AC Distribution in Bangladesh (in a nutshell)
Power System is an integrated network that interconnects the installations for generation, transmission and distribution of electricity. In Bangladesh electricity is generated at 50 Hertz frequency and at a nominal voltage of 11 KV (Kilo Volts) or 15 KV to be stepped up through transformers to 132 kV or 230 kV for feeding to the grid i.e. a high voltage transmission network that transmits the power to grid substation transformers to be stepped down at 33 kV. 11 kV and 0.4 kV for delivery to the consumers of various categories.
Impedance Matching
In electronics, impedance matching is the practice of designing the input impedance of an electrical load or the output impedance of its corresponding signal source to maximize the power transfer or minimize signal reflection from the load.
Transmission Line Constraints
Loadability of line is defined as the extent of load which can flow through the line without exceeding the limitations. Line Loadability is expressed in percentage of Surge Impedance Loading of line. The limiting factor for line loading are: thermal limit, voltage drop limit and steady state stability.
Equipment and Stability Constraints : System Operation
There are two types of constraints which limit the capability of a power system: If the overloading exceeds limits, the equipment is tripped out by protection systems. b) Stability Constraints: A power system may not be able to cater to power flows beyond a certain point due to stability constraints.
Power System Control
A power system control is required to maintain a continuous balance between power generation and load demand. Load Frequency Controller and Automatic Voltage Regulator play an important role in maintaining constant frequency and voltage in order to ensure the reliability of electric power.
Issues in Interconnections
HVDC stands for high voltage direct current, a well-proven technology used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems, where traditional alternating current (AC) connections cannot be used.
Hydro Power Plant
A hydro power plant uses water as its fuel source and must be located near a reliable water source like a river or canal. The type of plant depends on factors like water availability and head. Site selection considers water storage capacity, head height, proximity to load centers, transportation access, and available affordable land. Key components of a turbine include the runner, diffuser, and optional distributor.
Steam Power Plant and Rankine Cycles
This document discusses methods to improve the efficiency of a Rankine cycle steam power plant. It describes lowering the condenser pressure, superheating steam to high temperatures using reheat, increasing the boiler pressure, implementing an ideal regenerative Rankine cycle with open feedwater heaters, using closed feedwater heaters, and utilizing cogeneration to make use of waste heat. The key methods discussed are lowering condenser pressure, superheating steam, increasing boiler pressure, and implementing regenerative feedwater heating to improve the average heat addition and cycle efficiency.
Steam Power Plant
The steam-electric power station is a power station in which the electric generator is steam driven.
The Rankine cycle or Rankine Vapor Cycle is the process widely used by power plants such as coal-fired power plants or nuclear reactors. In this mechanism, a fuel is used to produce heat within a boiler, converting water into steam which then expands through a turbine producing useful work.
AC Distribution System in Bangladesh

1. Distribution Procedure
2. Primary and Secondary Distribution System
3. Distribution Substation
4. Distribution Companies
5. Distribution in both City and Rural Area
6. Distribution Loss
7. Protective Devices

Power System Stability
Power system stability is the ability of an electric power system, for a given initial operating condition, to regain a state of operating equilibrium after being subjected to a physical disturbance, with most system variables bounded so that practically the entire system remains intact.
Economic Operation of Power System
Economic operation of power system. (i) One dealing with minimum cost of power production called Economic dispatch. (ii) Other dealing with minimum loss of the generated power delivery to the loads. For any specified load condition, economic dispatch (i) determines the power output of each plant.
Unsymmetrical Fault
Faults where the rock layers on one side of the fault plane have moved differently than the layers on the other side are called unsymmetrical faults. The three main types of unsymmetrical faults are normal faults, reverse faults, and thrust faults. Normal faults occur when the rock layer above the fault plane drops down relative to the layer below, reverse faults happen when the layer above moves upward relative to the layer below, and thrust faults are similar to reverse faults but involve much larger displacements of rock.
Symmetrical Components and Sequence Networks
Symmetrical components and sequence networks are methods for analyzing unbalanced three-phase power systems. These techniques allow engineers to examine the individual balanced and unbalanced components that make up the total system. Symmetrical components and sequence networks break down polyphase systems into separate balanced and unbalanced parts that can be analyzed independently and then recombined to determine the behavior of the full unbalanced system.
Symmetrical Fault
A symmetrical fault is an electrical fault where the same fault condition exists on all phases of a three-phase power system. This occurs when all phases experience either an open circuit condition or a short circuit to ground or another phase. A symmetrical fault disrupts the balance between all phases equally.
Power Flow Solution
Power systems engineers must ensure that electricity is delivered reliably and efficiently from generators to consumers. To do so, they use power flow analysis to model how power will flow through transmission lines, transformers, and other equipment under different conditions.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

blood donors such as Name, Number, Address, Blood Group, rather than searching it on
the different websites and wasting the precious time. This application is effective and
user friendly.
Bituminous road construction project based learning report
Road construction is not as easy as it seems to be, it includes various steps and it starts with its designing and
structure including the traffic volume consideration. Then base layer is done by bulldozers and levelers and after
base surface coating has to be done. For giving road a smooth surface with flexibility, Asphalt concrete is used.
Asphalt requires an aggregate sub base material layer, and then a base layer to be put into first place. Asphalt road
construction is formulated to support the heavy traffic load and climatic conditions. It is 100% recyclable and
saving non renewable natural resources.
With the advancement of technology, Asphalt technology gives assurance about the good drainage system and with
skid resistance it can be used where safety is necessary such as outsidethe schools.
The largest use of Asphalt is for making asphalt concrete for road surfaces. It is widely used in airports around the
world due to the sturdiness and ability to be repaired quickly, it is widely used for runways dedicated to aircraft
landing and taking off. Asphalt is normally stored and transported at 150’C or 300’F temperature

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
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%.
