摘要:
功率变流器是发电系统与电网的接口,对其可靠性要求很高。在温度频繁变化的环境影响下,变流器极易发生故障。及时准确诊断变流器故障类型,是故障诊断的关键。该文分析变流器开路故障模式的基础上,利用改进的加窗短时傅里叶变换获取各模式下故障信息,并进行对比分析,找出了各开路故障模式下的故障频谱特征及规律,为变流器开路故障分类提供了理论依据。
Abstract:
Power converter is the interface between generating system to power grid, which should has high reliability. It failure easily when work-temperature change frequently or influenced by environment. Timely and accurate diagnosis on converter fault types is the key to ensure the normal operation of the system. This paper analysis fault mode of power converter, get the fault information in different mode by using windowed Short-Time Fourier Transformation (STFT) to contrast analysis, and then found out the fault spectrum characteristics and rules of each of them. These work provide theoretical basis for converter fault classification.
