Power Quality Investigate by Using the Varying of Voltage Parameter
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 4
Abstract
To evaluate the power quality of a power system which is necessary to monitor the power quality of the power supply environment. The purpose of monitoring is mainly to determine power quality problems or to assess power consumption at a specific location. The ideal power supply quality should have the characteristics of such as no voltage variation, no power outage, and no frequency variation. In this research, use the low voltage event recorder to collect data, analyze data and to judge including five kinds of Irregular power quality voltage events such as voltage swell, voltage sag, power interruptions, frequency changing and voltage transients. By statistically and analyzing the above five abnormal voltage parameters or waveform changes that can infer the power quality of the power supplier with discriminated by quantization. There are selected two types of research objects connected and powered to the same main transformer, one is high voltage keycustomer and another is low voltage power demand of underground feeder. The chosen user is installed and connected by parallel connection to the voltage event recorder Fluke VR101 through a communication network or channel with micro-processor and fed into database by mathematics method to calculate the events percentage or said reliability of power provider.
