Basler — Parallel Operation Sequence
Operation · Generator sets
From a Basler service manual — check it applies to your exact model before use.
Procedure
- Start generator set No. 1.
- Close circuit breaker connecting it to the bus.
- Adjust its voltage and frequency to nominal.
- Apply load (10% or more of kW rating if possible).
- Start generator set No. 2.
- Adjust its voltage to nominal.
- Adjust its speed slightly higher than No. 1's.
- Observing synchroscope, close circuit breaker No. 2 when in phase.
- Verify ammeter reading for set No. 2 is within rating.
- Adjust speed of No. 2 for desired kW share.
- Adjust voltage of No. 2 until ammeter readings of both sets are near minimum.
- If KVAR or power factor meters available, adjust voltage adjust rheostat for equal/proportional readings.
- With full load applied, readjust speed and voltage on No. 2 until desired load division obtained.
Specs & values
- Paralleling should be attempted only when speeds (frequencies) are equal and generator voltages are equal and in phase
