Abstract


Power Quality control technology is based on power electronics technology, an important part of belonging to the user the power of technology , the Unified Power Quality Conditioner (UPQC) not only to achieve the compensation of the distortion waveform , and the dynamic voltage restorer , flexible power supply on the basis of technical devices. The UPQC changed the traditional power quality control voltage or current waveform compensation as a whole to adapt to the current and voltage compensation requirements , far development prospects . Based on the improved Power quality reality, in-depth study UPQC theory , topology , the compensation component of the real - time detection and control strategies research . This paper introduces the active power filter current problems and development status ; second chapter introduces the basic principles of active power filter ; Chapter III presents UPQC device's main circuit topology and its working principle a detailed description ; voltage and current distortion component of the real-time detection and calculation methods are described in Chapter IV ; UPQC compensation control strategy , and its simulation experiment results show that the text provides the control strategy has a good compensation effect .
