Control of Active and Reactive Power Flow in Multiple Lines through Interline Power Flow Controller (IPFC)

By Indra Prakash Mishra and Sanjiv Kumar


Abstract — In this paper a circuit model for IPFC is developed using series coupling transformers and comparison of active and reactive power of Transmission Lines with and without IPFC is presented using the proposed circuit model. Comparison is also done with individual Static Synchronous Series Compensators (SSSCs), one on each line of a two line system and the results are compared with the previous one. MATLAB with Simulink and SIM POWER SYSTEMS tools are used for simulation of Transmission lines and IPFC in open loop and closed loop configurations. A common DC link within the IPFC is able to facilitate real power transfer among the lines of the transmission system. Also each inverter can provide reactive power compensation independently. IPFC is developed with the objective of balancing real and reactive power flow among multi-lines and to transfer power from overloaded to under loaded lines. Second objective of IPFC is to compensate against reactive voltage drops and the corresponding reactive line power, thereby increasing the effectiveness of the compensating system against dynamic disturbances. An attempt is made in the present work to develop circuit model for four-bus system with IPFC and two series coupling transformers
