Review of Equivalent Operation Test Methods for VSC Valves
In the factory,routine tests of VSC(Voltage Source Converter)valves should be carried out to ensure the operation reliability of the VSC-HVDC(Voltage Source Converter Based High Voltage Direct Current)system.However,the VSC valves with higher voltage and larger capacity requires suitable equivalent test methods.Firstly,this paper traces the process of the DC(Direct Current)transmission technology and analyzes the significance of the research on the equivalent operation tests of the VSC valves.Next,the equivalent principle of tests is explored,and the reference and development of the LCC-HVDC(Line Commutate Converter Based High Voltage Direct Current)tests are illustrated.Finally,on the basis,the researches on the equivalent test equipment of the VSC valves at home and abroad are summerized.Through the comparison of the key indicators,the optimization direction and key technologies of the equivalent operation test methods are prospected.
