Introduction

In the intricate and ever-evolving landscape of modern power systems, maintaining dynamic stability is paramount for reliable and secure operation. The increasing penetration of renewable energy sources, the complexity of interconnections, and the growing demand for electricity introduce dynamic challenges that cannot be fully assessed with steady-state analysis alone. PSS/E (Power System Simulator for Engineering) is a widely recognized and industry-standard software tool specifically designed for comprehensive power system analysis, with a strong focus on dynamic system studies. It enables engineers to simulate the transient and dynamic behavior of power systems following disturbances, ranging from sudden load changes and generator trips to fault conditions and control system responses. By accurately modeling synchronous machines, exciters, governors, and various control devices, PSS/E empowers engineers to predict system stability limits, design effective control strategies, and ensure grid resilience. Without proficiency in PSS/E for Dynamic System Studies, power system professionals would lack the essential tools to rigorously analyze, predict, and mitigate these critical dynamic behaviors, underscoring the vital need for specialized training in this powerful simulation environment. This comprehensive training course focuses on equipping professionals with the expertise to master PSS/E for Dynamic System Studies.

This training course is meticulously designed to empower electrical engineers, power system analysts, system planners, control system designers, and researchers with the theoretical understanding and practical skills necessary to effectively utilize PSS/E for Dynamic System Studies. Participants will gain hands-on experience in building and managing detailed dynamic models, performing various types of stability analyses, interpreting complex simulation results, and designing mitigation strategies for dynamic phenomena. The course will delve into topics such as modeling synchronous and asynchronous machines, implementing exciters and governors, performing transient stability analysis, analyzing small signal (modal) stability, designing and tuning Power System Stabilizers (PSS), simulating HVDC and FACTS device dynamics, and conducting voltage stability studies. By mastering the principles and practical application of PSS/E for Dynamic System Studies, participants will be prepared to accurately diagnose and solve complex dynamic problems, enhance grid reliability and resilience, optimize system design, and contribute significantly to the advanced planning and safe operation of modern electrical grids.
