Novel Adaptive Loss-of-Excitation Protection Criterion Based on Impedance Circle of Steady-State Stability Limit
This paper presents a novel loss-of-excitation (LOE) protection criterion based on the impedance circle of steady-state stability limit (SSSL),which can automatically adapt to the change of system operating modes.In combination with some blocking measures to prevent the influence of non-LOE working condition,a new adaptive LOE protection scheme is proposed,which can correctly and reliably operate in both LOE and uon-LOE working conditions.Simulation results demonstrate the effectiveness of the proposed scheme.
