WIND MONITORING


MAXIMISING THE VALUE OF WIND MEASUREMENT EQUIPMENT


Prevailing is a resource assessment consultancy providing a wide range of high quality technical services to the wind industry worldwide. The Prevailing Wind Data Management Service helps clients maximise the value of wind measurement equipment installed on their site. Monitoring and fault identification leaves them better informed, while preventing delays and costs.


Collection of good quality wind data is a vital step to financing a project. Financial grade energy prediction requires at least a year of on-site wind data collected with a well specified mast. Problems with the monitoring equipment can result in missing or incorrect data.


These issues are common and can range from anemometer failure to a complete mast collapse – identifying these issues early maximises data coverage.


More subtle, but perhaps more significant, are issues which if left undetected, will result in poor quality data. Instruments may remain functional, but close inspection can reveal faults or changes that prevent confident onward use of the data. This lack of confidence translates to higher assessment uncertainty and worse financing terms.


COMMONS ISSUES INCLUDE… • Anemometer or wind vane degradation • Instrument mounting errors • Wiring, logger and charging system faults • Boom shifts or instruments becoming loose on their mountings


• Undocumented maintenance and changes


• Missing or incorrect documentation


Failure to detect these faults during the monitoring phase can result in a need to extend or repeat the measurement campaign, causing major delays to the project.


TRAINED AND RESPONSIVE TEAM Prevailing ensures that all monitored masts are checked daily by an attentive and responsive team of wind analysts. All staff are fully trained in financial grade analysis, able to advise with confidence on any detected faults, and work with maintenance contractors to ensure rapid resolution.


PRIORITISATION AND DECISION MAKING Alongside accurate and secure data collection, a good wind data management service will also provide project prioritisation and decision making tools. Continuously updated analysis results such as long-term correlation provide an early indication of wind farm performance, long before a year of data is available.


Confidence in this prediction increases gradually as the data set grows, providing an accurate input for financial modelling before a formal assessment is completed. The Prevailing Wind Data Management Service provides automatic long-term resource estimates each week, for a fast and efficient route to project finance.
