Synchronous machine power system analysis free lecture pdf
1.It is used in power houses and sub-stations in parallel to the bus bars to improve power factor. For this purpose it is run without mechanical load on it and over excited. 2. In factories having large number of induction motors or transformers operating at lagging power factor, it is used for improving power factor.
3. It is used to generate electric power at power station, one of the most important applications of synchronous machines.
