Synchronous alternators are the main machines used for the generation of electrical energy. They are intended to supply electrical power to the final loads through transmission and distribution systems. Besides, without going into technical details, by acting on the excitation of alternators, it is possible to vary the value of the generated voltage and consequently to regulate the injections of reactive power into the network, so that the voltage profiles of the system can be improved and the losses due to Joule effect along the lines can be reduced.<\/span><\/p>\n<\/div>\n
They are synchronous motors running no-load in synchronism with the network and having the only function to absorb the reactive power in excess (under excited operation) or to supply the missing one (overexcited operation).<\/span><\/p>\n
