Compare resource and production records, coordinate equipment-specific service and energy controls, then retain acceptance tests and measured follow-up.
Collect current turbine, tower, controller and storage manuals, service bulletins and the previous inspection record. Identify the responsible qualified service team, access plan and known faults. Set the scope from the actual equipment and condition rather than an assumed generic maintenance interval.
Compare measured wind, energy, availability and metering boundaries across matching periods. Check missing observations, changed exposure, curtailment and operating controls before attributing lower energy to wear. Preserve abnormal noise, vibration or visible damage as service observations requiring the appropriate response.
Use the manufacturer’s service procedure and the site work plan to control electrical, stored and wind-driven mechanical energy. Assign rotor restraint, lowering/climbing, lifting, weather and exclusion-area requirements to the qualified team. A calculator is not an instruction for energizing or exposing equipment.
Have the qualified team inspect the tower, anchors, blades, bearings, wiring, controls and protection as required by the exact manuals and observed condition. Retain measurements, replacement parts and settings. Review the wind diversion path if a control or battery change affects its documented operating envelope.
Record the prescribed post-service inspections and functional tests, accepted configuration and operating conditions. Compare output, threshold behavior, rotor speed and receptor sound only with compatible baseline data. Preserve remaining anomalies and the responsible follow-up actions before accepting normal operation.
Retain the dated work scope, observations, parts, settings, acceptance evidence and unresolved actions. Compare subsequent measured energy with the same resource, meter and availability basis. Use actual condition and the manufacturer’s schedule for future service, preserving portable exports of both calculations and the plan.
Summarize actual energy and downtime-period context for the service request. · Reconcile measured production ratios without treating them as a diagnosis. · Build a comparable post-service measured period record.
Record documented operating regions and observed trips with their controller revision. · Document observed stop/restart regions with the actual control procedure.
Compare resource directions and coverage across observed periods.
Compare documented curve points with suitable measured operating conditions. · Retain matching electrical-curve operating-point comparisons.
Retain measured averaging conditions in the service weather record without deriving a work-at-height limit.
Recheck actual element resistance/heat and controller limits after a documented component change.
Reconcile measured rotor-speed data as a diagnostic record, without assigning a universal optimum.
Reconcile compatible sound-pressure measurements and source/background levels where relevant.
Reconcile the reporting duration and delivered-energy boundary for ongoing monitoring.
Loading your checklist…
Equipment support, inspection and continuing maintenance belong in the project plan.
Power curves and system losses need a comparable resource and measurement basis.
A changed controller, battery or element requires the complete specified operating limits to remain compatible.
Resource and control changes can overwhelm the energy effect of a repair.
Record controller revisions and setpoints so later investigations can identify what changed.
