基于PCI控制的MMC-HVDC系统稳态控制策略研究
Study of Steady-state Control Strategy for MMC-HVDC System Based on PCI Controller
摘要
Abstract
The MMC-HVDC(modular multilevel converter-high voltage direct current)system usually adopts double closed-loop control based on PI controller,but in the two-phase rotating reference frame,there is cross-coupled term of current that needs to join the feedforward decoupling control.In order to make the whole control system simpler, PCI(proportional complex integral)control is needed to design the inner loop in two-phases stationary reference frame,then a steady-state control strategy based on PCI inner-cycle and power outer-cycle was built.The above control strategy was simulated by electromagnetic transient simulation software PSCAD/EMTDC,and the simulation results show that the designed controller has good steady-state tracking performance,and the active power and reactive power control are less affected by each other.The control strategy is effective.关键词
