为揭示风机参数对江苏省陆上风电场运行噪声分布规律的影响，剖析其关联程度，采用现场测试与数值模拟相结合的方式，选择4个典型陆上风电场开展现场噪声强度监测试验，取得不同单机容量、风机倒塔高度及风电场运行风速情况下的实测噪声数据，作为边界条件进行数值模拟分析。结果表明，风电场相同位置噪声强度与单机容量、风机倒塔高度及运行风速呈正相关，且当风电场运行风速达到额定风速后，噪声分布范围几乎不变；风机密集区域受噪声叠加效应影响，噪声衰减速率显著降低。模拟结果可为江苏省后续陆上风电场布置提供一定参考。

To reveal the impact of wind turbine parameters on the noise distribution pattern of onshore wind farms in Jiangsu province and analyze the correlation, a combination of field testing and numerical simulation was adopted.Typical on-site noise tests of four typical onshore wind farms have been conducted and measured noise data under boundary conditions in which single machine capacities, wind turbine tower heights or wind farm operating wind speeds were varied. Subsequently, the data acquired in the previous step is used as boundary conditions for numerical simulation analysis. The results indicate that the noise intensity at the same position in the wind farm is positively correlated with single machine capacity, wind turbine tower height, and operating wind speed. Moreover, once the wind farm operating wind speed reaches the rated wind speed, the noise distribution range remains almost unchanged.Due to the noise superposition effect, the noise decays more slowly in where wind turbines are densely distributed. The simulation results can provide certain references for the subsequent layout of onshore wind farms in Jiangsu province.
