Abstract
This study presents a novel data processing method for Synchronized Waveform Monitoring Units (SWMUs), which operate at high sampling rates of up to 1024 samples per cycle. Considering the high rate of sampling data, it is important to translate and compress the data size. The proposed method introduces the synchronized Lissajous DQ curve, leveraging the Park Transform in the Exact Self-synchronized method to compress three-phase voltage and current data from as few as two SWMUs into a single plot. Unlike existing single-phase synchronized Lissajous curves, which require one plot per phase, this approach represents three-phase conditions in a single plot, enabling efficient event detection and characterization, such as incipient and high impedance faults, without requiring network parameters. Validated on the IEEE 33-bus distribution system, the method demonstrates superior data compression and maintains information density, achieving 100% event classification accuracy in LSTM-based validation while reducing prediction time by 43.3-43.9% and dataset size by 66.7% compared to the existing techniques.
