Introduction to Transient Disturbances of power system and its types
This presentation is brief introduction to the transient disturbances(how they occur and reason behind that) and its classification(Oscillatory and Impulsive).
Transient in Power system
The document discusses power system transients. It defines transients as pulses of very short duration but high intensity. Transients can be classified as ultra-fast, medium-fast, or slow depending on their speed. Causes of transients include lightning, switching operations, faults, and resonance. When a transmission line is energized, voltages build up gradually along it via traveling waves. The velocity and behavior of these waves are determined by the line's inductance and capacitance per unit length.
electrical transients in power system
Transient voltages, also called surges or spikes, are momentary changes in voltage or current that occur over a short period of time, usually less than 1/60th of a second. They are generated by both external sources like lightning and utility switching and internal sources like motor starts and static discharge. Transients can travel through a facility's electrical system and affect electronic equipment, causing erratic operation, lock ups, premature failure or decreased efficiency. Effective transient voltage suppression equipment can significantly increase the life of electrical and electronic systems and provide a strong return on investment.
Switching Transient Problem with Loads
This document discusses transient problems related to load switching that can cause nuisance tripping of adjustable speed drives (ASDs). It notes that ASDs use voltage source inverters with capacitors in the DC link, making them sensitive to overvoltage transients from utility capacitor switching or load switching. Such transients from load switching can generate high frequency impulses when energizing inductive loads like relays or contactors. Simultaneously energizing large transformers and capacitor banks can also cause dynamic overvoltage problems if system resonances occur. Protection methods include electrical separation of sensitive equipment, as well as using filters, isolation transformers, and shielding.

Reduction of transients in switches using embedded machine learning
Reduction of transients in switches using embedded machine learningInternational Journal of Power Electronics and Drive Systems
Non-linear loads can cause transients in electronic switches. They also result in a fluctuating output when the device is switched ON or OFF. These transients can harm not only the switches but also the devices that they are connected to, by passing excess currents or voltages to the devices. By applying machine learning, we can improve the gate drive voltages of the switches and thereby reduce switch transients. A feedback system is built that measures the output transients and then feeds it to a neural network algorithm that then gives a proper gate drive to the device. This will reduce transients and also improve performances of switch based devices like inverters and converters.Faults on Power System
Electrical fault is the deviation of voltages and currents from nominal values or states. Under normal operating conditions, power system equipment or lines carry normal voltages and currents which results in a safer operation of the system.
distance relay
This document discusses different types of distance relays used for transmission line protection. It describes impedance, reactance, and admittance relays. An impedance relay operates based on the ratio of voltage to current, with a torque proportional to current and restraining torque proportional to voltage. During a fault, the impedance ratio decreases and trips the circuit breaker if it falls below a predetermined value.

Prof. S. Rengarajan presented a technical seminar on ferroresonance in transformers. Ferroresonance occurs when a no-load transformer is disconnected from the power source, causing overvoltages and overcurrents. It was analyzed using ATP-EMTP software, showing high voltage and triangular current waveforms. Ferroresonance can damage transformer insulation if voltages exceed ratings. Mitigation methods include connecting a load to the secondary winding or an RC suppressor to dissipate resonant energies when disconnecting no-load transformers.

Inrush current reduction in three phase power transformer by using prefluxing...
This document discusses reducing inrush current in power transformers. It begins by introducing transformers and explaining that inrush current can be up to 10 times the nominal current and cause issues. One method to reduce inrush current is point-on-wave switching, which controls energization based on residual flux. However, measuring residual flux is difficult. The paper proposes a prefluxing technique which sets the initial flux in the transformer before energization using controlled switching. It models a 300MVA, 11/400kV transformer in MATLAB and compares inrush current reduction using point-on-wave switching and prefluxing. The aim is to minimize the peak inrush current and reach steady state current faster.
Fundamentals of transformer inrush
This document discusses transformer inrush current and its impact on differential relays. Transformer inrush occurs when the flux in the transformer core needs to be established, causing a large magnetizing current to flow. This inrush current appears as a differential current that can cause misoperation of transformer differential relays. The document examines characteristics of inrush current like the switching point, remnant flux, system impedance, and transformer design. It also discusses various harmonic-based methods for restraining differential relays during inrush like percentage of total harmonic, percentage of 2nd harmonic, and adaptive 2nd harmonic methods. The considerations for applying these methods include reliability, security, and speed of operation.
Over current protection
The document discusses over current protection in electrical systems. It describes over current as a situation where excess current flows through a conductor, risking heat generation and equipment damage. Possible causes of over current include short circuits, excessive load, incorrect design, or ground faults. Over current relays protect systems by detecting excess current from current transformers and tripping circuit breakers. Relays are classified based on their time of operation as instantaneous, definite time, or inverse time relays. The document outlines various over current protection schemes used in electrical equipment like transformers and generators.
Ground fault protection
1. Ground Fault Protection (GFP) devices are used to protect electrical installations from fire risks by quickly detecting insulation faults.
2. GFP devices operate by measuring residual fault currents, which involves monitoring the vector sum of all live conductor currents and tripping the circuit if it exceeds the device's threshold.
3. Standards like IEC 60 364 and the National Electrical Code (NEC) require the use of GFP or Residual Current Devices (RCD) depending on the earthing system, with the NEC specifying very low sensitivity GFP devices for North American TN-S systems to address fire risks from potential high fault currents.

POWER QUALITY ISSUES & SOLUTIONS - FELIDAE SYSTEMS
Power quality refers to how well an electrical system delivers power to devices without loss of performance. Poor power quality can cause devices to malfunction or fail prematurely. Harmonics from nonlinear loads are a major cause of power quality issues, distorting the voltage and current waveforms which increases losses and equipment ratings. Modern systems with power electronics also introduce harmonics, so techniques are needed to suppress distortion for both utilities and users.

The document summarizes research on using a resistive superconducting fault current limiter (SFCL) to improve the transient performance of microgrids. It describes how SFCLs can quickly limit fault currents while maintaining low impedance during normal operation. The modeling and control of an SFCL integrated into a microgrid is presented, showing how the SFCL allows the microgrid to smoothly transition between grid-connected and island modes by limiting faults. Simulation results demonstrate how the SFCL maintains voltage and reduces frequency oscillations during a fault compared to without an SFCL. Future applications and research on SFCLs are also discussed.

Presentation on Image Compression
This document provides an overview of image compression techniques. It discusses how image compression works to reduce the number of bits needed to represent image data. The main goals of image compression are to reduce irrelevant and redundant image information to produce smaller and more efficient file sizes for storage and transmission. The document outlines different compression methods including lossless compression, which compresses data without any loss, and lossy compression, which allows for some loss of information in exchange for higher compression ratios. Specific techniques like run length encoding are also explained.
Thesis on Image compression by Manish Myst
The document discusses using neural networks for image compression. It describes how previous neural network methods divided images into blocks and achieved limited compression. The proposed method applies edge detection, thresholding, and thinning to images first to reduce their size. It then uses a single-hidden layer feedforward neural network with an adaptive number of hidden neurons based on the image's distinct gray levels. The network is trained to compress the preprocessed image block and reconstruct the original image at the receiving end. This adaptive approach aims to achieve higher compression ratios than previous neural network methods.

Multilevel inverters have become more popular over the years in electric high power application
with the promise of less disturbances and the possibility to function at lower switching frequencies than
ordinary two-level inverters. This paper presents information about several multilevel inverter topologies,
such as the Neutral-Point Clamped Inverter and the Cascaded Multi cell Inverter. These multilevel
inverters will also be compared with two-level inverters in simulations to investigate the advantages of
using multilevel inverters. Modulation strategies, component comparison and solutions to the multilevel
voltage source balancing problem will also be presented in this work.

Concurrent Detection and Classification of Faults in Matrix Converter using T...
This paper presents a fault diagnostic algorithm for detecting and locating open-circuit and short-circiut faults in switching components of matrix converters (MCs) which can be effectively used to drive a permanent magnet synchronous motor for research in critical applications. The proposed method is based on monitoring the voltages and currents of the switches. These measurements are used to evaluate the forward trans-conductance of each transistor for different values of switch voltages. These trans-conductance values are then compared to the nominal values. Under healthy conditions, the values obtained for the fault signal is less than the tolerable value. Under the open/short-circuit conditions, the fault signal exceeds the threshold, hence enables the matrix converter drive to detect and exactly identify the location of the faulty IGBT. The main advantages of this diagnostic method include fast detection and locating of the faulty IGBT, easiness of implementation and independency of the modulation strategy of the converter.
Transmission and Distribution.
- Transmission and distribution is the infrastructure that transports electricity from generation sites over long distances to users.
- There are various levels in a power system including generation, transmission, and distribution with different standard voltages used at each level. In India, generation is typically at 400kV, transmission at 400kV, 220kV, and 110kV, and distribution at 33kV and below.
- High voltage transmission allows for lower transmission losses and reduced material costs. However, it requires special insulation and safety precautions to handle the high voltages involved.

Power electronics deals with applying electronic principles to power-level situations rather than signal-level. It involves devices like power diodes, thyristors (SCRs), and transistors (BJT, MOSFET, IGBT) that can control high currents and voltages. A thyristor maintains conduction below its holding current and latches on above its latching current. Snubber circuits protect thyristors from high dv/dt. Controlled rectifiers use thyristors to vary DC output voltage. Choppers vary DC voltage using switching circuits. Inverters convert DC to AC. AC voltage controllers vary AC output voltage using phase control or on-off control of thyristors. Cycloconverters directly convert AC power

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%.
