Near-Surface Seismic Refraction Tomography; a case study for geotechnical application
Abstract: Usually, among geophysical techniques, seismic refraction methods are used to investigate near surface geology for engineering purposes. In these study physical parameters, longitudinal seismic wave velocities were used to characterize the shallow subsurface layers for geotechnical application. The physical response of subsurface materials varies as the structure, porosity, fluid saturation, composition and tie-up vary. These variations primarily viewed in the first arrival time of seismic waves. With the necessary steps, …

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 …
