Alarmas de un aerogenerador

A 90-minute, 4-round basic Express simulation for Spanish vocational training (Formacion Profesional), module 0684 Operacion y mantenimiento de parques eolicos of the Tecnico Superior en Energias Renovables (Real Decreto 385/2011).

The learner is Ziortza Lapuyade, a newly qualified O&M technician of a fictional wind-farm O&M contractor, through 2027, in charge of the twenty-two turbines of a mountain wind farm with one gearbox model.

Four situations set the year's course: the gearbox alarm (bearing temperature and a CMS vibration warning) that keeps coming back on a windy night, and what happens to the turbine (stopped from the SCADA and kept stopped) and how the diagnosis starts (the SCADA trends, the CMS spectra, the oil particle counter and the history read before anyone climbs); the climb to the nacelle before the wind rises, and how it is done (the work permit, the manufacturer's wind limits and the forecast, the rotor locked, two technicians and the rescue kit) and what is inspected (an oil sample, the borescope and the magnetic plug before anything is ordered); the repair in the calm summer window (the bearing replaced up-tower, a crane only if needed) and the fleet (the same gearbox model reviewed on the other turbines); and how the turbine returns to service (the safety chain tested and the run-up supervised before a written hand-back) and how each intervention is recorded.

Three critical errors cap the round: an alarm inhibited and its threshold raised to keep producing, a climb alone with the rotor unlocked, a restart with a bridge in the safety chain. KPIs: technical availability, O&M cost, MWh lost per alarm and risk situations at height. Spanish primary, English parity. Fictional wind farm, company and people; real law (Ley 31/1995) and curriculum cited.

An introductory simulation that assumes no prior knowledge of the subject, designed for undergraduate courses. It also works in vocational and high-school programmes and in onboarding sessions.
