Introduction

Interpretation of the core content of the standard

Technical modules	Key indicators	Innovation points
Tower structure	Verticality ≤1/1000, resistant to wind load once in 30 years	Gusted truss structure design
Sensor configuration	Wind speed measurement range 0-90m/s, resolution 0.1m/s	Optional heating function in icing areas
Data acquisition	1 second sampling frequency, MTBF≥3000 hours	Sliding calculation of maximum wind speed algorithm

Key technical requirements of sensors

The standard stipulates that three-cup wind speed sensor and single-wing wind direction sensor are basic configurations, and strong wind meter (0-90m/s) is required in typhoon-affected areas. Platinum resistance sensor is used for temperature measurement with an accuracy of ±0.2℃.

Data quality control system

Three-level quality control code is used:
0-correct data | 1-doubtful data | 2-wrong data
Example: When the wind speed value exceeds 60m/s (90m/s for strong wind instrument), it is automatically marked as 2

Environmental adaptability design

The equipment must pass:
• -50℃~+50℃ temperature test
• 48-hour salt spray test (GB/T 2423.17)
• Level III mechanical vibration test

Implementation suggestions

Dual wind speed sensor redundancy is configured at the hub height
The solar power supply system needs to ensure 15 days of battery life
Data files are named in the format of WT_L01_IIIii_YYYYMMDDHH.BIN
