During the past decade, relatively few DSP methods have been applied to the electric power quality analysis area, e.g., transient power line signals. Thus, in this talk, we present various DSP approaches for several power quality issues such as detection, compression, and classification, etc.
For transient power line signal analysis, we focus on power quality degradation associated with short-time transient power line disturbances. This is because as the number of microelectronic devices increases, short-time power transient signal analysis may be more important than long-time analysis. In general, digital signal processing applications associated with the short-time transient analysis can be found in (1) detection of a transient signal on a power line, (2) compression of the transient for data transmission and archiving at a monitoring station, (3) classification of power disturbance signals, and (4) assessment of power quality for the short-time power disturbance signal. Thus, in this talk, we present digital signal processing algorithms associated with these applications, and demonstrate their better performance using simulations and actual power line transient signals.
