摘要
风电场要具备一定的故障诊断能力,而其故障诊断的准确性主要取决于风力发电故障诊断系统的通信网络。以风力发电故障诊断系统中的通信网络为研究对象,采用全球微波接入互操作性(WiMAX)技术传输风力发电机组与监控端之间的预兆故障特征数据。WiMAX具有传输速率高、传输距离远、抗干扰能力强、保密性好等技术优点,因此在链路存在干扰的情况下仍然可以准确地传输数据。对该系统进行了WiMAX组网设计,同时使用网络仿真软件OPNET14.5对WiMAX的抗干扰性能进行仿真论证,结果表明WiMAX技术具有良好的抗干扰能力,适用于风力发电故障诊断系统。
The ability of fault diagnosis in wind farms depends mainly on its communications network. The communication network with global Interoperability for Microwave Access technology （WiMAX） was established to research the anti-interference characteristics in the fault diagnosis system of wind power generation. WiMAX was used to transfer the failure characteristics data between wind turbine and Monitoring client. The advantages of WiMAX technology, such as high transmission rate, well protected privacy and high anti-interference ability, ensured the data transmission accuracy. WiMAX network was designed according to the working principle and characteristics of wind power fault diagnosis system. Network simulation software OPNET14.5 was used to simulate the anti-interference performance of WiMAX. The simulation results show that WiMAX could work well when the link had interference, so it could well apply in the fault diagnosis system of wind power generation.
