The electrical power system consists of three major components: generation, a high voltage transmission grid, and a distribution system. The high voltage transmission system links the generators to substations, which supply power to the user through the distribution system
Modern electrical power systems increases the efficiency of electrical power generations, transmission and distribution it also lower carbon footprint for a greener world. It includes the ‘green generation’ of electricity by means of PV Solar Systems, Wind Power Technology, Geothermal Technology and Hydro Power.
In addition the introduction and merits of the Smart Grids are also discussed in the seminar. The determination and control of fault levels, active power, reactive power, voltage and frequency are essential in a modern electrical power system. Power quality issues are also addressed by modern mitigation techniques.
Power System Stability incorporates the Flexible AC Transmission System (FACTS) have been evolving to a mature technology with high power rating. This technology has wide spread application, became a top rate, most reliable one, based on power electronics. The main purpose of these systems is to supply the network as quickly as possible with inductive or capacitive reactive power that is adapted to its particular requirements, while also improving transmission quality and the efficiency of the power transmission system.
