Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems.

urban population more than doubling its current size by 2050 (70% of total
population).
4. Need for Mass Rapid Transport (MRT) System
There is no universal definition of what constitutes an ‘urban area’; definition vary widely across
countries, both in terms of the metrics used to define them, and their threshold level.
The data of shown for a given country in the map on previous slide is its nationally-defined minimum
threshold. 2000 and 5000 inhabitants are the most frequently used threshold level (by 23 countries
each). However, these ranges vary widely. 133 countries do not use a minimum settlement
population threshold in their ‘urban’ definition. Some use a variation of population density,
infrastructure development, or in some cases no clear definition.
5. Need for Mass Rapid Transport (MRT) System
By 2030, the world is projected to have 43 megacities with more than 10 million
inhabitants, most of them in developing regions. However, some of the fastest-growing
urban agglomerations are cities with fewer than 1 million inhabitants, many of them
located in Asia and Africa.
However, the speed and scale of urbanization brings challenges, such as meeting
accelerated demand for affordable housing, viable infrastructure including transport
systems, basic services, and jobs.
6. Need for Mass Rapid Transit (MRT) System
The percentage of Urban population in India is reported at 35.87 % in 2022
and it is expected to be more than 50 % by 2050.
Due to urbanization, Indian cities are growing rapidly and witnessing fast
growth in the number of personal motor vehicles causing severe strain on
existing road transport infrastructure.
This is resulting in severe road traffic congestion and air pollution.
Hence, more & more cities are experiencing need for Mass Rapid Transit
(MRT) system to meet their ever increasing demand of public transport &
mobility requirement.
Metro rail, which provides high capacity public transit, has seen substantial
growth in India in recent years.

based on a single rail, which acts as its sole support
and its guide-way.
Each train consists of either four or six cars with
a capacity to accommodate 568 passengers (4 cars) &
852 passenger (6 cars) at a time.
A 4-coach monorail train has a total length of 44.8
metres and each coach weighs 15 tonnes.
Maximum Operational speed: 80 Kmph.
16. Skybus Metro System

width & 3.9 m height and 16 t axle load). Passenger
carrying capacity of a train set of 3 coaches: 764 (at 6
standee/sq.m) & 972 (at 8 standee/sq.m)
Maximum operational speed: 80 Kmph.
21. Major difference in construction of Metro rail and
normal Railway line
Metro lines are mostly constructed in congested urban areas.
Since metro line is constructed in urban areas, major challenges in its
construction are:
(1) Constraints in construction due to limited working space (in congested
urban area), limited working hours for transportation of materials to & from
site (during night time only) and for actual construction activities (during
day time only).
(2) Dealing with large number of sub-surface, surface and overhead public
utility services, viz. sewers, water mains, storm water drains, gas pipe lines,
telephone cables, electrical transmission lines, electric poles, traffic signals
etc. falling in metro alignment:- Either redesign of metro structures or
shifting utility/supporting & maintaining them during construction.
(3) Regulation of vehicular traffic during construction.
23. Civil Engineering Structures in Metro rail
From construction point of view, metro Civil Engineering
Structures can be broadly classified in to:
(A) Elevated
(i) Viaduct
(ii) Station
(B) Underground
(i) Tunnel
(ii) Station
(C) Maintenance depot
27. Construction of Pile foundation
• Generally, in metro rail construction bored cast in situ R.C.C. pile
foundation of 0.8 m, 1.00 m & 1.20 m diameter with varying depth (22 m.
to 32 m.), depending upon foundation soil properties, are used.
31. Construction of Piers
• Metro piers are generally cast-in-situ Reinforced Cement Concrete
(RCC) structure. They are generally circular, oblong, square or
rectangular in shape.
32. Types of metro pier
• Normal (concentric) pier, Cantilever pier or Portal pier

34. Construction of Pier cap and Pier arm
• Pier cap is either cast-in-situ RCC or precast post tensioned Prestressed
Concrete (PSC) structure. But now, mostly precast post tensioned
Prestressed Concrete (PSC) is used for both pier cap (viaduct) and pier arm
(stations).
Cast-in-situ Pier cap construction
37. Bearings
• A bridge bearing is an element of superstructure which provides an interface between the
superstructure and substructure.
• Bearing performs the function of
(1) allowing translation and rotational movement of superstructure to occur and
(2) transfers the entire load from superstructure to the substructure of bridge.
• Types of bearings in Metro rail:
1. Elastomeric bearing: An Elastomer is a polymeric substance obtained by vulcanization of rubber.
Elastomeric bearing consists of elastomer layers with 1 mm to 3 mm thick steel plates between the
elastomer layers bonding firmly with the elastomer. Used for bridge span up to 45.7 m.
38. Bearings (Contd.)
2. POT-PTFE bearing: Used for relatively larger span/heavier load. PTFE (Poly Tetra Fluoro
Ethylene), also known as Teflon, is a hard & durable material and it possesses high
chemical resistance. The elastomer pad inside the POT provides rotational movement by
differential compression of elastomer. The translation movement to superstructure is movement
is provided by steel plate sliding over PTFE. The coefficient of friction between PTFE and stainless
steel is the lowest between any two materials within the normal temperature range.
39.
40. Bearings (Contd.)
3. Spherical Bearing: It consists of a set of concave & convex
steel backing plate with a low friction sliding interface (PTFE) in
between
(i) permits rotation by incurve sliding,
(ii) for providing sliding movement, the bearings may be combined
with flat sliding elements, guides and restraining rings.
Spherical bearing is provided in Metro railway bridges with spans
of 61 m. or more or in open web through girders where high
rotational & sliding movement are needed and the vertical
load transmitted through each bearing is too large.
43. Girder or Truss
• Different types of girders and Truss used in metro are:
1. Segmental precast pre-stressed Concrete (PSC) box girder: Number of precast PSC
box segments each of 2.5 m. to 3.0 m length are post tensioned at site. Used for
spans of 22 m. to 37 m. and up to sharpest curve of 140 m. radius. Precast PSC box
segments weighing about 35t to 50t are casted in casting yard, transported to site,
erected in position & segments are stitched together by post tensioning. Suitable
for metro viaduct construction in congested city areas.

46. Girder or Truss
2. Precast pre-stressed Concrete (PSC) U girder: U girders are precast post tensioned U
shape concrete girders of length varying from 16 m. to 28 m. (weighing about 100 t
to 165 t each) casted in single piece for one track of a span. Can be used in curves of
radius more than 400 m. Girders are casted in casting yard, transported to site and
erected in position using lifting cranes.
U girders are not suitable for viaduct in heavy congested areas due to problem in
transportation of long girders to site of erection (difficulty in manoeuvring of
narrow lanes by long road trailer.)

3. Precast pre-stressed Concrete (PSC) I girder: Precast post tensioned I girders are generally
used on sharp curves in viaduct, where PSC box girder & U girder can not be used and in
stations / approach spans of stations, housing points & crossings. PSC I girders are used for
span up to 31 m.

4. Steel I girder composite superstructure: Steel I girders with RCC deck slab are used
for spans more than 34 m. Steel I girders are fabricated in workshop, transported at site
and erected on span using cranes. RCC deck slab is casted at site on the I girders. Used
for span up to 47 m.
50. Girder or Truss
5. Steel truss composite superstructure: Steel trusses, generally known as
open web girder (OWG) with RCC deck slab are used for spans more
than 47 m.
Truss members are fabricated in workshop, transported at site and
assembled at site.
Assembly of fabricated members at site on scaffolding
51. Girder or Truss
• If OWG is to provided spanning a busy road or railway tracks, it is not possible
to assemble the truss on its final location. In such cases the truss is assembled
on one side of the abutment of bridge and then incrementally launched on its
final position. RCC deck slab is casted at site on the launched truss.

53. Girder or Truss
6. Cast-in-situ PSC segmental balanced cantilever bridge: The Balanced Cantilever
method is a construction method in which PSC box segments of superstructure
are sequentially joined to form a span by post-tensioning and balancing them
left and right from each pier using special erection equipment. The method does
not require scaffolding systems under the bridge Used for longer spans; more
than 47 m.
