The document discusses hydroelectric power plants. It describes how hydroelectric plants harness the kinetic and potential energy of flowing water to generate electricity. The key components of a hydroelectric plant include a reservoir for water storage, a dam, penstocks to carry water to the turbines, and a powerhouse containing the turbines and generators. Hydroelectric plants convert the energy of falling or flowing water into rotational energy to drive the generators and produce electric power.
Flow in super critical state is an unstable type of flow. It has a tendency to transfer n to sub critical flow. Flow depth is small in a supercritical state. which increases suddenly while changing the subcritical state. This phenomenon sudden increase in depth of flow is called a HYDRAULIC JUMP.

• Hydroelectric power (often called hydropower) is considered a renewable energy source. A renewable energy source is one that is not depleted (used up) in the production of energy. Through hydropower, the energy in falling water is converted into electricity without “using up” the water. Hydroelectric power (hydropower) systems convert the kinetic energy in flowing water into electric energy.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. Hydro-Electric Power Plant
• The purpose of a hydro-electric plant is to harness
power from water flowing under pressure
• Water flowing under pressure has two forms of
energy:
– Kinetic and,
– Potential
• The kinetic energy depends on the mass of water
flowing and its velocity
• The potential energy exists as a result of the
difference in water level between two points which
is known as ‘head’
3. Hydro-Electric Power Plant
• The water or hydraulic turbine, as it is sometimes
named, converts the kinetic and potential energies
possessed by water into mechanical power
• The hydraulic turbine, is thus, a prime mover
which when coupled to a generator produces
electric power
• The project design to produce electric power from
water are known as hydro-electric projects
• Single purpose projects (power generation) and
multipurpose projects (irrigation, floods etc..)
4. Hydro-Electric Power Plant

• Generation and transmission of electric power
9. Reservoir
• A reservoir is employed to store water available form
catchment area which is further utilized to generate
power by running the hydraulic turbines
• Two types: Natural and Artificial
• An artificial reservoir is built by erecting a dam across
the river
• Water held in upstream reservoir is called storage
whereas water behind the dam at the plant is called
poundage
10. Dam with its Control Works
• Dam is a barrier to confine or raise water for storage or
diversion to create a hydraulic head
• An hydro-electric dam diverts the flow from the river to
the turbines and usually increases the head
• A reservoir dam stores water by raising its level
• Dams are built of concrete or stone masonry, earth or
rock fill, or timber
• A barrage is a diversion dam, especially at a tidal power
project
• A weir is a low overflow dam across a stream for
measuring flow or maintain water level, as at a lake
outlet
12. • Earth Dam
– An earth dam is made of earth (or soil) built up by
compacting successive layers of earth, using the most
impervious materials to form a core and placing more
permeable substances on the upstream and downstream
sides
– Earth dam resists the forces exerted upon it mainly due to
shear strength of the soil
Canyon Dam, an
earthen dam
13. • Rock - fill Dam
– A rock fill dam is built of rock fragments and boulders of
large size
– An impervious membrane is placed on the rock fill on the
upstream side to reduce the seepage through the dam
14. • Gravity Dam
– A gravity dam is a massive sized dam fabricated from
concrete or stone masonry
– The weight of the dam is actually able to resist the
horizontal thrust of water pushing against it
– Gravity essentially holds the dam down to the ground,
stopping water from toppling it over
Grand coulee Dam,
Washington, USA, a
solid gravity dam
15. • Buttress Dam
– It has a watertight upstream side supported by triangular
shaped walls called buttresses
16. • Arc Dam
– An arch dam is curved in plan, with its convexity towards
the upstream side
– An arch dam transfers the water pressure and other forces
mainly to the abutments by arch action

• Butterfly Valves
– Butterfly valve normally applied in front of the low and
medium head water turbine with head range up to 200m
– Mainly consist of a ring shaped housing, the valve disc,
operating mechanism and counter weight
25. Dam Contd..
• Devices for protection of gates and hydraulic machines
– Trashracks
• They are made up of a row of rectangular cross sectional structural steel bars
placed across the entire intake opening in an inclined position.
• They are used to obstruct debris from going into the intake
– Debris cleaning device fitted to the trash rack
– Heating element against ice troubles
26. Waterways with their Control Works
• Waterway is the passage through which the water is carried
from the storage reservoir to the power house
• It may consist of
– Tunnels
– Canals
– Flumes
– Forebays
– Pipes (Penstock)
27. • Tunnel
– Tunnel is the passage made by cutting mountain to save distance
– In high head power plants it is normally called head race tunnel which
connects the water intake and the pressure shaft
– At the end of the head race tunnel there is a sand trap
– Beside the sump in the tunnel floor the cross section of the tunnel is
gradually increased to reduce the water velocity and allow for a better
sedimentation of suspended particles
28. • Canals
– They serve the same purpose as the tunnels
– Open canals are usually digged in the ground, blasted in
rock or built up as a chute of wood or concrete
29. • Forebay
– It is an enlarged section of a canal spread out to
accommodate the required width of intake
– Its function is to store temporarily, the water rejected by
the plant when its load is reduced and to meet the
instantaneous increased demand of water due to sudden
increase in load
– Usually found in case of medium and low head power
plants where the length of penstock is short
30. • Penstocks
– They are pipes of large diameter carrying water under
pressure from the storage reservoir to the turbine
32. • Surge Tank
– It is a storage reservoir fitted at some opening made on a
long penstock to receive the rejected flow when the
penstock is suddenly closed by a valve fitted at its steep
end
– Functions of surge tank
• Control of pressure variations resulting from rapid
changes of flow in penstock, relieving the line of
excessive pressure, thus eliminating water hammer
effects
• Regulation of flow in power plants by providing
necessary acceleration and retarding head
• Regulation of turbine speed
33.
34. • Power house is a building to house the turbines, generators
and other accessories for operating the machines
• Tail Race is a waterway to conduct the water discharged from
the turbines to a suitable point where it can be safely
disposed of or stored to be pumped back into the original
reservoir
