High-Frequency Resonance Analysis and Stabilization Control Strategy of MMC Based on Eigenvalue Method
نویسندگان
چکیده
For the high-frequency resonant accident of modular multilevel converter (MMC) in real engineering, this paper, 10th order state-space model MMC is established based on dynamic phasor method. The controller for power control according to practical engineering. Then time delay input and output considered controller, Pade fitting applicable eigenvalue method introduced complete state space MMC. Based proposed model, resonance phenomenon analyzed by method, accuracy verified simulation results. Besides, it demonstrated that high causes system participation factor trajectory. Then, coupling relationship between inside d-q axis investigated, a new compensation suppress fitting, which can be used jointly with traditional good effect.
