Introduction

This GLOMACS Transmission & Distribution Operation & Design Calculations training seminar 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 GLOMACS training seminar 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 & setting changes would be more predictable.

This GLOMACS 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

Objectives

At the end of this GLOMACS 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 GLOMACS Transmission & Distribution Operation & Design

Calculations training seminar will be presented by means of power

point slides through which all the required theory and equations

will be provided. This GLOMACS training seminar 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 seminar via quizzes, questions, assignments, and worked

examples.

Organisational Impact

On successful completion, the organizational impact would be:

• Develop a structured approach to selection of voltage levels and

loadability of transmission systems

• Determine minimum technical requirements to achieve

transmission reliability & stability

• Learn about the effects of major power disturbances on

transmission systems and their solutions

• Practice on distribution system design calculations and safety

precautions

• Correct selection of O/H conductors and U/G cables

Personal Impact

Participants from different sectors of engineering companies will enormously benefit from this GLOMACS training programme because they will become quite familiar with:

• Mathematical approach to the interpretation and analysis of

system disturbances

• Design, operation, and protection of distribution and transmission

systems

• Installation & construction switchgears and transformers

• Power system switching & operation together with proposed

solutions

• Protection coordination, selectivity, sensitivity, and stability
