Abstract
The AC system voltage control strategy was researched based on Xiangjiaba to Shanghai (abbr. XS) ultra high-voltage direct current (UHVDC) rectifier side (Fulong station) weak system during XS UHVDC project system commissioning test, and the countermeasure method prevented to fault for monopole rated power operation test was proposed. The variety procedure of DC voltage, DC current and firing angle and so on were analyzed, the UHVDC control system characteristics, AC side and DC side over voltage were analyzed during monopole rated power protective reduced voltage test. The reactive power and voltage control parameters were proposed and carried out to set temporarily at Fulong station, in order to guarantee AC bus voltage stability and reduced voltage 70%test success during monopole rated power operation test. The validity of system calculation analysis results was verified before XS UHVDC system test by rectifier station reactive power and voltage calculation analysis based on DC parameters measured in the test. The DC voltage and current intense variety in rectifier could not infect the system safety and stability operation by analyzing system voltage stability.关键词
