DEIF FAS-115DG Synchronisation & circuit breaker closing

FAS-115DG

Synchronisation & circuit breaker closing

DEIF's synchronisers are applied for synchronisation of a generator to the busbar and closing of its circuit breaker when the voltage difference, the slip frequency and the phase angles are within the preset limits.

DEIF's synchronisers are applied for synchronisation of a generator to the busbar and closing of its circuit breaker when the voltage difference, the slip frequency and the phase  angles are within the preset limits.

The synchronisers can be applied in conjunction with a wide range of prime movers, as its control pulses may be set to fit several types – from slow reacting dieselengines to fast reacting gas turbines.

The LSU-112DG is equipped with an unload input.

When activated this input will control the power unit to

zero power, and at the same time the power output of

the LSU-112DG is disconnected from the paralleling

line.

The calibration of the LSU-112DG is done so it matches

its power unit. This means that load sharing between

power units with different size will be performed accord

ing to the actual size of the individual power unit in the

plant. For example a 100 kW PU and a 150 kW PU

running in parallel will share a total load of 125 kW into

50 kW and 75k W. If the 150 kW PU is derated to 100

kW by means of the DERATING potentiometer on the

front of the LSU-112DG, the load in the above example

will then be shared equally between the two power

units.
