Modern Power System Protective Relaying

Introduction

This GLOMACS Modern Power System Protective Relaying training course 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.

Today, 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 will provide enough theoretical background in a simple language together with a step-by-step procedure to analyze electrical faults, their consequences, understanding of the characteristics of the time-current curves and the efficient numerical relay functionalities.

This GLOMACS training course will highlight:

• Electric Fault Types and Fault Calculations
• Electrical Protection Fundamentals
• Protection Relay Types and Functions
• Protection Logic and Settings
• Coordination of Protection Devices
