摘　　要：在组网过程中,结合无线网桥的混合传输方式和IEEE 802.11标准形成交互性强的C/S架构的传输方案。对2.4 GHz和5.8 GHz频段的无线电波传输损耗进行相关理论分析和仿真计算,得到风电场的无线电波损耗模型,进而对无线链路损耗、衰落、天线增益和安装高度做出合理建议。最后通过大量测试,验证网络性能可满足项目需求,并留有足够余量,可完成多个风电机组故障诊断系统的振动监测和数据传输。In the process of networking, a interactive transmission plan with C/S framework was formed wireless bridge hybrid transmission and IEEE 802.11 standards. A series of rational suggestions were p wireless link loss, signal fading , antenna gain and installation height, through combining the radio wave loss model of wind power plant, which was developed by the theoretical analysis and simulation calculation of radio wave loss in frequency band of 2.4 and 5.8 GHz. In substantive test, it turned out that the network performance could satisfy the need of the project with adequate capacity for future expansion, to accomplish the condition monitoring and fault diagnosis of multiple wind turbines.
