Abstract
With the development of modern power system, real-time simulation and on-line control are becoming more and more critical. Transient stability analysis, where the most intensive computation locates, is the bottleneck of real-time simulation for large-scale power system. Thus, the key to achieve the real-time simulation of large scale power systems is to find the new transient stability algorithms and parallel software with high-performance computers. This paper presents a new spatial parallel transient stability algorithm including an improved parallel network algorithm and an optimal convergence checking method. The simulation software with the spatial parallel algorithm is designed and implemented on a SMP-cluster system. The test cases of national power grid of China show that the optimal computation time of the parallel software is only 38% of the actual dynamic process. It is suggested that the algorithms described in this paper can achieve the super real-time simulation of very large scale power system and make the complex on-line power applications, especially on-line supervision and control for large scale power system, feasible.
