Optimized Interaction of PODC and SSSC To Improve the Transient Stability Performance In Power System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 10
Abstract
The enlargement of the contemporary power system has lead to an increasing difficulty in the study of power systems, also presents new challenges to power system stability and in meticulous to the aspects of transient stability. This paper presents the algorithm for interfacing Voltage Sourced Inverter with Static Synchronous Source Series Compensator (SSSC).The modelling of the controller plays a major role in the performance of the SSSC. The performance of SSSC for different mode of operation using PI controller and sliding mode controller is being studied. The Power Oscillation Damping Circuit (PODC) is used to damp out power oscillation. The simulation was performed on a 9-bus power system modelled for stability studies. The results clearly indicate that introduction of SSSC devices in an appropriate location increases the power flow of the system and improves transient stability, by controlling its mode of operation by developing sliding mode controller module. The simulations and analysis were carried out using the MATLAB Software Package.
