2.
Check of engine primary control functions
Designation
Description
Engine start command (Local)
Engine is started from Local panel. Engine can only start when the start block function is not active.
Engine stop command (Local)
Engine is stopped from Local panel. Only if local/remote switch is in local
Engine start command (CFC061)
Engine is started from CFC061 panel. Engine can only start when the start block function is not active.
Engine stop command (CFC061)
Engine is stopped from CFC061 panel. Only if local/remote switch is in remote
Engine start command (WOIS)
Engine is started from WOIS system. Engine can only start when the start block function is not active.
Engine stop command (WOIS)
Engine is started to its nominal speed and given stop command from WOIS system.
Engine speed increase / decrease commands
Engine speed can be controlled when genset control is selected manual and operation mode is speed droop. (engine not synchronized).
Excitation increase / decrease commands
Generator excitation can be varied when genset control mode is selected manual and generator control in voltage droop control.
Breaker close command against dead bus
Voltage sensing circuit is tested by simulating the conditions when breaker should not close. Closing only possible against dead busbar.
Checked (ok?)
3.
Testing of hardwired shut down functions with running engine
Designation
Description
Emergency stop, CFA901
Emergency push button (plant shut down) activated in common control panel CFA901
Emergency stop, CFC0_1
Emergency push button activated in engine wise control panel CFC0_1.
Emergency stop, CFE0_1
Emergency push button activated in engine wise control panel CFE0_1.
Lube oil pressure line towards to pressure Lubeoil pressure low shut down switch PSZ201 is closed and vented to function simulate low pressure. Also PT201 PLC HT Water temperature high shut down function
HT water temperature sensor TE402 or TE403 heated over 105°C to activate the shut down function. PLC
PLC initiated shut down function
One shut down function executed in PLC is simulated in order to check the functionality of the shut down circuit with running engine.
Auto shutdown
Engine shutdowns automatically if breaker has tripped and after 2 min running in idle
Oil mist shutdown
Test to blow smoke in to the test opening on oil mist detector
HT water pressure shutdown
Increase the HT water pressure, PLC
LT water pressure shutdown
Increase the LT water pressure, PLC
Exhaust gas temperature
PLC initiated shut down function
Main bearing temperature
PLC initiated shut down function
Cylinder liner temperature
PLC initiated shut down function
Generator winding temperature
PLC initiated shut down function
Generator bearing temperature
PLC initiated shut down function
Checked (ok?)
4.
Engine overspeed protection
Designation
Description
Overspeed protection, engine speed control system
Engine speed is raised to reach engine over speed limit, or trip limit is reduced to simulate overspeed trip. Limit is set in the software.
Mechanical overspeed protection
Engine’s speed is raised until the mechanical over speed limit is reached. (if applicable)
5.
Over speed setting
Measured maximum speed
575rpm
Test of engine’s synchronization functions
Designation
Description
Manual synchronization
Engine frequency and voltage level can be controlled on the engine to be synchronized on the busbar. Breaker closed manually on the sync unit.
Automated synchronization
Engine frequency and voltage controlled by auto synchronizer. Breaker closed automatically.
