The short-circuit fault current on the dc side affects the operation safety of the multiterminal flexible HVdc transmission system seriously. The resistance-type superconducting fault current limiter (RSFCL) has received extensive attention in limiting the dc impact current because it has fast response speed and zero impedance at steady state. YBCO tapes are susceptible to delamination damage under large dc impact and it will affect the operation of RSFCLs. However, the existing methods of distinguishing the delamination damage of YBCO tape need an extra observation or testing after dc impact. These methods cannot meet the requirements for monitoring and protection when RSFCLs coming into use in the power system. In this article, the Hilbert–Huang transform (HHT) is used to analyze the delamination damage of YBCO tapes under dc impact to avoid extra observation and testing. The dc impact test on the YBCO tape sample is carried out and the test data are obtained. HHT is applied on the joule thermal power waves (TPWs) of the YBCO tape samples obtained from the dc impact test as the input signal. Hilbert spectrums and instantaneous energy spectrums (IEs) of the TPW signals are calculated and the difference between IEs of TPW signals of intact samples and delaminated samples is shown and explained. The feasibility of IEs of TPW signals can be as a monitoring target to avoid the stratification damage of YBCO tapes. The proposed method may aid in the on-load monitoring on RSFCLs and provided a new tack for related research.

基于希尔伯特-黄变换的直流冲击下YBCO胶带分层损伤研究

直流侧短路故障电流严重影响多端柔性高压直流输电系统的运行安全。电阻式超导故障限流器(RSFCL)因其响应速度快、稳态阻抗为零,在限制直流冲击电流方面受到广泛关注。YBCO 胶带在大直流冲击下容易发生分层损坏,并会影响 RSFCL 的运行。然而,现有区分YBCO胶带分层损坏的方法需要在直流冲击后进行额外的观察或测试。这些方法不能满足RSFCL 在电力系统中投入使用时的监测和保护要求。在本文中,希尔伯特-黄变换 (HHT) 用于分析 YBCO 胶带在直流冲击下的分层损坏,以避免额外的观察和测试。对YBCO胶带样品进行直流冲击试验,得到试验数据。HHT 应用于从直流冲击试验中获得的 YBCO 胶带样品的焦耳热功率波 (TPW) 作为输入信号。计算了 TPW 信号的希尔伯特谱和瞬时能谱 (IE),并显示和解释了完整样品和分层样品的 TPW 信号的 IE 之间的差异。TPW信号IEs的可行性可以作为监控目标,避免YBCO带的分层损坏。所提出的方法可能有助于RSFCLs的负载监测,并为相关研究提供了新的思路。对YBCO胶带样品进行直流冲击试验,得到试验数据。HHT 应用于从直流冲击试验中获得的 YBCO 胶带样品的焦耳热功率波 (TPW) 作为输入信号。计算了 TPW 信号的希尔伯特谱和瞬时能谱 (IE),并显示和解释了完整样品和分层样品的 TPW 信号的 IE 之间的差异。TPW信号IEs的可行性可以作为监控目标,避免YBCO带的分层损坏。所提出的方法可能有助于RSFCLs的负载监测,并为相关研究提供了新的思路。对YBCO胶带样品进行直流冲击试验,得到试验数据。HHT 应用于从直流冲击试验中获得的 YBCO 胶带样品的焦耳热功率波 (TPW) 作为输入信号。计算了 TPW 信号的希尔伯特谱和瞬时能谱 (IE),并显示和解释了完整样品和分层样品的 TPW 信号的 IE 之间的差异。TPW信号IEs的可行性可以作为监控目标,避免YBCO带的分层损坏。所提出的方法可能有助于RSFCLs的负载监测,并为相关研究提供了新的思路。计算了 TPW 信号的希尔伯特谱和瞬时能谱 (IE),并显示和解释了完整样品和分层样品的 TPW 信号的 IE 之间的差异。TPW信号IEs的可行性可以作为监控目标,避免YBCO带的分层损坏。所提出的方法可能有助于RSFCLs的负载监测,并为相关研究提供了新的思路。计算了 TPW 信号的希尔伯特谱和瞬时能谱 (IE),并显示和解释了完整样品和分层样品的 TPW 信号的 IE 之间的差异。TPW信号IEs的可行性可以作为监控目标,避免YBCO带的分层损坏。所提出的方法可能有助于RSFCLs的负载监测,并为相关研究提供了新的思路。
