DSP drives speed and accuracy; coherence saves the day - DSP techniques lead to faster, less costly frequency-response tests and enable the use of a powerful concept, the coherence function, which acts as a watchdog to help identify and quantify common but easy-to-miss measurement errors. Best of all, this watchdog works for free.

By varying the alternator fields, the terminal voltages are brought up to the rated values(V). The speeds of the sets are adjusted by means of the motor [ ]. Synchronous generators or alternators are synchronous machines used to convert mechanical power to ac electric power.

Armature Reaction Reactance - Synchronous Generators

Nowadays, an isolated synchronous generator supplying its own load independently of other generators is very rare. Synchronous machines are commonly used as generators especially for large power systems, such as turbine generators and hydroelectric generators in the grid power supply.

Because the rotor speed is proportional to the frequency of excitation, synchronous motors can be used in situations where constant speed drive is required.
