鄱阳湖区风能资源数值模拟

Numerical Simulation of Wind Energy over Poyang Lake Region

引入区域边界层模式RBLM（Regional Boundary Layer Model）对鄱阳湖区120km×180km范围内的风能资源进行数值模拟，发现地形作用对鄱阳湖区风能资源分布具有关键作用。模拟结果和气象台站的同期观测数据相比较，风速分布有比较好的相似性：庐山及庐山东面的高山区域年平均风速大于3．5m／s，环鄱阳湖区域年平均风速大多在2．0～3．0m／s之间，在离湖岸较远的部分区域风速小于2．0m／s。在大尺度范围内模式模拟结果对寻找大风区域有一定的指导意义，对环鄱阳湖区域风电场选址具备参考作用，现阶段采取数值模拟结合重点区域实测是一个比较好的摸清风能资源储量的方法。

Region boundary layer model（RBLM） was introduced to carry out the numerical simulation of the wind energy resources in the district of 120 km ×180 km area in the Poyang Lake region. The result was compared with the corresponding data from the meteorological observatory and found a good similarity between them. The annual average wind velocity in the mountain area of Lushan and east to Lushan was over 3.5 m/s, that in the Poyang Lake zone was 2.0 - 3.0 m/s, and that in the zone farther from the lake bank was below 2 m/s, numerical simulation plus on - the - spot observation is practical in locating the zones of relatively rich wind energy resources.
