【Abstract】 Unified Power Flow Controller (UPFC) is a novel power transmission control device by which the parameters of transmission system such as voltage, line impedance and phase angle can be dynamically controlled. In this paper firstly a MATLAB modeling is established, then by means of a concrete case the regulation of voltage and power by the series and shunt part of UPFC under the steady state is analyzed in detail. The simulation results show that UPFC can regulate active power, reactive power and voltage of transmission system within a wide scope. MATLAB model of UPFC provides a tool by which the feasibility of UPFC can be estimated and what kind of influence of UPFC on transmission system can be evaluated. Finally the effectiveness of numerical calculation method based on MATLAB model is successfully validated by transient network analyzer (TNA).更多还原
