9.1 DSE 4 STEPS TO SUCCESSFUL SYNCHRONISING
NOTE: The DSE 4 Steps must be followed before any parallel operation is attempted. The
full video presentation of the 4 Steps is available on the DSE website: www.deepseaplc.com
This page is also available as a DSE Training Document, refer to DSE Publication: 056-001
Four Steps to Synchronising.
The following information is a
short form guide only, intended as a memory jogger once the steps are
fully understood.
9.1.1 CONTROL
NOTE: Failure of these steps results in poor control of the governor and AVR leading to
problems during synchronising and load sharing if not corrected.
Check the control from DSE8x10 is working:
•
Control of AVR
• Control of Governor
•
Direction of Control
9.1.2 METERING
NOTE: Failure of these steps results in incorrect power factor and kW calculations
leading to problems load sharing if not corrected.
Check the metering on the DSE8661 and DSE8x10 is working:
•
CTs on the Right Phase
• CTs in the Right Direction
9.1.3 COMMUNICATIONS
NOTE: Failure of these steps results in the controllers being unable to communicate
leading to problems during synchronising and load sharing if not corrected.
Check the MSC link connected to the DSE8661 and DSE8x10 is working:
•
All Modules Connected on the MSC Link
•
Re-Calibrate, Sync + Load Control, Multi-Set
•
Remove One MSC Plug
9.1.4 SYNC CHECKS
NOTE: Failure of these steps results in serious damage to the system (breakers, bus
bars, alternators, engines etc)
Check each phase across the breakers controlled by the DSE8661 and DSE8x10 modules are wired
correctly:
•
Use the Built in Sync Scope to Determine Correct Phase Wiring
•
Phase Checks across the Breaker.
