本文提出了一种基于地理位置的分区方案，将整个电力系统划分为子系统和协调系统。提出了一种暂态稳定仿真（TSS）的空间并行算法，可同时计算所有子系统。然后，子系统和和谐系统交替迭代求解。为了进一步提高效率，采用了多种优化技术。在微机机群上实现了对1923个节点、2280条支路、173台发电机的大型电力系统的实时仿真。试验结果表明，该算法适用于大规模电力系统的实时TSS。
In this paper, a partitioning scheme based on geographical location is proposed to divide the whole power system into subsystems and a harmony system. A spatial parallel algorithm for transient stability simulation (TSS) is presented to compute all the subsystems simultaneously. Then the subsystems and the harmony system are solved alternately and iteratively. Several optimization techniques are adopted to further improve the efficiency. Real-time simulation is achieved for a large power system with 1923 nodes, 2280 branches, and 173 generators on a PC cluster. The test results demonstrate that the proposed algorithm is lit for real-time TSS for large-scale power systems.
