EVALUATING THE ROBUSTNESS OF FACTS-BASED STABILIZERS AND PSSS BY DAMPING TORQUE ANALYSIS IN MULTI-MACHINE POWER SYSTEMS
摘要
In this paper
the damping torque analysis is applied in a multimachine power system installed with FACTSbased stabilizers and PSSs
which leads to the establishment of a multichannel model describing the pattern of the stabilizers to provide damping to the oscillation modes in the power system. Based on the model
an index is proposed to evaluate the robustness of the stabilizers to the variations of system operating conditions. One application of the index proposed is demonstrated to select the operating condition of the power system
at which the stabilizers are designed to ensure their robustness. This demonstration also reveals the inherent disadvantage of simultaneous tuning techniques for the coordinated design of multiple stabilizers in multi-machine power systems.
