Transient Power Quality Signal Generator and Detector Platform
Chen Chunling, Huihui Qi, Wei Zheng, Pengfei Wu · Energy Procedia · 2012
a transient power quality detective platform which includes the disturbance signal's generator and detector is designed based on virtual instrument technology. The platform is developed under LabVIEW environment. It's generator can give the transient disturbance signals according to the standard EIEE1159-1995, such as voltage swells, voltage sags, voltage fluctuation and transient oscillation. The detector uses Hilbert phase-shifting Transform method to realize the real-time detection to the disturbance signals from the generator. The test example shows that the platform for transient disturbance detection is visual and convenient, and the phase-shifting method is effective for transient power quality disturbance signal's detection.
