Modern Power System Protective Relaying

Modern Power System Protective Relaying

Code Date Venue Fees
EL006 17 - 21 Dec 2017 Dubai - UAE $4,500 Register

Introduction

Protection systems are installed to prevent faults from damaging electrical plant and to initiate isolation of faulted sections in order to maintain continuity of supply elsewhere on the system. Recent changes in technology together with changes in the manner in which Utilities and Industrial organisations operate, has greatly emphasized the development of integrated protection and control.

Modern relays include facilities such as monitoring and recording capabilities, self diagnostics and permit adjustment of setting by remote control. In short, the role of the modern protection relay is primarily to act in a fault situation but increasingly finds application in transmitting information in connection with the operation of the system. It is however the relay response to fault situations that forms the principal thrust of the current course.

This course will cover:

  • Power System Fault Analysis
  • Current and Voltage transformers
  • Over Current and Earth Fault Protection
  • Pilot Wire and Distance Protection
  • Transformer, Generator and Motor Protection
  • Busbar Protection
  • Protection Settings and Grading

Objectives

Participants will gain a detailed appreciation of the following:

  • The nature of different types of electrical faults and the effect these faults can have on company assets
  • Understanding of electrical fault protection systems
  • Practical solutions for specifying and operating protection systems
  • Comprehensive understanding of principles and selection of protection relays and protection schemes
  • The requirement for testing of relays and protection systems

Training Methodology

Each course participant will receive a copy of the comprehensive course notes. The presenter will outline and discuss the topics using computer displays, CD displays and Videotapes. The course is designed to have an interactive format to maximize delegate participation. Questions and answers are encouraged throughout and at the daily sessions. Needs-based case-studies and examples will be discussed in problem solving workshop sessions.

Organisational Impact

  • The course will allow delegates to interact and gain from shared experiences of others
  • Carefully selected examples and case studies will be used to illustrate the material being discussed
  • Emphasis will be given to ensure that the material is appropriate to the organisations represented
  • Understand the concept of protection system discrimination and appreciate its importance in improving security of supply
  • An awareness and understanding of the modern power system protective relays and understand their basic operation

Personal Impact

  • Understand the electrical characteristics of various electrical faults
  • Identify different types of protection systems, understand the purpose of each type of protection system and identify the zone of protection for a given relay
  • Recognize modern protective relays and understand their basic operation
  • Appreciate the characteristics and importance of voltage transformers and current transformers in achieving dependable and accurate electrical protection systems
  • Be familiar with the requirements for testing of protection systems

Who Should Attend?

  • Engineers and Senior Technicians from Electrical Utilization Companies and Industrial organisations
  • Building and Services Professionals, who have to deal with the aspects of electrical and industrial power systems protection, control and operation will also find the course beneficial. Participants need no specific requirements other than good understanding of electro technology and some relevant experience.
