Pre-requisite Courses and Assumed Knowledge and Capabilities

You must be able to analyse single-phase & three-phase circuits, transformer equivalent circuits as covered in the  EEET1316Electrical Systems course.
You must have the mathematical skills to work with matrix algebra, complex numbers, vectors, first and second order differential equations.

Course Description

The goal of this course is to provide you with the knowledge of the components of electrical energy supply systems and how the components work together to deliver electric power stably and safely. The construction and performance of synchronous generators, the modelling of transmission lines for steady state and transient conditions, balanced and unbalanced fault analysis are boradly considered in this course.  

Objectives/Learning Outcomes/Capability Development

The capabilities that you will learn, develop and exercise in this course are:

  •  Theoretical knowledge: Application of physical laws to develop mathematical models of Energy Systems.
  •  Technical ability:  With emphasis on problem solving and laboratory work, this course prepares you to be able to analyse Electrical Energy systems in a systematic manner and to predict and shape the behaviour of energy systems.
  •  Communication and working in teams: Your capabilities will be improved through group work in laboratory assignments, and through the presentation of written and verbal reports.
  •  Independent and life long learning: You will be directed, throughout the course, to read specific sections of the prescribed text book and to attempt a number of self assessment questions.

At the end of this course you will be able to:

  •  Model the power system components for steady state analysis.
  •  Describe how a synchronous Generator is constructed with specific details of winding arrangements. Explain how the spatial flux produced by balanced three phase currents in ideally distributed three phase windings results in a rotating magnetic field.
  •  Draw the circuit model of a generator in terms of synchronous reactance and describe the OC and SC tests used to calculate the synchronous reactance.
  •  Calculate the synchronous reactance from the OC and SC test results. Calculate ‘Power angle” of a generator and sketch the power angle characteristics. Recognise that large (close to 900) power angle leads to instability.
  •  Determine the effects of varying the dc excitation current on the stator current of a generator supplying fixed loads. (V – curves)
  •  Determine and draw the limiting boundaries of the operating range. (Capability curve)
  •  Calculate the model parameters from the physical characteristics.
  •  Calculate the power transfer capability of transmission lines.
  •  Calculate the voltage, current and power at the line terminals.
  •  Calculate currents through the components and voltage sags at various points under balanced fault conditions.
  •  Derive the symmetrical components of unbalanced voltages/currents.
  •  Model the networks in terms of sequence networks.
  •  Calculate the fault currents and voltages when unsymmetrical faults occur.

Overview of Learning Activities

This course provides you with a number of learning opportunities:

  •  There are weekly lectures(2) which will give you detailed explanation of technical matters and guide you to important concepts.
  •  There are weekly readings which will give you the necessary background information and provide a broader context to the materials discussed at lectures.
  •  There are weekly tutorials  where you can get help with the problem solving activities. There are problem sheets for you to try and self asses your understanding.
  •  There is a course website with links to online resources for you to self access and expand your knowledge of the topics.
  •    You will be involved in group work to develop your team and negotiation skills.
  •  There is a learning guide that provides you with course notes and learning activities that you can self access.
  •  There are simulations on the course website for you to learn and self access.
  •  There are worked problems on the course website to guide you .
  •  There are extra problems provided in the learning guide to give you practice.
  •  There are learning activities specified to give you extra guidance.
