Which term describes the necessary synchronization between a facility's generator and the utility's power supply?

The term that describes the necessary synchronization between a facility's generator and the utility's power supply is frequency matching. When a generator is brought online to supply power alongside an existing utility source, it must operate at the same frequency as the utility grid. In most regions, this frequency is typically 60 Hz.

Frequency matching ensures that the electrical energy produced by the generator is coherent with the grid. If the generator operates at a different frequency, it can cause issues such as back-feeding into the grid, leading to equipment damage or power quality problems.

Proper synchronization involves adjusting the generator's speed to match the frequency of the grid, allowing a seamless integration of power sources. This is crucial for maintaining stability in the electrical system and ensuring efficient operation. Matching the frequency also encompasses aligning voltage and phase angle, although the primary focus here is the frequency itself.

In summary, frequency matching is essential for ensuring that both power sources operate harmoniously within the electrical system, promoting safety and reliability in power supply.
