Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
PO034: Assessment of the suitability of diverse precipitation measurement technologies for deployment on wind energy converters in the context of species protection
Hannah Sylvester, Senior Project Engineer, WRD Wobben Research and Development GmbH
Abstract
Wind energy converters (WEC) can optionally be equipped with precipitation measurement devices to improve curtailment strategies for bat and bird protection by adding precipitation as an additional meteorological parameter, alongside wind speed and temperature, and thereby reducing energy losses without compromising species safety. As ENERCON has no precipitation sensor on the current product portfolio, the opportunity to identify a measurement device which fulfills the demand from operators as well as regulatory requirements regarding measurement accuracy and reliability was given. Therefore, a one-year field measurement campaign on different precipitation sensors was initiated. The measurement campaign was conducted to support a data-based and field-relevant sensor selection process, followed by validated operational integration to product portfolio in case of promising results. First, relevant influencing variables were identified in consultation with internal and external stakeholders (sensitivity analysis). Afterwards, the measurement setup was fixed. It consisted of five sensors representing different measurement technologies plus an identical ground-based reference setup to validate the measurements on nacelle-level and identify the influence of the WEC. The evaluation was carried out by two methods: analyzing evaluation metrics and using a comparative approach. As a result, all precipitation sensors on nacelle can represent the ground measured precipitation values interpreted by the evaluation metrics. When directly comparing the data from nacelle and ground measurement, deviations in performance quality among the examined sensors were observed. Regression analyses show that the measurement data of the laser-beam technology using Laser-Precipitation-Monitor (LPM) exhibit the highest coefficient of determination, when comparing ground and nacelle values. The LPM was therefore defined as the most resistant to disturbances on a WEC regarding the influencing variables discussed on the sensitivity analysis and therefore the best choice to apply on a WEC.
