Final_Presentation
This document summarizes a student project to develop sensorless control of a brushless DC motor using the third harmonic voltage signal method. The objectives are to design a control method, implement it in Simulink, and develop a circuit. BLDC motors are increasingly used due to their efficiency and reliability. Sensorless control can reduce costs by eliminating position sensors. The third harmonic method was chosen because it provides good signal-to-noise ratio and wide speed range. Key steps are extracting the third harmonic from phase voltages, and using its peaks to determine commutation points for switching the motor phases. The project involves modeling the motor and extracting the virtual neutral point in Simulink, and developing the commutation logic and starting strategy.

The document proposes a hybrid drive method for high-speed brushless DC motors that combines pulse-width modulation (PWM) and pulse-amplitude modulation (PAM) techniques. PWM control is used at low speeds for its simplicity, while PAM control is used at high speeds since it provides lower losses and higher efficiency. A phase-controlled rectifier provides adjustable DC link voltage, and virtual neutral point sensing based on three equal value resistors connected across motor terminals eliminates the need for a motor neutral wire. This hybrid drive approach aims to satisfy commutation control needs over a wide speed range and improve motor efficiency.

Managementof Loads Using Maximum Demand Meter For Commercial Sector At Peak D...
Industrial revolution in India since last 25 years has resulted in paradigm shift of residential population from
rural to urban. Thus urbanization and industrialization have resulted in unprecedented increase in electricity
demand. A direct consequence of this increased demand is the immense pressure that is build up on national
electricity grid due to excessive load. This effect is more pronounced especially during peak demand periods. It
becomes mandatory to reduce this pressure on grid in order to have reliable and continuous supply. One
solution to this problem would be the construction of additional power generating facilities, but this solution is
not economic as the installation is very costly as well as more power generating facilities will be threat to the
environment. This solution thus has to be eliminated. A more feasible solution to this problem would be an
instrument like maximum demand controller which can monitor the heavy load demand during peak hours. This
paper proposes a controller which is easy in construction and various tests carried out on it resulted in many
advantages like reduced electricity bill on recurring basis, improved load factor, and economy to the industrial
user. The users of M.D controller can recover its cost through resulted savings in recurring electricity bill.

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%.
