摘要
为了实现风力发电机噪声的精确评估,研究了基于IEC 61400-11标准的风力发电机噪声音调分析的方法,设计了音调分析仪的软件架构和工作流程,在此基础上利用虚拟仪器技术开发了虚拟式风力发电机噪声音调分析仪。音调分析仪的实际应用结果表明,其分析结论与国际权威的风力发电机认证机构MEASNET成员单位的分析结论保持一致,可以将其用作衡量风机性能指标的分析仪器。
In order to implement accurate noise assessment of wind turbine, a method for identifying tonality of noise emitted by wind turbine was studied based on the specification of IEC 61400-11. The software architecture and workflow of the tonality analysis instrument were designed and developed with the virtual instrument technology. Application results of this instrument show that the analysis conclusions accord with the ones given by MEASNET member and it can be used as an analysis instrument to value the performance of wind turbine.
