Personal computer-based electrical power quality signal generator
Abstract
Electrical power quality signal generator, capable of reproducing power quality disturbances in accordance with European quality standard EN50160, is presented in this paper. Signal generator is divided in two parts: LabVIEW based virtual instrumentation software for defining the disturbance parameters and hardware electronics for signal generation (data acquisition card and power amplifier). The paper focus is on the design of power amplifier for scaling the data acquisition card output voltage level to the nominal power line voltage (230 V). Developed signal generator can be used for generation of reference signals useful for testing of power quality measuring instruments and various algorithms for power quality disturbance detection. In such manner, this PC based signal generator can be used as very good and cost effective alternative to very expensive instruments for testing of power qulity meters and analyzers.
