Abstract: Because of seasons, there will be some problems in Suzhou Southern grid, such as limited transfer capacities of power imported channels, unbalanced power flow distributions and so on, which explains the necessity to install the 500 kV unified power flow controller (UPFC) in Suzhou Southern grid. Introduction was made to the application status of UPFC. This paper carried out analysis and calculation for Suzhou Southern 500 kV grid and discussed the functions of UPFC device in power flow control and voltage support. The results show that after the UPFC device was added, the transmission bottleneck of this grid is effectively solved, as well as a large area of limited load problem after direct current twin pole shutting.
Key words: unified power flow controller (UPFC); Suzhou Southern grid; power flow control; voltage support
