| Abstract: | The working principle of the phase-shifting transformer(PST) is presented briefly,and installation of PST in 500 kV transmission lines of East China Power Grid to change power flow distribution and improve the transmission capacity of the grid section is studied.Influences of PST on the short-circuit current of 500 kV buses of the Grid are discussed.Study shows that the PST can greatly improve the power receiving capability of Shanghai Power Grid and the transmission capacity of the cross-river passage of Jiangsu Power Grid,and will play a positive role in reducing the short-circuit current of 500 kV buses of East China Power Grid. |

| Keywords: | phase-shifting transformer(PST) power flow control short-circuit current improving transmission capacity |
