Abstract

This paper proposes a method to adjust the gain control algorithm in a STATCOM controller. The salient features of this method are the automatic detection of subsynchronous resonance in power systems and the automatic gain tuning of the STATCOM controller to mitigate subsynchronous resonance. The algorithm uses controller input to produce a delay-embedded time-series plane and is implemented in the STATCOM controller to detect the time of local oscillation. A new gain value is calculated in the radius of the trajectory extracted from the geometric map using phase space reconstruction and the mitigation of voltage and reactive power oscillation is confirmed by electromagnetic transient analysis.
