摘　　要：传统双馈风电并网系统暂态电能质量扰动检测方法直接提取特征量,未对电压信号进行降噪处理,检测开销较高。通过双馈风电并网系统暂态电能质量扰动检测研究,对电压信号进行降噪处理,并对其进行特征量提取,设计暂态电能质量检测流程,实现双馈风电并网系统暂态电能质量扰动检测。结果表明,该研究方法检测开销较低,效率较高。The traditional transient power quality disturbance detection method of doubly-fed wind power grid-connected system directly extracts the feature quantity,but does not denoise the voltage signal,and the detection overhead is high.Through the research on transient power quality disturbance detection of doubly-fed wind power grid-connected system,the voltage signal noise reduction was processed,and the characteristic quantity was extracted,and the transient power quality detection process was designed to realize the transient power quality disturbance detection of doubly-fed wind power grid-connected system.The results show that the detection cost of the proposed method is low and the efficiency is high.
