Synchronization

IntroductionThe easYgen-3200 is able to perform synchronization of the generator

across the generator circuit breaker to a common bus as well as

synchronizing the common bus to a utility across the mains circuit

breaker. It is possible to configure the easYgen-3200 for either slip or

phase matching synchronization and the acceptable breaker closurewindow.

By adding SPM-D/10 synchronizers to the system, up to four generator

common busses and three tie breakers may be operated.

Used to calculate when breaker close pulse is issued

Formula for calculating phase angle at closing command

Phase angle = 360o* (Frequency differential) * (breaker closing time)

Example:

Phase angle = 360o* (0.3 Hz) * (0.2 sec) = 21.6

RUN Active synchronization is performed. Bias signals to the

governor and voltage regulator are active and breakerclose commands are issued.

PERMISSIVE Passive synchronization performed. Bias signals to the

governor and voltage regulator are not active but breakerclose commands are issued.

CHECK Active synchronization is simulated. Bias signals to the

governor and voltage regulator are active but breakerclose commands are not issued.

OFF The synchronization can be disabled

Configure the following application:

1. You are commissioning an emergency standby generator for a manufacturing

plant. Select a breaker logic for the test run where the generator assumes the

entire plant load and then separates from the utility. The test mode must be

initiated via a discrete input.

2. A second breaker logic mode is desired where the generator assumes the

entire plant load but still remains paralleled with the utility.
