Aims:
* To develop 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: * Calculate the performance of transformers. * Carry out analyses of symmetrical and asymmetrical fault conditions in electrical energy systems. * Be able to: 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 some ability to think in terms of engineering systems, rather than within the traditional boundaries. To this end students should be able to: * Recognise the principal subsystems of a modern power network. * Recognise and explain the functional purpose of each subsystem. * Application of the information, techniques and methods discussed in the lectures, to the analysis of important topics in electrical energy systems. 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: 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. |
