Abstract
His article mands the defintion, term, and performance criterion of power energy quality, summaries the appliance scope and difference types of these criterions, analyzes emphasesly the main content of six national power energy quality standards that had been printsmaned, explains some methods to improve relative quality according to practical operation: Passive filter, active filter, SVC and so on , introduces their basic structure and principle, owever these measures can only solve stable voltage quality problems. his paper presents the pensation technique in order to resolve dynamic energy quality problem. It is just root approach to
restrain power quality question . his article takes resonable conclusion finally: It is more effective to apply FACS and pensation approach, and this is the direction to researchpower energy quality.
