High-frequency Time-series Data Computing System and Its Application in Insulated Gate Bipolar Transistor Fault Diagnosis of Flexible DC Transmission Station
the computing and processing capability of high-frequency time-series data is critical to ensuring the safe and reliable operation of key devices represented by insulated gate bipolar transistors (IGBTs). When handling high-frequency IGBT fault recording data
traditional computing methods often suffer from insufficient real-time performance and large time alignment errors
making it difficult to meet the requirements for rapid fault diagnosis and isolation. To address this issue
this paper proposes a high-frequency time-series data computing system for the scenario of high-frequency monitoring and fault diagnosis of IGBTs in flexible DC transmission stations. The system adopts a double-buffer out-of-order correction method to guarantee the complete alignment of high-throughput data
designs a streaming dynamic delay computation engine to achieve microsecond-scale snapshot processing
and introduces a reentrant computation window verification mechanism to improve result reliability. Experimental results show that the proposed system can significantly enhance the real-time performance and accuracy of data computation in application scenarios such as IGBT fault diagnosis
and provide effective support for condition monitoring and rapid fault isolation of key components in flexible DC transmission stations.
