- How to Check Wind-Farm Grid-Code Compliance in China: the Three Layers (the Technical Standards GB/T 19963.1-2021 Onshore and 19963.2-2024 Offshore, the Turbine Test Standards IEC 61400-21-1:2019 and GB/T 36995-2018, and the Regional 'Two Rules' That Assess Day to Day), What Must Be Proven and When (Southern Region 2025: Transient Models and a Validation Report Three Months Before Connection; Power Quality, AGC, AVC, Primary Frequency and Inertia, Model Evaluation, Ride-Through Simulation and SVG Ride-Through Verification Within Six Months, by a Qualified Test Unit; Grid-Connection Testing Again Above 40 MW of Added Capacity), the Numbers the Dispatcher Watches (AGC Response Under 2 Minutes, 35%/min Ramp, 3% Accuracy, 99.9% and 99% Thresholds; Dynamic Reactive Availability 95%, AVC 98%; Primary Frequency Assessed on Commissioning Only at This Stage, Capped at 1.5 h, While Article 33 Still Requires Performance to Standard) and How the International Frameworks Compare (IEC 61400-27-1 Generic Models, IEEE 2800 IBR Requirements)
- How to Check Wind Turbine Gearbox Condition Monitoring: the Design Frame (IEC 61400-4:2012 for Gearboxes Above 500 kW, Rolling-Element Bearings, Lubrication and Prototype Testing — Withdrawn 15 April 2025 in Favour of IEC 61400-4:2025), the Vibration Standards (ISO 10816-21:2015 for Geared Turbines Above 200 kW — Now Withdrawn in Favour of ISO 20816-21:2025; China's NB/T 31004-2011, Current Since November 2011), Why the Gearbox Is the Component to Monitor (Longest Downtime per Failure in ~15,400 Turbine-Years; 0.154 Major Replacements per Turbine-Year Offshore, 95% of Major Replacements With the Generator; Not Always Meeting 20-Year Design Life), What Fails (36 of 37 Incidents in One Small Database Involved Bearings — Hardening Cracks, Abrasion, Scuffing) and How Good Vibration Diagnosis Was in One Blind Test (NREL's Round Robin: Best of Sixteen Partners Found Five of Seven Damages; Most Had More Misses Than False Alarms; One Partner Found Six of Seven in Hindsight)
- How to Check Wind Turbine Yaw and Pitch Systems: the Design Frame (IEC 61400-1:2019 Covers Control and Protection Functions; GB/T 18451.1-2022 Adopts It Identically), the Chinese Product Standards (GB/T 32077-2025 Pitch Systems, Effective 1 November 2025, Replacing the 2015 Edition; GB/T 47560-2026 Yaw Systems, Effective 1 August 2026) and O&M References (GB/T 25385-2019; DL/T 666 and 797-2012; NB/T 31004-2011), the Failure Evidence (Carroll et al.: Pitch/Hydraulic Is the Largest Share of Offshore Failures at ~13%, 0.824 Minor Repairs per Turbine-Year, with Oil and Valve Issues ~30% of Them; Yaw at 0.162 Minor Repairs), and the Yaw-Alignment Evidence (NREL: Vane Errors from Rotor Wake, Nacelle Flow and Calibration; a 7.5° Offset Correction Estimated to Add 2.4% AEP; Deliberate Offsets for Wake Steering Measured at +4% for a Pair)
- How to Check Wind Farm Wake Effects: How Large They Are (Wake Is One of the Largest Energy Losses; a 15–40% Figure the Review's Discussion Calls Wake AEP Loss While Its Fig. 9 Is Labelled an Uncertainty Plot; Estimated Wake Loss Exceeds All Other Predicted Losses Combined; a Predicted Energy-Uncertainty Range From Wake of About 6%), Why They Are Under-Estimated (Ørsted 2019: Blockage and Wake Under-Forecast Across Its Portfolio, Likely Industry-Wide; External Wake 'a Bigger Known Unknown'), How Neighbours Change the Answer (Danish Waters: 9–11% Wake Loss as Built in 2021, 19–21% in the 2030 Scenario), What a Chinese Micrositing Case Shows (28-Turbine Offshore Layout: 10.58% Average and 15.58% Maximum Single-Turbine Wake Loss Against the NB/T 10103-2018 Guidance of Below 8% and Within 15%, as Quoted in the Project Report) and Which Models and Controls Exist (the Gauss-Curl Hybrid Model's Documented Deep-Array and Long-Distance Discrepancies and the Cumulative-Curl Model Offered to Fix Them; Wake Steering's Measured 14% Downstream and 4% Pair Gain Over a 10° Sector)
