Audio De-noising using Adaptive Inertia Weight Particle Swarm Optimization Algorithm (AIW-PSO)
Abstract: There has been a lot of research in Audio de-noising so far but scope for improvement is always there. The motivation to use AIW-PSO algorithm as a possible alternative is to explore new ways to reduce global cost and to achieve better noise reduction performance. Particle swarm optimization is a heuristic stochastic evolutionary algorithm. However, standard PSO provides unbalanced exploration and exploitation. This paper presents a methodology to improve the …

Design of Active Power Based Relay Algorithm to Overcome Transient Instability: 220 kV Amravati Substation Case Study
Abstract: This paper presents a new protective scheme, i.e. new relay algorithm to protect small scale generators against transient instability. The demand of installing small generators in distribution networks has been increased now-a-days. Small scale generators have low inertia constant. The inertia constant minimizes the frequency deviation which depends on the kinetic energy. Therefore frequency dynamics becomes slower and hence it increases the response time to react to fault events. Due …
