Simulation study on subsynchronous oscillation character of large steam turbine generators in the hybrid transmission network environment
Subsynchronous oscillation situation of Hulun Buir League power system is complicated for there are series capacitor compensation lines as well as DC transmission lines. In this paper, a comprehensive introduction to power plants’ Subsynchronous oscillation and mitigation situation in Hulun Buir League power system is given. The sustained low amplitude Subsynchronous oscillation phenomenon in Ewenki Power Plant is emphasized. Aiming at the phenomenon, a simplified model of Hulun Buir League power system is proposed and the time-domain simulation based on MATLAB is carry out. Simulation results match with the practical situation, which verified the correctness of the model. This research provides basis for further study of Subsynchronous oscillation mitigation in Ewenki Power Plant .
