Presentation of Real-Time TFR-data

Sammanfattning: In a high-voltage direct current system (HVDC), a process is continuously recording data (e.g., voltage sampling). To access this data, the operator must frst set triggers, then wait for the transient- fault-recording (TFR) to complete, and fnally open the recorded fle for analysis. A more refned solution is required. It should allow the operator to select, add and watch the measuring points in real-time. Thus, the purpose of this thesis work is to read, process and present the samples continuously, as series in a graphical chart. Programming will be done by using iterative and incremental development. The result of this thesis work has been an executable application with a graphical user interface (GUI), able to showing the content in the buffers as a graph in a chart.
