The research on high-powered parallel 简化了暂态稳定算法迭代流程，改进了全局收敛判定方法， transient stability algorithm and its implementation become more 有效地减少了算法计算量和通信损耗。实际电网的数值计算 and more important. This paper analyzed the advantages and 结果表明，文中提出的算法计算加速比高，实时性好，因此 disadvantages of available parallel algorithms and presented a 研制的电力系统动态并行仿真程序能够满足大规模电力系统 multilevel partition scheme, which was based on power network 暂态过程实时仿真、甚至超实时仿真的要求。 regional characteristics, to reduce the computation scale and enhance the quality of n
