventually turns to vapor phase. Tis
steam produced by the boiler is directed to do work on the turbine to
produce mechanical power in the form of rotation.
Te steam from the turbine is then fowed into the condenser to
be cooled with the cooling water. At this stage, the steam is back to its
liquid stage.
Te rotation of turbine is used to turn a generator that is coupled
directly to the turbine. So, when the turbine rotates, the generator
output terminals generate electricity. Tough, the working fuid (water)
works in a closed cycle, there will be some decrease in its volume.
Tis is due to leakages, either intentional or unintentional. Te
efciency of the plant working on steam is a function of the maximum
temperature of the steam generated and is not directly proportional to
the fuel used. Tus, the type of fuel used is insignifcant as regards to the
efciency of the steam power generation, but plays an important role in
the overall system efciency (Figure 1).

Abstract
As the world is getting more and more sensitive towards the use of energy, it is moving their focus towards
independent and distributed ways of generation of energy. Distributed Generation (DG) based on Renewable Energy
Technologies (solar, wind, hydro and biomass) is becoming a more important energy option in the future generation
system. What we are trying to implement is breaking the large central power plant into multiple smaller, non-centralized
power plants. In this way, each user can generate the appropriate amount of power they need and subsequently result
in an effcient usage. We will be distributing a centralized energy generation point into a network on smaller energy
generation points we will call this network as a “grid”. We will also be simulating our idea to verify our claim. In the
longer-term, a system-wide approach for determining Distributed Generation costs and benefts should be adopted.
Arduino
For operation control using Servo Motor.
MCC DAQ card
Used for monitoring process parameters.
Using the results obtained from real time simulations, we have
concluded that our proposal of distributed power generation is
applicable, both from the technological and economical point of view.
Process Measurement and Simulation Details
We will be using the DAQ MCC 1208FS card for monitoring our
steam power plant, we provide the required control using an Arduino
Board and the sofware used is NI Lab View.
MCC expands to Measurement Computing Corporation. DAQ
expands to Data Acquisition. Te mission of Measurement Computing
Corporation is to provide our customers with PC-based data acquisition
hardware and sofware that will save time and save money [4].
A steam power plant will have a number of sensors, like,
Temperature sensor, Pressure sensor, Flow sensor, Level sensor, RPM
sensor, PH sensor, Vibration sensor, Voltage sensor [5].
Temperature monitoring of the boiler
Termocouple is used to monitor the boiler temperature. Te
output of the sensor is obtained in milivolts (mV). In our simulation
process, the boiler is heated to 100 degrees centigrade, afer that the
water is allowed to become steam. Te positive terminal of the sensor
is connected to Channel-0/Ai0 IN, Pin 1 and negative terminal is
