| 摘 要： | 针对市场条件下电力系统暂态稳定性仿真计算问题,应用基于支路分割的系统分裂方法,对子系统间协同完成暂态稳定性仿真分析的并行算法进行了研究,提出了基于区域迭代的暂态稳定性并行算法.该算法在虚拟异步并行计算平台(VAPP)上得到了实现,并用新英格兰10机39节点系统算例和暂态稳定性仿真程序(TSSP)进行了验证.还考察了在3子系统分裂和5子系统分裂情况下,每积分步上子系统间的通信次数和并行计算加速比.该算法是粗粒度的,在一定程度上可适应于市场条件下的电力系统暂态稳定性分析.

| Abstract: | To deal with the power system transient stability simulation under the market environment, it is analyzed for the parallel algorithm to accomplish the transient stability simulation through subsystem synergic computation based on system splitting by branch cutting method and a parallel transient simulation method based on subsystem iteration is presented. The parallel algorithm is implemented on the Virtual Asynchronous Parallel Platform (VAPP) and the correctness is testified by the comparison of the simulation result of New England 10-generator 39-bus systems with a verified transient stability simulation program TSSP. The communication times among subsystems in one integral step and the speedup ratio of parallel calculation are investigated for the system of 3-subsystem splitting case and 5-subsystem splitting case. The presented algorithm is coarse grain and is adapted to the power system transient stability analysis under market environment. |
