| 摘 要： | 为了对故障后暂态全过程进行仿真分析,提出了基于暂态分量衰减过程的输电线路自适应仿真思想。根据频率参数误差分析,建立了模型自适应转换判据。应用面向对象技术将线路的行波模型、π型暂态模型、π型稳态模型和故障预处理模型相结合,实现了输电线路暂态自适应仿真计算。仿真实验结果表明:该模型完整地描述了输电线的暂态过程,不仅具有精度高和转换判据可靠等特点,而且减少计算时间一半以上。可用于电力系统过电压、短路故障、保护动态行为、暂态稳定以及交直流系统相互作用等问题的研究。

| Abstract: | Self-adaptive calculation models based on the transient decay were used to analyse transient entire process. The self-adaptive switching criterion based on the frequency parameter error was set up. The object oriented programming, which combines travelling wave model, lumped parameter transient model, lumped parameter quasi-stable model and pre-treatment model, is used to implement the calculation. The simulation results show that the proposed models not only accurately describe the entire transient process but also effectively reduce the calculation time. The method can be used to study over-voltages, short-circuits, stability, protection problem and interaction of the AC/DC systems. |
