Description:
| Aims: * To develop a knowledge and understanding of the fundamental concepts of electrical energy system operation, analysis and fault diagnosis.
* To provide a thorough understanding of the operation and design of the principal types of AC plants and to provide models for the calculation of plant performance.
* To provide students with an insight into, and an understanding of, analytic methods applied to electrical energy system analysis.
Learning Outcomes: At the end of the unit students will be able to:
* Calculate the performance of key plant including transformers.
* Carry out analyses of symmetrical and asymmetrical fault conditions in electrical energy systems.
* Perform a multi-node load flow analysis and exercise an informed choice over the solution technique.
* Explain the techniques of dc power transmission including its benefits compared to ac transmission.
* Analyse transients on power systems caused by switching operations or faults for both single and multi-phase situations.
Skills: The programme should instil the ability critically evaluate engineering systems, across traditional boundaries. To this end students will learn to:
* Recognise the principal subsystems of a modern power network.
* Recognise and explain the functional purpose of each subsystem.
* Apply the information, techniques and methods discussed in the lectures, to the analysis of important topics in electrical energy systems.
* Critically evaluate a power network, and make observations relating to it's applicability to a particular application, or proposed modifications to the network.
Content: * Energy and power; forms of energy; energy conversion from energy sources including wind, solar, tidal, bio-fuel, wave, hydro, nuclear and fossil fuel.
* Structure of a modern power system: operating charts, voltage control, matrix representation of transmission lines. Two port network representation of transmission lines, per unit system, fault analysis: symmetrical components.
* Transformers: their construction, operation, connections, relevant calculations.
* Load flow analysis: network matrix representation, Gauss-Seidel and Newton-Raphson solution techniques. AC/DC conversion: converter types, dc transmission, advantages compared to AC transmission. Overvoltages: switching and fault overvoltages, Bewley Lattice diagrams, switchgear principles, current chopping, insulation coordination. Modal component theory: wave propagation.
