| 摘 要： | 运用中尺度数值模式WRF与法国CFD软件MeteodynwT相结合的方法（WRF／WT），进行了广东省海陵岛地区的水平分辨率100m×100m的风能资源数值模拟试验，采用海陵岛上7座测风塔观测资料对WRF／WT模式的模拟风场进行误差检验，并与WRF／WAsP模式系统对单点风能参数模拟误差进行对比，研究WRF／WT模式系统在风电场微观选址和分散式风电开发利用中应用的可行性。结果表明：中尺度模式与CFD软件结合的数值模拟方法对区域风能资源分布趋势的模拟比单纯应用CFD软件更准确；WRF／WT模式系统应用于复杂地形风能资源数值模拟评估是可行的，其对区域风能资源参数分布模拟的准确率与WRF／WAsP对2km范围内风能资源参数模拟的准确率相当；WRF／WT模式系统在风速频率分布不满足Weibull分布的情况下和陡峭地形条件下有较好的模拟效果，相对WRF／wAsP有明显优势。今后需进一步研究中尺度模式与CFD软件的衔接方法，以及对中尺度模式模拟结果的误差订正。 |

| Abstract: | A combined model system (WRF/WT) of the mesoscale model WRF and the Meteodyn WT, a CFD model from France, was carried out the numerical simulation experiments of regional wind resources over Hailing Island of Guangdong Province with a horizontal resolution of 100 m × 100 m. The observational data from 7 wind towers in Hailing Island were used to test the results modeled by WRF/WT, and compared with the simulated errors to the single point wind parameters, thus studying the feasibility of WRF/WT model system in micro siting for wind farm and the application of distributed development of wind power and utilization. The results showed that, the combined model system of mesoscale model and CFD model in simulating the trends of the regional wind energy resource distribution is more accurate than CFD model used only; the WRF/WT model system used in complex terrain for wind resource numerical simulated evaluation is feasible, and its accuracy in simulating the parameters of the regional wind energy resource distribution is close to the result of WRF/WAsP simulating within 2 km. The WRF/WT model system compared to WRF/WAsP has obvious advantages when the frequency distribution does not meet the Weibull distribution or in a steep terrain. In the future, we need to further research in the interface methods of mesoscale model and CFD models, and the error correction of mesoscale model simulations. |
