摘　　要：本文提出了对调度员培训仿真器中的动态全过程进行准实时仿真的模型和算法。在仿真中，整个动态过程被划分为暂态过程和中长期动态过程两个阶段，并通过加入人工阻尼，实现了暂态过程和中长期动态过程的平稳过渡；为提高仿真速度，在不同仿真阶段采用了与其相适应的参考轴系；引入了一种能对系统变化和仿真误差作自适应调整的自动变步长方法。此外，提出了基于广度优先的快速拓扑方法和局部拓扑跟踪修正的算法，以及基于稀疏技术的快速因子表修正法。This paper proposes the simulation models and algorithm of quasi real-time dynamic simulation for dispatcher Training Sitriulator (DTS) of East China Power System. To increase the simultion speed without sacrificing the simulation accuracy, the dynamic behavior of the system is divided into transient and mid/long--term modes while artificial damping term is introduced to realize the smooth transition from one mode to the other. Adaptive reference frames and variable step sizes are employed for further increasing the simulation speed. In addition, fast topology algorithm based on width priority that can keep track with random switching operations and fast refactorization method based on sparse techniques used in this software package are also presented. Case studies of East China Power System verify the validity of the above mentioned measures.
