Course Outline
Description: Electric Power Systems are presently undergoing major transformative changes. The need to enhance power system stability in the wake of recent blackouts is being increasingly felt by power system planners and operating engineers. The transmission network is highly stressed and operating much below its thermal capacity. There is a perennial requirement of optimally utilizing existing transmission assets as compared to building new transmission facilities. The government emphasis and incentives for increasing the penetration of renewable energy sources in power systems have led to novel issues in power system operation. A thorough understanding of the basic power system principles is required to address these challenges. This seminar is geared to provide a comprehensive understanding of fundamental concepts of electric power systems. A large number of solved examples will be shown to enhance the understanding theoretical concepts. This seminar is a MUST for anyone who is involved in power system planning, design and operation. Objectives The objective of this course is to provide a detailed understanding of the basic components of modern power systems; their modeling and operating principles. The course will present an introduction to three phase transformers and transmission lines. Steady state analysis of power transmission lines under normal conditions will be discussed. Power flow studies, power system fault analysis under both symmetrical and unsymmetrical conditions, and power system stability studies will be covered in depth. Who Should Attend Electrical Power System Engineers, Managers, Power System Designers and Planners, Power System Operators, Technologists, and other technical personnel should attend this course. This seminar will be valuable for all those who wish to acquire or refresh knowledge of power systems concepts and utilize these in solving modern day power system problems.
