Modern Power System Protective Relaying
Introduction
This LAKESHORE ISL Modern Power System Protective Relaying training seminar has been designed to provide a clear and perfect understanding of power system protection schemes and devices including protection relays, fuses, circuit breakers, and other protective devices. In modern power systems, nowadays, protection systems play a significant role in efficiently running plant operations, utility switching, industry load transfer, maintenance programs, and investment policies. The outcome is to minimize system outages and to keep the maintenance and repair costs at reasonable prices. With the advancement of technology, now there is need for many system operators, electrical engineers (at all levels of proficiency), asset engineers, and project engineers to learn more about the power system protection concepts, logic, and applications to acceptable levels.
These days, advanced protection devices are considered as Intelligent Electronic Devices (IED’s) in all modern smart grids where protection schemes, logic, and relay settings rely heavily on a good understanding of communication protocols, inter-tripping schemes, etc. This LAKESHORE ISL Electrical Engineering training seminar will provide sufficient theoretical background in a simple language together with a systematic procedure to analyze electric faults, their consequences, and recommended solutions through industry-based practical worked examples and mini projects to achieve an optimized and coordinated operation of protective devices in typical moderately complex power systems.
This LAKESHORE ISL training seminar will highlight:
- Electric Fault Types and Fault Calculations
- Load Studies
- Protection Relay Types and Functions
- Protection Logic and Settings
- Coordination of Protection Devices
Objectives
At the end of this LAKESHORE ISL training course, you will learn how to:
- Select fit-for-the-purpose protection relays and other related devices
- Calculate fault levels and loadings of feeders and branches
- Develop and analyze typical power systems and their associated protection systems
- Analyze protection logics and coordination between protection devices
- Establish communication between protection devices and controllers
Training Methodology
This LAKESHORE ISL Modern Power System Protective Relaying training course will be presented by means of Power Point slides through which all the required theory and equations will be provided. This LAKESHORE ISL Electrical Engineering training course also includes case studies where the participants are required to take part in class activities including system analysis, calculations, relay settings, etc. The instructor will also use training videos for better understanding of the participants. The participants will be progressively assessed during the training course via quizzes, questions, assignments, and worked examples.
