Short History of Wind Measurement in Vietnam
• 2001 - First Wind Energy Resource Atlas of South East Asia
• 2011 - Wind Resource Atlas of Vietnam MOITSponsor: World BankConsultant: AWS Truepower
• High potential along the southern and south-central coasts and in the mountain gaps in central Vietnam
• 3,000 km coast line!
• 6.5 to 7m/s in the central-south coast
Results: Standard error 0.8m/s
Local Measurements needed

Short History of Wind Measurement in Vietnam
• 2011 – First IEC and MEASNET conform Measurements in Vietnam done by the GIZ, World Bank and Government of Vietnam 10 masts at different sites installed by PECC3
• 2019-2015: Different masts in private projects
• 2016 to 2018 – KfW Bank – German funding project20 to 40 masts at different sites
• 2016 to 2018 – World Bank Project6 to 8 masts (to be installed by PECC3)
Final Vietnam Atlas to be done in 2018

International Standard for Wind Power Performance Measurement
Standards + Guidelines
IEC 61400-12-1„Power Performance Testing” (CD2)
Set-up of a met mast including installation of sensors, sensor quality regarding accuracy and reliability
Criteria for data quantity and quality, as well as reporting
NEW IEC coming soon: Quality criteria for SoDAR / LiDAR devices and ultrasonic anemometer for wind assessment /
traceability of measurement data
Ammonit Measurement Systems
MEASNET „Evaluation of site specific winds”
Process of site assessment incl. data collection, evaluation and interpretation
Focus on data quality, plausibility and integrity incl. data filtering and reporting

Betz Law
Wind speed
• Wind energy is proportional to the cube of the wind speed according to Betz’ law:Wind power is
P = 1/2 • ρ • A • v³ Δ1% wind speed ≈ Δ 3% wind energy
• Measure the wind conditions to calculate the wind energy
• A is the area; • ρ is the air density, ρ = p / (R • T), being p the air pressure,
T the air temperature and R the gas constant; • v is the wind speed

Impact of Measurement Errors on Estimated Annual Energy Production (AEP)
Comparison: the impact of different wind sensors on the assessment
• Reduce measurement errors by installing high quality sensors
• Even small discrepancies in the evaluation of wind speed data lead to significant deviations in the assessment calculations
Generated Energy Error by 1% Measurement Error Notes
Anemometer Δ1% wind speed Δ3% energy Most important measurement
Wind vane No direct relation, but eventually wrong wind park design
Important measurement for wake effect
Barometric pressure sensor Δ1% pressure Δ1% energy Extrapolation of pressure
possible once site is known
Temperature Sensor 1°C 0.35%
Humidity Sensor with 40°C; 1% 0.05%

Why high quality measurement equipment?
Leverage Effect: Impact of measurement error on profitability
A small error in the energy assessment has a huge impact in the profitability of a project.

Mast installation
The proper placement of the mast is crucial for a successful wind measurement campaign
Regulation: IEC 61400-12-1:2005
• The standard height of approx. 100m
• The height of the measuring masts are constantly growing
• The mast must have at least 2/3 of the expected height hub
Measurement with remote sensing devices
• SoDAR (Sonic Detection and Ranging)
• LiDAR (Light Detection and Ranging)
• Measurement at hub height in up to 200m
• Complementary to met mast

Different wind profiles
Atypical profile: wind speed decreases after 30m
• Measuring wind speed at the highest height necessary
