A DSP based Three Phase Power Quality Analyzer for Motor Drives

모터 구동장치를 위한 DSP기반 3상 전력품질분석 시스템

This paper presents a digital instrument for the power quality analysis in three phase power system where current waveform is non-sinusoidal. It is based on C31 DSP and on a special high-speed data acquisition system. Voltage and current waveforms are acquired and processed by using a simple average power algorithm, The paper also goes on to discuss the performance of an instrument prototype both in terms of accuracy and speed of measurement.
