Thermal power plants generate electricity through a Rankine cycle where water is heated to steam to drive a steam turbine connected to an electrical generator. Key components include a boiler that heats water to steam, a steam turbine that converts the steam's energy to rotate the generator, a condenser that cools the steam back to water, and an alternator that converts the rotational energy to electricity. Air preheaters increase efficiency by transferring heat from flue gases to the air entering the boiler. Forced and induced draft fans control air and flue gas flow through the system.
A steam power plant generates electrical power through a process of converting the chemical energy in fossil fuels into mechanical energy that drives electric generators.

Solution
After studying the fundamental thermodynamic cycles of steam power plants and considering the
characteristics and thermochemistry of fuels, it is appropriate to consider the design of the
systems and flow processes that are operative in steam plants and other large-scale power
production facilities. This chapter will focus first on the processing of several fundamental
streams that play a major role in power plant operation. Up to this point, a great deal of attention
has been focused on the water path from the point of view of the thermodynamics of the steam
cycle. Additional aspects of the water path related to plant design are considered here. Another
fundamental flow in the power plant, the gas stream, includes the intake of combustion air, the
introduction of fuel to the air stream, the combustion process, combustion gas cooling in the
furnace heat exchange sections, and processing and delivery of the gas stream to the atmosphere
through a chimney or stack. A third important stream involves the transportation and preparation
of fuel up to the point that it becomes part of the combustion gas. A major non-physical aspect of
power production is the economics of power plant design and operation. This is considered in
conjunction with some preliminary design analyses of a prototype plant. Environmental
considerations also play an important part in planning and design. The chapter concludes with
back-of-the-envelope type calculations that define the magnitudes of the flows in a large plant
and identify major design aspects of steam power plants.
The Water Path
The Liquid-Water-to-Steam Path Several pumps are employed in the feedwater path of a steam
power plant to push the working fluid through its cycle by progressively elevating the pressure of
the water from the condenser to above the turbine throttle pressure. These pumps are usually
driven by electric motors powered by electricity .

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement.

3. THERMAL POWER STATION
• A Thermal Power Station is a power
plant in which the prime mover is steam
driven. Water is heated, turns into steam
and spins a Steam Turbine which drives
an electrical generator(Alternator). After
it passes through the turbine, the steam is
condensed in a Condenser; this is known
as a Rankine cycle.
5. Rankine Cycle
• There are four processes in the Rankine cycle, each changing
the state of the working fluid. These states are identified by
number in the diagram to the right.
• Process 1-2: The working fluid is pumped from low to high
pressure, as the fluid is a liquid at this stage the pump
requires little input energy.
• Process 2-3: The high pressure liquid enters a boiler where it
is heated at constant pressure by an external heat source to
become a dry saturated vapor.
• Process 3-4: The dry saturated vapor expands through a
turbine, generating power. This decreases the temperature
and pressure of the vapor, and some condensation may
occur.
• Process 4-1: The wet vapor then enters a condenser where it
is condensed at a constant pressure and temperature to
become a saturated liquid. The pressure and temperature of
the condenser is fixed by the temperature of the cooling coils
as the fluid is undergoing a phase-change.
6. What is a boiler?
• The steam generating Boiler is basically a
heat exchanger which has to produce
steam at the high purity, pressure and
temperature required for the steam turbine
that drives the electrical generator.
7. Boiler Parts
• The Boiler includes the Economizer, the steam
drum, the chemical dosing equipment, and the
furnace with its steam generating tubes and the
super heater coils. Necessary safety valves are
located at suitable points to avoid excessive
boiler pressure. The air and flue gas path
equipment include: forced draft (FD) fan, air
preheater (APH), boiler furnace, induced draft
(ID) fan, fly ash collectors (electrostatic
precipitator or baghouse) and the flue gas stack.
8. Air Pre-Heater (APH)
• APH is a heat exchanger in which air
temperature is raised by transferring
heat from other fluid such as flue
gases.
9. APH TYPES
1. Recuperative Type : Heating medium is on one side & air
is on the other side of tube /plate & heat transfer is by
conduction through the material which separates the
media.
2. Regenerative Type : Heating medium flows through a
closely packed rotating matrix to raise its temperature and
then air is passed through the matrix to take up the heat.
10. APH(TRISECTOR TYPE)
• Tri-sector types are the most common in modern power
generation facilities.In the tri-sector design, the largest sector
(usually spanning about half the cross-section of the casing) is
connected to the boiler hot gas outlet. The hot exhaust gas flows
over the central element, transferring some of its heat to the
element, and is then ducted away for further treatment in dust
collectors and other equipment before being expelled from the
flue gas stack. The second, smaller sector, is fed with ambient air
by a fan, which passes over the heated element as it rotates into
the sector, and is heated before being carried to the boiler
furnace for combustion. The third sector is the smallest one and
it heats air which is routed into the pulverizers and used to carry
the coal-air mixture to coal boiler burners. Thus, the total air
heated in the RAPH provides: heating air to remove the moisture
from the pulverised coal dust, carrier air for transporting the
pulverised coal to the boiler burners and the primary air for
combustion.
11. Boiler Draft Control
• Induced draft: This is obtained one of three ways, the first being the
"stack effect" of a heated chimney, in which the flue gas is less dense than
the ambient air surrounding the boiler. The denser column of ambient air
forces combustion air into and through the boiler. The second method is
through use of a steam jet. The steam jet oriented in the direction of flue
gas flow induces flue gasses into the stack and allows for a greater flue gas
velocity increasing the overall draft in the furnace. This method was
common on steam driven locomotives which could not have tall chimneys.
The third method is by simply using an induced draft fan (ID fan) which
removes flue gases from the furnace and forces the exhaust gas up the
stack. Almost all induced draft furnaces operate with a slightly negative
pressure.
• Forced draft: Draft is obtained by forcing air into the furnace by means
of a fan (FD fan) and ductwork. Air is often passed through an air heater;
which, as the name suggests, heats the air going into the furnace in order to
increase the overall efficiency of the boiler. Dampers are used to control the
quantity of air admitted to the furnace. Forced draft furnaces usually have a
positive pressure.
• Balanced draft: Balanced draft is obtained through use of both
induced and forced draft. This is more common with larger boilers where the
flue gases have to travel a long distance through many boiler passes. The
induced draft fan works in conjunction with the forced draft fan allowing the
furnace pressure to be maintained slightly below atmospheric
12. ESP
• An electrostatic precipitator is a large, industrial emission-control
unit. It is designed to trap and remove dust particles from the
exhaust gas stream of an industrial process.
13. Steam turbine
• A steam turbine is a mechanical device
that extracts thermal energy from
pressurized steam, and converts it into
rotary motion.
• Because the turbine generates rotary
motion, it is particularly suited to be used
to drive an electrical generator – about
80% of all electricity generation in the
world is by use of steam turbines.
15. Principle of Operation
• An ideal steam turbine is considered to be an isentropic
process, or constant entropy process, in which the
entropy of the steam entering the turbine is equal to the
entropy of the steam leaving the turbine. No steam
turbine is truly “isentropic”, however, with typical
isentropic efficiencies ranging from 20%-90% based on
the application of the turbine. The interior of a turbine
comprises several sets of blades, or “buckets” as they
are more commonly referred to. One set of stationary
blades is connected to the casing and one set of rotating
blades is connected to the shaft. The sets intermesh with
certain minimum clearances, with the size and
configuration of sets varying to efficiently exploit the
expansion of steam at each stage .
16. Impulse Turbines
– An impulse turbine has fixed nozzles that orient the steam flow
into high speed jets. These jets contain significant kinetic energy,
which the rotor blades, shaped like buckets, convert into shaft
rotation as the steam jet changes direction. A pressure drop
occurs across only the stationary blades, with a net increase in
steam velocity across the stage.
– As the steam flows through the nozzle its pressure falls from
steam chest pressure to condenser pressure (or atmosphere
pressure). Due to this relatively higher ratio of expansion of
steam in the nozzle the steam leaves the nozzle with a very high
velocity. The steam leaving the moving blades is a large portion
of the maximum velocity of the steam when leaving the nozzle.
The loss of energy due to this higher exit velocity is commonly
called the "carry over velocity" or "leaving loss".
17. Reaction Turbines
– In the reaction turbine, the rotor blades themselves
are arranged to form convergent nozzles. This type of
turbine makes use of the reaction force produced as
the steam accelerates through the nozzles formed by
the rotor. Steam is directed onto the rotor by the fixed
vanes of the stator. It leaves the stator as a jet that
fills the entire circumference of the rotor. The steam
then changes direction and increases its speed
relative to the speed of the blades. A pressure drop
occurs across both the stator and the rotor, with
steam accelerating through the stator and
decelerating through the rotor, with no net change in
steam velocity across the stage but with a decrease
in both pressure and temperature, reflecting the work
performed in the driving of the rotor.
18. Steam Condenser
• Surface condenser is the commonly used term for a
water cooled shell and tube heat exchanger installed on
the exhaust steam from a steam turbine in thermal
power stations. These condensers are heat exchangers
which convert steam from its gaseous to its liquid state
at a pressure below atmospheric pressure. Where
cooling water is in short supply, an air-cooled condenser
is often used. An air-cooled condenser is however
significantly more expensive and cannot achieve as low
a steam turbine exhaust pressure as a surface
condenser
19. Alternator
• An alternator is an electromechanical device that
converts mechanical energy to alternating current
electrical energy. Most alternators use a rotating
magnetic field but linear alternators are occasionally
used. In principle, any AC electrical generator can be
called an alternator, but usually the word refers to small
rotating machines driven by automotive and other
internal combustion engines
20. Principle of operation
• Alternators generate electricity by the same principle as DC generators,
namely, when the magnetic field around a conductor changes, a current is
induced in the conductor. Typically, a rotating magnet called the rotor turns
within a stationary set of conductors wound in coils on an iron core, called
the stator. The field cuts across the conductors, generating an electrical
current, as the mechanical input causes the rotor to turn.
• The rotating magnetic field induces an AC voltage in the stator windings.
Often there are three sets of stator windings, physically offset so that the
rotating magnetic field produces three phase currents, displaced by one-
third of a period with respect to each other.
• The rotor magnetic field may be produced by induction (in a "brushless"
alternator), by permanent magnets (in very small machines), or by a rotor
winding energized with direct current through slip rings and brushes. The
rotor magnetic field may even be provided by stationary field winding, with
moving poles in the rotor. Automotive alternators invariably use a rotor
winding, which allows control of the alternator generated voltage by varying
the current in the rotor field winding. Permanent magnet machines avoid the
loss due to magnetizing current in the rotor, but are restricted in size, owing
to the cost of the magnet material. Since the permanent magnet field is
constant, the terminal voltage varies directly with the speed of the
generator. Brushless AC generators are usually larger machines than those
used in automotive applications.and the large alternators in power station
which are driven by steam turbine are called turbo alternators
21. Poles verses RPM
• The output frequency of an
alternator depends on the
number of poles and the
rotational speed. The speed
corresponding to a particular
frequency is called the
synchronous speed for that
frequency. This table gives
some examples:
Poles RPM at
50Hz
2 3000
4 1500
6 1000
8 750
10 600
12 500
14 428.6
16 375
18 333.3
20 300
