英文要約itle: Development of New Energy / Research and Development of Offshore Wind Power Generation Technology / Experimental Researches for Offshore Metrological Observation System (Kitakyushu) (FY2009-FY2016) FY2014 Annual Report

A) Establishment of offshore wind observation system, 1. Formulation of meteorological-marine interaction analysis system, 3) Evaluation and verification of meteorological-marine interaction analysis system: Customization of the meteorological-marine interaction analysis system was carried out based on the result of the system calibration using actual data. B) Investigation of meteorological and marine condition, 2. Investigation of meteorological condition, 5) Evaluation of character of wind: Wind shear, turbulence and seasonal variation were evaluated by the measured data more than two-year from October 2012. 6) Evaluation of measurement method: The validity of measured data and the acquisition rate were investigated. The influence of the meteorological tower against wind measurement was evaluated and the wind speed of cup anemometer was corrected. To evaluate the validity of LIDAR, the data measured by LIDAR and the meteorological tower were compared about wind speed and turbulence intensity. 7) Improvement of offshore wind simulation and potential estimation technique: The accuracy of wind simulation by the meteorological-marine interaction analysis system was evaluated by multi-year simulation of the system. 8) Study for enhancement of utilization of LIDAR: Preliminary study for feasibility of evaluation of wind turbine by using wind data measured by LIDAR was carried out. The comparison between the equivalent wind velocity calculated by the data measured by LIDAR and the data measured by meteorological tower was carried out. 3. Investigation of marine condition, 4) Evaluation of character of wave: To evaluate the character of offshore wave of Kitakyushu city, wave monitoring by wave meter was continued from October 2012. E) Maintenance of meteorological tower: O&M of the metrological tower was continued from October 2012. F) Summarization of the design of meteorological observation system, 1) Summarization of the simulation: Meteorological-marine interaction analysis system was studied continuously. 2) Summarization of the design of system: Observation system, power supply system and miscellaneous items were studied. G) Environmental impact analysis, 1) Ecosystem impact analysis: Ecosystem impact analysis was carried out during the operation of the wind turbine. Birds were monitored by radar in the night-time in November. Monitoring of a finless porpoise “sunameri” by using the underwater sound probing system was carried out in summer, autumn and winter. H) Other studies, 2) Fish-gathering effect analysis: Fish-gathering effect around the support structure was carried out by divers and using interval cameras.
