| Abstract: | The concept of power quality is presented, including definitions and basic characteristics of frequency deviation, voltage deviation, temporary drop-out of voltage and voltage interruption, electric-magnetic transient state, distortion of wave shape, unbalance of three-phase, voltage fluctuation and flickering, harmonic and uncontinuous harmonic. Various factors affecting power quality are analyzed in detail and possible harm of unqualified power quality is discussed. Production mechanism and affecting range of uncontinuous harmonic are expounded and suggestions for formulating related standards are given. The basic contents of the existing national standards for the power quality are described. |
| Keywords: | power quality electric-magnetic temporary state temporary drop-out of voltage uncontinuous harmonic |
