The unit explores two key areas - Power System Supply Chain and Transmission.
Supply Chain: Historical developments and power industry deregulation; Loads and utility ancillary services; Electricity supply basics; Thermal power plants; Other power plants; Alternative energy generation; Distributed generation and energy storage; Rotating machine basics;; Overhead lines and underground cables; Power distribution networks and substation layouts; Auxiliary networks, protection equipment and SCADA.
Transmission: Since transmission lines are the key link between the power plant and customer, it is often considered the most important component of the entire power grid. Consequently, the specialised knowledge in this area is provided from the perspective of operation and planning engineers. Detailed mathematical analysis, modelling and performance evaluation of transmission line is exemplified and contextualised with the power circle diagram. Power transfer through transmission lines are studied and reactive power compensation through traditional and more advanced power electronic devices is explored. Steady-state analysis of transmission lines is performed, and travelling wave phenomenon studied to assess performance of transmission lines. Economic and environmental aspects of transmission lines are also briefly debated in this unit. Transmission line parameters and Ferranti effect will also be explored.
|1.||Discriminate between the elements of the supply chain and how they function in order to map the roles of transmission and distribution systems and auxiliary networks;|
|2.||Contextualise alternative generations such as hydro, wind, solar and other energy systems;|
|3.||Apply principles in the modelling of transmission lines of various lengths with ABCD constants and analyse transmission lines under steady state conditions including power transfers;|
|4.||Illustrate and map transmission line travelling waves and transient conditions in relation to Lattice diagrams; and|
|5.||Assess the use of AC and DC voltages and selection of voltage levels for transmission in wide ranging settings.|
