HYBRICON PCI354-1022-38 02088-019 module

The first two conditions are determined when the equipment is specified, installed, and wired. The synchronizer matches the remaining conditions (voltage, frequency, and phase) before the paralleling breakers are closed. Functional Description This section describes how generator and bus matching occurs and how all conditions are verified by the synchronizer functions.NOTE In systems that operate in parallel with the mains, or with loss of mains detection modes, it is recommended that each EGCP-2 unit in that system receive the Mains and Bus PT inputs for proper operation.

Synchronizer Description 

Synchronization, as normally applied to the generation of electricity, is the matching of the output voltage waveform of one alternating current electrical generator with the voltage waveform of another alternating current electrical system. For the two systems to be synchronized and connected in parallel, five conditions must be considered: 

• the number of phases in each system

 • the direction of rotation of the phases 

• the voltage amplitudes of the two systems 

• the frequencies of the two systems 

• the phase angle of the voltage of the two systems

Operating Modes

The EGCP-2 control is capable of synchronizing across both the generator and mains breakers, depending on the application of the generator set, and the configuration of the EGCP-2. An EGCP-2 configured for No Parallel operation will never allow the generator and mains breakers to be closed at the same time, and therefore does not synchronize across the mains breaker. Units configured for Mains Parallel operation will actively synchronize the generator, or in the case of a multiple unit system, generators, to the utility before closing the utility tie breaker.
