Review of power quality indices of a DC distribution network
摘要
Abstract
With the integration of new energy sources and the continuous improvement of the controllability and flexibility of DC loads,DC distribution networks show broad development prospects.The integration of a large number of distributed power sources,sensitive equipment,and power electronic devices imposes stricter requirements on the power quality of DC distribution networks.This paper introduces the typical wiring structure,voltage level range,and control methods of converters in DC distribution networks.Based on existing references and standards,it analyzes the disturbance mechanisms of power quality phenomena in DC distribution networks and proposes a more standardized DC power quality index system.This system is divided into two types:variation and event.The variation type includes voltage deviation,rapid voltage change,voltage flicker,voltage imbalance,and ripple;the event type includes voltage sag,voltage interruption,and overvoltage.The measurement methods and limit requirements for DC power quality indicators are summarized and analyzed.Finally,the future research directions for the index system,measurement methods,and limit requirements of DC power quality are discussed.关键词
