the operation of connecting an alternator with other alternator or with common bus-bars is known as synchronizing.Generally alternator used in power system where they are connected in parallel with other alternator.
condition for parallel operation of an alternator
1. The terminal voltage of incoming alternator must be same as the bus-bars voltage.
2. The speed of incoming alternator must be such that its frequency f =pn/120 as the same frequency of the bus-bars.
3. The voltage of incoming alternator and the bus-bars voltage are in same phage.
Motor, Generator
When two generators are to be run in parallel, one generator is first started and some load is given. Then second generator is brought in parallel with the running generator (subject few conditions, like voltage, frequency, phase angle). First generator which is running is known as running generator, the second generator which gets connected is known as incoming generator
a motor drives something a generator is driven by something
In the operation of a standard generator, the exciter rotor and stator provide DC-type energy to an AC-type supply. This allows the exciter to maintain a constant DC source.
Transformers can be connected in parallel, if they have the same primary and secondary voltages and equal operating frequency.
Motor, Generator
there will be circulating current between the generators sufficiently large that might damage the machines.
CONDITIONS REQUIRED FOR TRANSFORMER PARALLEL operation are.. 1. Voltage turn ratio. 2. phase sequence 3. Impedence should be same 4. polarity Hitesh

The generators also have resistance which causes power loss and voltage drops. Connecting them in parallel reduces the total resistance that reducing the voltage drop as well as increasing the total current.
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.

The generator circuit breaker or gcb is a circuit breaker which is connected with the generator . Whenever there is a fault in the generator the circuit breaker trips and disconnects the generator from operation thus it helps the place from a serious accident etc..
In a grid system all the alternators run in parallel, locked together in frequency.
Because millman's is used in parallel ckt of impedances and voltage sources
In generator parallel operation, isochronous refers to a mode where the generators share load equally by maintaining a constant speed regardless of load variations. Droop, on the other hand, is a control method where generators deviate slightly from each other in speed to allow load sharing based on the proportion of setpoints or power output.
