摘要
现阶段国内风电场风速传感器在使用中冻结现象严重,输出精度不高,信号受干扰严重。文中以风杯式测风传感器为原型,针对风力发电场的特殊要求分析,提出电路解决方案,用ProtelDXP设计,Proteus仿真,并对电路精度误差进行分析。结果表明:针对风杯风速传感器的内部电路设计能有效地提高测量精确,在低温环境下适应性强,输出信号抗干扰能力提高。
This paper designed and analyzed a wind measuring instrument for the generate wind power electricity.It designed and modelled the inside circuit by using the software ProtelDXP,using the software Proteus to simulate and calculate the circuit,used the theory knowledge to analyze the error of the circuit.The result of theory calculation and simulation analysis show that,it can effectively improve measuring accurateness in this kind of instrument.It is durable and rigid which can easily adapt to complex environment,and output signal is the industry standard serving for wind farm.
