Construction of micro power grid due to distributed wind power generations and power transmission facilities

根据输电线路精确记录的风向和风速波动信息，估算了九州中型风车设施产生的风能密度和年产量。结果表明，虽然风向稳定，但许多地方在可用于发电的低湍流风中并不提供高的年平均风。结果表明，利用年平均风速记录估算的潜在风能高估了考虑风的真实的湍流的潜在风能。许多风力发电设施位于风的湍流较大的地方，其发电性能往往达不到最佳水平。因此，微电网的建设需要高分辨率的风信息。

Wind power energy densities and annual productions generated by middle-scale windmill facilities in Kyushu were estimated based on information of fluctuations of wind direction and speed minutely recorded using power transmission lines. It was found that many places did not provide high annual mean wind in a low turbulent wind available for power generation though wind direction was stable. As a result, potential wind energy estimated using annual mean wind speed record overestimated those estimated in consideration of real turbulence of wind. Many windmill facilities which were located at places with big turbulence of wind will not exhibit the best performance in power generation. We concluded the construction of micro power grid requires high resolution wind information.
