COURSE OVERVIEW
Power system protection systems play a crucial role in establishing reliable electrical power systems. Poorly designed protection systems may result in major power failures. Due to the increasing importance of electricity, such power failures can have a serious impact on society and the economy.
Knowledge of power system protection systems is key when it comes to optimizing the reliability level of electrical infrastructures. With the advances in protection and communication technology in recent decades plus the strong increase of renewable energy sources, the design and operation of power system protection systems has become ever more challenging.
This training course presents the fundamentals of power system protection and its application. A very “hands-on” is used to teach the concepts. Understanding is reinforced with real world examples. Interaction is encouraged between participants and the presenters, to underpin the learning objectives.
Throughout the course, Engineers will have an opportunity to be exposed to learn more about relay coordination for power system protection by using commercial IEDs (Intelligent Electronic Device). It will facilitate to get skills for calculating settings and testing of protection operation conditions.
Completing this course will charge you for:
- Identify the challenges and solutions to industrial power system protection problems
- Select the appropriate protection schemes for various applications
- Able to analyze power system faults for balanced and unbalanced conditions
- Able to analyze time coordination curves (TCC) to verify the coordination between upstream and downstream protection devices including fuses & sequence of operation of protection devices
- Identify, apply, and calculate settings for overcurrent, directional overcurrent, distance, differential and pilot protection schemes
- Identify, apply, and calculate settings for power lines, transformer, generator and bus bar protection schemes
- Develop an understanding of the most common types of protection & apply the theory to a range of practical examples.
- Select proper sets of relays and to measure characteristics of protection
- Understand how to determine relay settings, and/or evaluate systems designed by others
- Familiarize with International Industries Norms (IEEE 242, IEEE 3004, IEEE 399, IEC 60255 etc.)
Who is the course for?
