ENHANCED GRID FAULT DETECTION SYSTEM USING AI

Abstract

The increasing complexity of power grids, driven by the. integration of renewable energy sources and the demand for uninterrupted power supply, has intensified the need for advanced fault detection mechanisms. Traditional fault detection systems;· • reliant . on static thresholds and conventional monitoring techniques, often struggle to meet the demands of modem, dynamic grid environments. This paper presents an Enhanced Grid Fault Detection System using Artificial Intelligence (AI), designed to address these challenges by enabling real-time, accurate, and efficient fault detection and mitigation. Leveraging machine learning algorithms, the proposed system processes vast amounts of sensor data from across the grid, identifying and classifying faults with high precision. The AI model incorporates both historical and real-time data, enabling predictive maintenance and fault prediction to proactively address potential issues before they escalate. Additionally, the system's adaptive capabilities facilitate quick recovery from faults by rerouting power flows, reducing downtime, and enhancing grid stability. This AI-enhanced approach not only boosts operational efficiency but also strengthens grid resilience, ensuring a sustainable power supply amidst evolving energy demands. The system's scalable design makes it adaptable to both current grid architectures and future smart grid expansions, highlighting its potential as a cornerstone technology for reliable and efficient power grid management.

Description of the System:
)- Quantum computing and deep learning have recently gained popularity
across vario_us . industries, promising revolutionary advancements. The
authors introduce QC-PCSANN-CHIO-FD, a novel approach that
enhances fault detection in electrical power systems by combining
quantum computing, deep learning, and optimisation algorithms.
)- The network, based on a Pyramidal Convolution Shuffle Attention Neural
Network (PCSANN) optimised with the Coronavirus Herd Immunity
Optimiser, shows promising results. Initially, historical datasets are used
for fault detection. Preprocessing, which includes handling missing data
and outliers using Adaptive Variational Bayesian Filtering is followed by
Dual-Domain Feature Extraction to extract grayscale statistical features.
)- These features are . processed by PCSANN to detect faults. The
Coronavirus Herd Immunity Optimisation Algorithm is proposed to
optimise PCSANN for precise fault detection. Performance of the
. proposed QC-PCSANN-CHIO-FD approach attains 24.11%, 28.56% and
22.73% high specificity, 21.89%, 23.04% and 9.51% lower computation
Time, 25.289%, 15.35% and 19.91% higher ROC and 8.65%, 13.8%, and
7.15% higher Accuracy compared with existing methods, such as combining deep learning based on quantum computing for electrical power system malfunction diagnosis (QC-ANN-FD), electrical power
system fault diagnostics using hybrid quantum-classical· deep )earning
(QC-CRBM-FD), applications of machine learning to the identification of
power system faults: Recent developments and future directions (QC-RFFD).
~ An important component of electrical power systems is fault analysis and
diagnosis, which is crucial in managing serious failures brought on by the
cascade effects of defects. Critical issues such as blackouts and
unwelcome voltage and current fluctuations can be prevented by
implementing prompt preventative measures, which needs for quick and
precise fault identification techniques.
~ This requirement drives the growth of novel error identification and
analysis techniques that identify and locate potential irregularities in
electrical power systems to prevent performance deprivation. For the
purpose of diagnosing power system faults, a number of expert systems,
such as rule-based techniques, have previously been presented. Due to
their incapacity to learn from mistakes and their difficulties consistently
obtaining knowledge from experts, these approaches do have some limits.
~ Process history-based defect diagnosis approaches do not require a
description of the underlying processes when creating a mapping from
inputs to appropriate outputs. When diagnosing power system faults, these pattern recognition techniques are credited with increased effectiveness and robustness to modelling flaws. Quantum computing
(QC) is ushering in new emerging computational technology and has the
ability to affect issues on global scale. QC is subject to employ quantum
mechanics theories to resolve complicated issues in variety of areas,
including computer optimisation, machine learning. QC has received
considerable attention from the scientific community. in recent years.
Therefore, a viable approach for defect analysis and diagnosis involves
utilising complementary characteristics of quantum and classical
computers to create hybrid pattern recognition techniques and get over
constraints. However, it has the major problems associated to the
following factors difficult to understand, complex operations, time
consuming, and error results. Subsequently, in this work QC-PCSANNCHIO-
FD is incorporated for getting better results in fault detection.
These motivate us to carry out this research work.
>- In this paper, an innovative approach that leverages the capabilities of
quantum computing, deep learning, and advanced optimisation
algorithms to significantly enhance the accuracy of fault detection in
electrical power systems is proposed. The proposed network, termed QCPCSANN-
CHIO-FD, integrates several cutting-edge technologies to
achieve this goal.
>- Quantum computing is utilised to perform complex computations at speeds, which is crucial for processing the vast amounts of data generated by modern power systems. By using quantum algorithms,
optimisation problems is solved more efficiently than classical methods .
. · :.
~ Deep learning component 9f the system is based on a pyramidal
convolution shuffle attention neural network (PCSANN). This
architecture enhances the model's ability to focus on the most relevant
features of the data, improving its ability to detect and classify faults
accurately. The pyramidal structure allows the network to capture
hierarchical features, while the shuffle attention mechanism helps in
prioritising important information.
~ The optimisation algorithm employed is the coronavirus herd immunity
optimiser. Inspired by the concept of herd immunity, this optimiser
mimics the way populations develop immunity to viruses, enhancing the
network's performance through adaptive learning strategies. CHIO
adjusts the parameters of the neural network to find the optimal
configuration for fault detection.
~ Principles from epidemiology, particularly herd immunity, are applied to
improve fault detection in electrical power systems by drawing parallels
between the expansion of fault and the propagation of faults. This
integration involves adapting concepts, such as immunity and contagion
to the context of power systems. Engineers leverage these principles to design more resilient and reliable power infrastructure.
