Aims: To provide students with an insight into, and an understanding of, analytic methods applied to power system analysis.
Learning Outcomes:
After completing this unit, students should 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 and demonstrate an understanding of the use of dc transmission worldwide; conduct a simple stability study and explain the influence of AVR and governor types on system stability; analyse transients on power systems caused by switching operations or faults for both single and multi-phase situations, and hence be able to specify insulation requirements.
Skills:
Application of the information, techniques and methods discussed in the lectures, to the analysis of important topics in power systems. Taught, facilitated and tested.
Content:
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. Basic stability considerations: machine inertia, equal area criterion, effect of AVRs and governors. Overvoltages: switching and fault overvoltages, Bewley Lattice diagrams, switchgear principles, current chopping, insulation coordination. Modal component theory: wave propogation in multiphase networks.
