Course Description
Power systems equipment must withstand not only the rated voltage, which corresponds to the highest voltage of a particular system, but also expected short level. Accordingly, it is necessary to set protective relays based on these results obtained from short circuit study. One of hot issues now related to these is arc flashing study which is mainly based on the studies of short circuit and relay co-ordination as well. All these three issues should be dealt as integral parts & bulk. Power System Analysis means verifying the adequacy of the power distribution system and it's components, recognize coordination related disturbances and outages and collecting the required data to perform a detailed required study. The course is mainly designed to maximize delegate’s benefits from utilizing the vast capabilities of ETAP in the modeling and simulations. Intensive simulations will be utilized during course sessions using ETAP power station from OTI Version 20.6/21.02. Strictly, 80% of the course period is dedicated to hands-on ETAP software and 20% for lecturing technical backgrounds. To sum up, to provide participants with a solid understanding of power system analysis concepts and how to apply these concepts using ETAP software. Participants will learn to analyze, model, and simulate various power system scenarios, including steady-state and transient conditions.
