MAINTENANCE TROUBLESHOOTING COMMISSIONING WIND TURBINE GENERATORS.
To maintain operational all WTG in Wind Farm.
Maneuver Cells and switchgears on Electrical power line.
Galati, Cudalbi is a new build Wind Farm and the task was to put in function all WTG to produce electricity. I was member of team for COMMISSIONING
My main responsibility during commissioning was First Energization-Initial Start-up, which means following operations:
-Check and adjust parameters of protections switchgear type RM6-24KV
-Insulation measurements of transformer, power cable, circuit breakers, generator, circuitry
-Adjust protections-Automatic Breakers, breakers, switches, thermal switches, thermostats
-Check correct tightening torque of cables transformer and outside
-Maneuver Cells Medium Voltage-20KV.
During COMMISSIONING I do following operations:
-Measuring voltage and correctly phase rotation-700V, 400V, 220V, UPC
-Connecting the optical fibers between cabinets
-Transmission of software and communications-PLC software loading, CAN header configuration, touch screen software load
-Wind turbine configuration
-Emergency circuit test-emergency buttons, nacelle emergency circuit test, vibration sensor, smoke sensor, switchgear trip.
-Checking hydraulic system and emergency hub series-measure and adjust pressure in divers points of hydraulic circuitry and check correct reactions of valves, electro valves, solenoid valves, proportional valves, pressure switches, accumulators
-Verify system of orientation of nacelle- sonic anemometer, anemometer/ wind vane, and rotational direction circuitry
-Pith system and hub sensors-pitch position sensor ( BALLUFF ) adjust, blades TC adjustments, check differential filter sensor, leak sensor, adjust lightning transmission sensor
-Checking the beacon system-beacon light
-Checking temperature sensors
-Checking rotation sensors-inductive sensors switch, relay OGS, brake thermistor
-Checking fans and heaters- thermistors, control thermostats, fan circuitry, electrical heaters,
-Checking cooling system-pump cooling circuitry, oil pump cooling circuitry
-Predictive maintenance system PMS-check with software PMS Configuration
-OGS speed and natural tower frequency-relay OGS and use of DAS software for natural tower frequency
Replacement, repair parts and assemblies, electronics, electrical, mechanical, hydraulic
Wind farm is now in production and successfully passed the TEST CAP.
