Transient Behavior Analysis of Offshore Wind Farm Integration System with MMC-HVDC
摘要
Abstract
For offshore wind farm integration system with modular multilevel converter high voltage direct current (MMC-HVDC),the control strategy for the wind farm modular multilevel converter(MMC)to maintain the AC voltage of the wind farm collecting system is presented,which adopts single loop in two dimensions.The detailed offshore wind farm MMC-HVDC integration system is established.The model is realized with PSCAD/EMTDC.Simulation and research under different conditions are carried out.Transient behaviors of the whole integration system during wind speed variations,wind farm collecting system fault,grid fault and single pole grounding fault of the MMC-HVDC system are studied.The results are compared with the results of a high voltage alternating current(HVAC)integration system.The study reveals that the MMC-HVDC system with the control strategies presented can keep stable operation under different faults.The results show that the proposed grid integration system and control strategies are correct and valid.关键词
