摘要：
The subsynchronous oscillations caused by wind power fluctuations have characteristics of variable oscillation frequency, abundant related dynamic devices and complicated influencing factors, the current damping control devices are difficult to realize the effective mitigation of this phenomenon, it is necessary to study the applicable additional damping control methods. The characteristic equations and transfer functions are deduced for integrated power systems with direct drive permanent magnet synchronous generator (PMSG) based wind turbine generators by linearization methods, and frequency response characteristics of the system under different conditions are obtained. A parameter design method for subsynchronous oscillation damping controller of wind turbine generator based on Nyquist stability criterion, and a parameter optimization method based on particle swarm optimization are proposed. By eigenvalue analysis and time domain simulation, the mitigation effect of damping controller on subsynchronous oscillation is analyzed. Results show that the designed damping controller based on the above method is adaptable under various operating conditions. © 2019 Automation of Electric Power Systems Press.
