Study of the Test Equipment for UPFC

The paper describes the method and steps for determining the parameters of unified power flow controller (UPFC). Using the power model to determine the operating limits of UPFC, Which include: transmission line voltage magnitude and phase inserted by the series converter, the current going through the series converter, the current inserted by the shunts converter, the active power exchanging between the series and shunts converter, the line-side voltage of the series and the bus voltage of the shunts. When all of these limits are satisfied, the functions of UPFC can be brought to play completely. A test UPFC equipment used in dynamic analogy systems is designed. Simulation results using EMTDC demonstrate that UPFC can improve the voltage and power flow of the system rapidly and effectively when all the operating limit condtions are satisfied.
