Power Quality Analysis and Evaluation at Water Pumping Station Supplied by Medium Voltage

Özet

Abstract

Power Quality (PQ) related issues are of the most concern nowadays. The widespread use of electronic equipment, such as information technology, power electronics applications, programmable logic controllers (PLC), led to a complete change of electric loads nature. These loads are simultaneously the major causers power quality problems. Due to their non-linearity, all these loads cause disturbances in the voltage waveform. This paper deals with the measurement, analysis and evaluation of the power quality parameters in a water pump-ing station with a medium-voltage level. Power quality parameters such as voltage, current, active power and harmonics are measured, analyzed and evaluated taking into considera-tion IEEE 519-1992 standards.
