FACTS technologies allow for improved transmission system operation with minimal infrastructure investment, environmental impact and implementation time compared to the construction of new transmission lines. FACTS provide the needed corrections of transmission functions in order to efficiently utilize existing transmission systems and therefore minimize the gap between the stability and the thermal level. Interline Power Flow Controller(IPFC) is a Voltage Source Converter(VSC) based FACTS controller for controlling power in multi-line system located at a substation. The main aim of the IPFC is to verify the power transfer capability between two or more lines and to establish the proposed voltage regulation function. In this paper, a current source converter topology based IPFC is proposed. In this structure, the dc-side current is regulated to a value larger than the peak value of the maximum line current. The injected voltage is controlled according to the desired reactive power compensation and management active power flow for master line. The decoupled state feedback control for the injected voltage with a separated dc current control is applied to the proposed system. The proposed IPFC has been simulated using the Matlab program.
