The need for synchronization arises when two or more alternators work together to power the load. Since electrical loads do not remain constant, two or more generators must be connected and run in parallel to supply the power to handle larger loads. Using a series of small units instead of a single generator is known as parallel operation. Parameters such as phase angle, phase sequence and waveform for synchronization and parallelization are matched with a healthy or working power system with Synchronization Control Panels.
