FICTIONAL SAMPLE - Contoso Renewables, Quellmoor Ridge Wind Farm and every organisation, person, product and value in this wiki are invented. Not for operational use.

WTG-09 is a wind turbine at Quellmoor Ridge Wind Farm.^{123456789101112} Its gearbox oil conversion to PWG 220 is pending under SB-LWS-2025-07, and the completed gearbox oil conversion work order WO-25-0309 is recorded separately.¹³¹⁴ In 2026, WTG-09 had a generator brush replacement work order completed and a leading-edge erosion finding on blade C.¹⁵¹⁶

Facts

• On 2025-01-21 at -24.6 °C, WTG-02 and WTG-09 needed more than 6 hours of heating before starting.¹⁷
• Finding F-04 is category 3 leading-edge erosion on WTG-09 blade C, with erosion between radius 50 m and 57 m, exposed laminate over 0.3 m, and a required leading-edge repair within 6 months.¹⁵
• WTG-09 has gearbox oil conversion to PWG 220 pending and deferred under SB-LWS-2025-07.¹³
• On 2026-04-01, icing alarms A7001 led to S600 Stopped - icing status starts for WTG-12, WTG-09, WTG-03, and WTG-02, with later clears and S600 ends recorded for each turbine in this part.^{1819202122232425}
• On 2026-04-02, WTG-08 and WTG-09 raised A2120 Gearbox oil pressure low at 0.59 bar and later cleared at 1.35 bar.^26272829
• WTG-09 had A3210 Generator brush wear limit reached raised on 2026-07-16 and cleared on 2026-07-18; WTG-09 was also in S310 Maintenance mode on 2026-07-18 from 07:58:12 to 11:52:40.^30313233
• The movements sheet records a 2026-07-18 issue of quantity -1 for LWS-P-51207 against WO-26-0436 for WTG-09.³⁴
• The WTG-09 gearbox oil conversion work order WO-25-0309 was deferred because the access road was closed by snow on 2025-11-24 and was completed on 2026-01-20.¹⁴
• WO-26-0436 for WTG-09 replaced generator brushes for A3210, was completed under WI-GEN-014, used part LWS-P-51207 quantity 1, and notes the shortest brush was 16 mm.¹⁶
• WTG-09 in 2026-01 recorded availability_pct 96.1, energy_mwh 955.9, downtime_h 29.0, and alarm_count 15.³⁵
• The turbine labels shown on the plan are WTG-01, WTG-02, WTG-03, WTG-04, WTG-05, WTG-06, WTG-07, WTG-08, WTG-09, WTG-10, WTG-11, and WTG-12.^{123456789101112}
• WTG-09 had its generator brushes replaced under work order WO-26-0436 following alarm A3210 from 16/07.³⁶
• For WTG-09, the shortest measured brush was B3 at 16 mm, below the 18 mm threshold in WI-GEN-014.³⁶
• For WTG-09, a complete LWS-P-51207 set was replaced and the brush-holder screws were tightened to 12 N·m.³⁶
• WTG-09 was put through run-in at 50 % power for 8 hours, until 20:00 that evening.³⁶
• The next team was asked to check the end of the WTG-09 run-in at 20:00 and return it to 100 % power.³⁷
• PWG 220 conversion status was: nine turbines completed, WTG-11 being converted that day, WTG-12 scheduled for the following Wednesday, and WTG-09 planned for the twenty-fourth if the access road remained open.³⁸³⁹
• From minus twenty, heaters need about four hours to bring the sump to plus five; the previous January, WTG-02 and WTG-09 needed more than six hours.⁴⁰
• If WTG-09 still has PWG 320 in January, its start temperature remains plus ten until conversion is complete; the parameter is changed only with the new oil.⁴¹
