| Description:
| Aims: To provide a detailed understanding of the basic concepts involved in the simulation and analysis of power systems networks. Learning Outcomes: Define the transmission line propagation constant and its characteristic impedance; demonstrate a clear understanding of some of the fundamental problems of power transfer over long distance ac transmission lines; explain power flow equations using Gaussian and Newtonian methods; understand the difference between stability of single machine and multi-machines within a large power system network. Skills: Application of the information, techniques and methods detailed in the unit material, to the proposal of, and the carrying through of, appropriate solutions to engineering problems in the simulation and analysis of electrical power systems. Taught, facilitated and tested. Content: Transmission system simulation: Transmission line model; interpretation of the equations; hyperbolic form of the line equation; simple transient analysis; Long line transmission: Steady-state operation; operation under fault conditions; line protection problems associated with compensated lines. Linear and non-linear a.c. power flow solutions: Computer aided analysis; the bus admittance matrix; survey of the different power flow techniques; types of buses in a power system; accounting for transformer tap changers and phase angle shifts. Symmetrical short-circuit analysis for large systems: Tools for power systems network reduction and computer analyses; Korn's formula for the solution of large networks; matrix inversion through factorisation; simulation of disturbances in power system analysis; analysis of three-phase short circuits for circuit breaker rating evaluation. Challenges to ensuring transient stability in large power systems: Stability of a synchronous generator/machine connected to an infinite busbar; process of studying multi-machine power system stability; the electric centre of a power system; the effect of different fault types on transient stability; computer analysis of transient stability of large power systems. |
