Starting Large Motors on board ships

• Typical starting methods
• Direct On Line (DOL)
• Star-Delta
• Autotransformer (ATS)
• Electronic Soft Starters
• Electronic Frequency Drives (VFD)
• What is the optimum starting method for marine
  application ?

7
Direct On Line Starting (DOL)
Direct On Line Starting results in High Inrush
Current Mechanical Shock

• The high inrush current can result in voltage
  drops
• The high mechanical shock can result in damage to
  the motor, load and transmission system (gear,
  belt, etc.). It can also require frequent
  maintenance.

8
Star-Delta Starting
Two steps starting Y connected (58 Un),
transfer to Delta (100 Un)

• Transfer to Delta by timer - open loop control,
  which may result in very high inrush current if
  transfer is done before motor reached close to
  full speed
• Step angle of 30

9
Autotransformer Starting (ATS)
The inrush current of the transformer in an
Auto-transformer starter may be too quick for the
EVR to respond, resulting in a voltage drop

28
Easy Operation

• Easy adjustments for all applications, matching
  motor - load characteristics

29
When To Use Soft Starters

• Summary
• When starting current must be reduced to avoid
  voltage drops, due to the low ratio between motor
  / Generator power.
• When starting torque must be reduced (mechanical
  problems)
• When starting complicated mechanical loads
• When starting sensitive loads
• When starting high inertia loads (long starting
  time)
• For frequent starting
• Preventing over pressure and hammer effect in
  pump applications
