Research and Test of a Generator Terminal Subsynchronous Damping Controller Based on Power Electronic Converter
摘要
Abstract
A novel generator terminal subsynchronous damping controller (GTSDC) based on power electronic converter was proposed and developed to mitigate subsynchronous resonance (SSR), a serious problem confronted by larger turbine-generators connected to series-compensated power systems. The proposed GTSDC is composed of a multimodal subsynchronous damping controller and a high-power current-tracking inverter. It can depress the torsional vibration by injecting controllable currents at complementary frequencies to torsional modes into the stator of the target generator. Its working principle and designing approach were elaborated in the paper. A practical equipment with a rating of 10 MVA/22 kV had been manufactured and then tested on a 660 MW turbine-generator at Shangdu Power Plant. Test results verified that GTSDC can improve modal damping considerably and suppress sustained torsional oscillation effectively. It provides a new countermeasure to inhibit subsynchronous resonance and oscillation.关键词
