Simulation of Sub-synchronous Resonance (SSR), and Mitigation of SSR by Static Synchronous Series Compensator with Lead Lag Compensator
Abstract: This research work presents a narrative method of alleviating the SSR problem using a static synchronous series compensator (SSSC). This method is based on using the SSSC to inject unbalanced series quadrature voltages and unbalanced shunt reactive currents in transmission line just after clearing faults. When the sub-synchronous oscillations drive unsymmetrical phase currents, the developed electromagnetic torque will be lower than the condition when three-phase currents are symmetrical. The unsymmetrical …
