Abstract :
The control and modulation scheme of DC system greatly effect on transient stability in AC/DC hybrid power grid. Taking Southern China Power Grid in the year of 2015 for example, when fault occurs in the sending system Yunnan power grid, influence of modulation scheme such as large power flow modulation and bilateral frequency modulation on transient stability margin of hybrid system is explored. Study results are available for reference in the programming and the making of DC modulation measures for ultra-high voltage Yunnan-Guangdong transmission system in the year of 2015.
