摘要
通过分析电力系统暂态稳定问题的特点,提出一种面向集群系统、采用隐式积分联立求解法的空间并行算法。针对电力系统分层分区的特点,对算法实现过程中的通信耗时进行了建模,提出了改进的通信算法,减少了算法的通信耗时,提高了并行效率,并且证明该通信算法具有很好的可扩展性。对实际运行的华中电网仿真计算表明,最高的仿真加速比达到了11.17,证明了所提算法的有效性。
Through analyzing the specialty of power system transient stability, this paper proposed a spatial parallel algorithm based on cluster system. This algorithm adopted implicit integration simultaneous solution method. Considering the specialty that the power system is separated into different layers and different areas, this paper built a model to simulate the communication overheads during the realization of this algorithm. The improvement of communication algorithm was also provided, which reduced the communication overheads and enhanced the parallel efficiency. The communication algorithm was also proved to be very scalable. Numerical results of Central China Power Grids have shown that the highest simulation speedup reaches to 11.17, which adequately proved the validities of the algorithms proposed in this paper.
