Monitoring and Simulation of Power Quality Problems: A Case Study
Loads composed of lightning, personal computers, air conditioners and equipment for specific applications (some sensitive to voltage oscillations) have experienced annoying power quality problems, malfunction and permanent damages. In order to investigate such problems, this paper presents an electromagnetic transient model (ATPdraw) of the power supply system using real, recorded and calculated data. The model response is verified by simulating two real faults, which cause power quality problems and the results are compared to available oscillography, presenting good agreement. The simulation model can be used as a support tool for further power quality investigations in this specific network. Besides that, field monitoring was made to typify the disturbances and was found that instantaneous voltage sags were the most disturbing problems.
