Transmission & Distribution Operation & Design Calculations

Course Overview

This Transmission & Distribution Operation & Design Calculations training course has been designed to provide a good understanding of power system concepts, theories, parameters, and the way such information is analyzed by means of equations, curves, diagrams, and tables.

This Electrical Engineering training course is in fact a quick review on electrical engineering principles and focuses on the technical specifications, operation, and behaviour of power system main equipment such as power transformers, distribution transformers, switchgears, circuit breakers, earthing switches, auto-reclosers, transmission lines, busbars, and protection and control systems.

Nowadays, the significant trend in load increase in industrial centres, shopping malls, and residential areas requires upgrading and enlargement of power systems and utility grids. This can be achieved by designing highly reliable busbar configurations, interconnecting transmission lines, zone substations, and distribution centres, and also by expanding power plants and embedded generation facilities in appropriate locations.

As a result, the operation decisions and switching regimes of power networks are continually becoming more complex due to the complicated load flow patterns, complex protection schemes, modern digital technology, and the numerous scenarios for power flow and load dispatch which must be decided upon by system operators and network managers.

Therefore, maintaining power performance criteria such as reliability, voltage stability, and frequency stability would be of utmost importance in a reliable power system. In other words, by gaining a good knowledge about how system parameters would change under different system operation modes, or different loading, or switching, one can better understand the behaviour of the power system (which is under study); as such the response of the system to different switching scenarios and setting changes would be more predictable.

This GLOMACS Transmission & Distribution Design Calculations training course will highlight:

  • Power system parameters
  • Power flow equations
  • Transmission lines design and operation
  • Power & distribution transformers
  • Distribution system configurations and design
  • Switchgear types and construction
  • HV cable sizing and coefficient factors
  • Power system protection

Training Objectives

At the end of this Transmission & Distribution Design Calculations training course, you will learn how to:

  • Model a power system by means of system parameters
  • Create different load flow scenarios through different switching regimes
  • How to analyze and interpret the response of the power system to different scenarios
  • How to modify the power system behaviour in an area by enhancing system parameters
  • Create and analyze protection curves to achieve coordination between different bays

Training Methodology

This Transmission & Distribution Operation & Design Calculations training course will be presented by means of power point slides through which all the required theory and equations will be provided. This 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.
