Development of pulse fault sequence analysis application with kstar data integration system *

The Korea Superconducting Tokamak Advanced Research (KSTAR) interlock related systems are configured with various system such as fast interlock, supervisory interlock, plasma control, central control, and heating devices using various types of hardware, software, and interface platforms. For each system, monitoring and analysis tools are already well-developed. However, for the analysis of system fault behaviour, these heterogeneous platforms do not help finding the relation of failure. When the interlock events are latched or pulse is stopped by PCS, events are transmitted to different actuators and it could make other events via various interface. In other words, it could lead another factor of fault causes on different systems. Through this application, we will figure out the sequence of fault factor during the pulse-by-pulse KSTAR operation. The KSTAR Data Integration System (KDIS) is configured with KSTAR event-driven architecture and data processing environment. This application has been developed on the KDIS environment and synchronized with KSTAR event. This paper will present the development of shot fault sequence analysis application and its environment configured with KDIS.
