SCRIPT FILES APPROACH IN THE POWER QUALITY EVENTS GENERATION

Generation of typical power quality (PQ) events, based on Script files and virtual instrumentation, is presented in this paper. Such approach provides definition and generation of three-phase voltage signals with various PQ events defined according to relevant international quality standards. Using of Script files enables easy and flexible generation of long-time voltage signals with complex PQ disturbances, according to the predefined test algorithms and scenarios. Detailed front panels and block diagrams of developed virtual instrument for signal generation are described in the paper. As specific examples, generated signals defined using the Script files are presented. Experimental confirmation of described software supported method is performed using the three-phase PQ analyzer Fluke 435. Some specific test waveforms and obtained experimental results are shown
