Training Course
Advanced DLE Training
Course Introduction
A 5 day specialised course focused on DLE gas turbines, covering DLE theory, control operations and schedules, special controls aspects, and a workshop for root cause analysis and complex troubleshooting using a unique training simulator.
The course can be tailored to the control variant installed at your site and to the specific LM engine model in operation.
Course Agenda
Day 1
- Module 1 — Compressor Control: transient operability control, variable geometry of the compressors, variable geometry schedules, instrumentation schedules, associated ALM/DM/STI/SD
- Module 2 — DLE Combustor Control: DLE principles & combustor, combustion dynamics, DLE fuel system, combustor instrumentation loops, flame temp control / bleed / windowing, Tflame algorithm, bleed schedules, staging control
Day 2
- Module 3 — Turbine Control: turbine sensors & loops, instrumentation schedules, thrust balance control, associated ALM/DM/STI/SD
- Module 4 — Fuel Flow Control: control requirements & critical inputs, regulators/limiters, fuel control GAP structure, typical baseload Tflame to fuel flow, ring fuel flow demands, FMV control from core, GP sensors, ring fuel nozzle scalars, LHV/SG
Day 3
- Module 5 — Control Operations: BRNUL upper limit, ABC to AB stage down, pilot Tflame alarm, acoustic protection, E-ABAL, stall detection, flame detection, start to core idle, grid/droop & isoch operation, start–stop
Day 4
- Module 6 — DLE Mapping: fundamentals (what, how, why, when), operating modes, window boundaries, ring flame distribution, blowout detection, problem signatures & exercises, control schedules, mapping output, operational corrections, combustor operability map
Day 5
- Module 7 — Workshop (DLE Troubleshooting Class): covers ~10 real live operational problems; students learn to find root cause and correct using datalogs, alarm lists and training materials; cases include start-up, acoustic, stage-down, flame out and stall events; supervised by an experienced trainer
