摘要
为了提高HVDC研究、设计的效率及可信性,同时满足实际复杂的HVDC系统的仿真研究要求,弥补PSCAD软件因模块封装导致软件使用灵活性降低的问题,基于ATP/EMTP电磁暂态仿真软件,利用其强大的自定义模块功能,搭建了CIGRE直流输电模型,开展系统仿真分析,并与PSCAD中标准的CIGRE模型的仿真结果进行比对分析,验证了所搭建的HVDC模型的正确性及可行性;选用适当的仿真步长,保证计算结果正确性同时,提高了计算效率。
In order to improve the designing efficiency and validity of simulation results of HVDC system and to meet the simulation requirements of modeling real complex HVDC system,and to further remedy defects that modular packages used in PSCAD/EMTDC decrease software flexibility,we mainly adopted ATP/EMTP simulator to model CIGRE HVDC Benchmark system and provided a detailed description of the HVDC system and its controller.Moreover,the system performances of steady-state and transient-state were analyzed,and the CIGRE HVDC standard model was compared with PSCAD/EMTDC.The simulation results prove that modeling method is correct and feasible,and selecting proper simulation step not only improves the performances of system but also shortens execution time.
