The course starts by reviewing current practice to establish a sound understanding of the underlying principles of power system transmission, distribution, operation and control. Next are considered the developments that are taking place as a result of new forms of generation, load interconnection, fault level limitation and numerous advances in system innovation. The manner in which the new technologies are implemented is related to geographical location, sites requiring additional power, government strategy and technical motivation for change. Not all power systems will advance at the same rate, but all will take advantage of the benefits of technology to a greater or lesser extent, thus improving the overall electrical efficiency.
The course aims to make candidates aware of improvements that technological advances makes possible and to consider implementation these on their system, whether it be a utility, a large end user, or an industrial islanded system. Asset management, DSM, non linear loads, harmonics and on line diagnostics of plant are also considered, as are ways of improving the utilization and efficiency of system plant.
Upon Completion of this Course, participants will have knowledge about :
The operation and power flow characteristics of small large networks and how the network can be arranged to deliver more real power over the transmission system to the load centers
The form and use of a range of FACTS devices to improve system operation
Fault level limiting devices
New CT and VT optical transducers and protection relaying system using microprocessor configured relays
To deal with non-linear loads and the problem of Harmonics, at the PCC (point of common coupling)
