In traction power supply system of China High-speed Railway, the transient process of EMU has a great difference between the state of passing by Phase-separation with electric load and passing by Phase-separation without electric load. The overvoltage caused by switch in with arc in the process will influence the correct operation of the common protection device. Based on the theoretical analysis...
This paper addresses the problem of extracting effective features for the analysis of underlying causes of power quality (PQ) disturbances. For each underlying cause, we define and extract a set of features based on analysis of voltage/current waveforms or the combination of them. The proposed feature sets are then used for building a rule-based classification framework for automatic identification...
