Necessary condition for parallel operation of two alternators:
- The phase sequence of the busbar voltages and the incoming machine voltage must be the same
- The busbar voltages and the incoming machine terminal voltage must be in phase.
- The terminal voltage of the incoming machine and the alternator which is to be connected in parallel or with the Busbar voltage should be equal.
- The frequency of the generated voltage of the incoming machine and the frequency of the voltage of the busbar should be equal.
- The phase difference between the alternator and infinite voltages must be zero.

Voltage, Frequency, and Phase Sequence Matching
In order to connect an alternator to an infinite bus, it is crucial that the alternator and the infinite bus have several key parameters matching. These parameters include voltage, frequency, and phase sequence.
Voltage Matching
The voltage of the alternator must be the same as the voltage of the infinite bus in order to ensure a smooth transfer of power. If there is a mismatch in voltage levels, it can lead to issues such as voltage instability and equipment damage.
Frequency Matching
The frequency of the alternator must also match the frequency of the infinite bus. This is important for ensuring synchronization between the two systems. If the frequencies do not match, it can lead to power quality issues and instability in the system.
Phase Sequence Matching
In addition to voltage and frequency matching, the phase sequence of the alternator must also match the phase sequence of the infinite bus. This means that the phase difference between the alternator and infinite bus voltages must be zero. If there is a phase sequence mismatch, it can lead to issues such as reverse power flow and system instability.
In conclusion, in order to connect an alternator to an infinite bus, it is essential that the voltage, frequency, and phase sequence of the alternator match those of the infinite bus. This ensures a seamless and stable operation of the combined system.
