摘要: In this paper, a coordinated recovery strategy for multi-infeed HVDC system is proposed. A nonlinear feedforward loop used to realize the control between two controlled variables at ends first. Secondly, constant AC voltage was implemented short period after fault removal. Finally, staggered different subsystems with restart time interval optimized using steepest descent method developed. The simulation results show, proposed strategy, performance of tested has been improved lot when compared conventional strategy.
