Overvoltage of the Power System Integrated With High Proportion of Power Electronics(Ⅰ):Definition,Classification and Relevant Requirements
摘要
Abstract
With the integration of large scale of renewable energy plants and large capacity AC/DC transmission projects,the power system integrated with high proportion of power electronics has been formed,and the security and stability problems represented by power system overvoltage have become increasingly prominent.However,the causes and mechanisms of overvoltage are relatively complex,which restricts the capability of renewable energy generation and HVDC transmission.Based on the above considerations,this paper introduces the definition,classification,and characteristics of power system overvoltage.Further,focusing on three scenarios of the actual power grid where the overvoltage problem is more prominent,the causes of overvoltage,the voltage capability constraints of various types of equipment and their limiting factors are analyzed.Then,possible security risks of traditional AC equipment and power electronic equipment under different scenarios are illustrated.At the end of this study,the overvoltage analysis process is summarized,and its applicability is demonstrated through a time-domain simulation example.关键词
