摘要
本文提出了一种新的直流输电系统数字仿真模型——BDF离散化数学模型。在此基础上编制的程序从原理上可适用于任何形式的直流输电系统的数字仿真。例题计算结果表明,该模型具有较高的仿真精度。
In this paper, a new mathematical model, BDF discrete circuit model, has been developed, which can be used to simulate any forms of HVDC systems in principle. Some interesting problems are also discussed in this paper, including the selection of the numerical integration algorithm, the sparse technology, the representation of the converter transformer and some general criteria used to check the validity and to estimate the precision of the digital simulation. It proved that the 4th-order BDF discrete circuit model has considerably high simulating precision.
