TROUBLESHOOTING FAULTS:
Control and protection
Power failures in the generator and associated equipment, motors, switches, motor control center, relays, plugs, transformers, faulty synchronization
Mechanical failures in turbine components such as fuel nozzles, combustors baskets, transition pieces, vanes, nozzles, etc
Instrumentation failures in thermocouples, pressure transducers and transmitters, pressure switches, temperature switches and flame detectors
Failures in auxiliaries systems components, such as starting motor, lubricating oil, hydraulic oil, cooling water system, fuel gas system, fuel oil system
Troubleshooting of electrical, mechanical, instrumentation and control failures
Study of logical sequences for startup and operation
ACTIVITIES
Logical analysis of sequences that control the different processes during a start as: turning gear cycles, clutch, start permissives, starting and stopping of the engine lube oil pumps, ignition sequence, flame detection, acceleration to complete sequence, inlet guide vanes control and bleed valves control
Synchronism check for closing the generator breaker.
Active (MW) and reactive (MVAR) power loading. Evaluation of generator parameters
Operational evaluation of turbo generating units
ACTIVITIES
Evaluation of physical and operating parameters of all the devices that constitute each of the auxiliaries systems (lubricating oil, hydraulic oil, cooling water, cooling air, combustion, etc). Issue recommendations to optimize their operation
Identification of components that are not operating efficiently to recommend their replacement in order to improve the operation of the process
Supervise routine maintenances, hot gas path maintenance and major overhauls
ACTIVITIES
