This unit will analyse electricity distribution in the deregulated Australian power industry to critically examine the planning, design and operation of electrical transmission and distribution networks. Network calculations and the bus-admittance matrix will be covered. The concept of load flow analysis and its use in network planning and analysis will be explored. Contemporary approaches including Gauss-Seidel, Newton-Raphson, and Fast Decoupled load flow analysis methods and their application to the solution of complex networks will demonstrate alternative and complementary strategies in the operation, design and planning of electrical distribution and transmission networks. The subject addresses electrical insulation properties and characteristics, insulator selection and co-ordination in electric energy networks. Sources of overvoltages, lightning impact on transmission and distribution networks, surge propagation theory, circuit interruption theory and circuit breaker operation are investigated as enduring challenges to be addressed through networks. The unit also considers the impact of breakdown in gases, liquids and solids on the provision of reliable electrical insulation in electrical networks.
