摘　　要：在电力系统的动态稳定在线评估和实时仿真计算中,并行处理是一种非常有发展前途的技术。许多种类的并行算法已被提出,并在不同类型的并行计算机上实现。由于具有性价比高、升级和扩展性能好的特点,PC机群并行计算机吸引了越来越多的注意力。本文综述和讨论了几种机电暂态并行算法,特别是在PC机群上实现这些算法的有利和不利条件。本文讨论的并行算法包括:网络分割、线性方程并行求解、牛顿类算法和一些时间并行算法。Parallel processing is a promising approach to on-line assessment of power system dynamic security and its real-time simulation. Many kinds of parallel algorithms have been put forward and implemented by various types of parallel computers. Because of its advantages such as high performance-to-price ratio, easy to update and good expansibility, more and more attention is being paid to personal computer (PC) cluster for parallel processing. Here several parallel algorithms for electromechanical transient stability calculation, including the network partition, parallel solution of linear equations, algorithms of Newton types and parallel-in-time algorithms, are summarized and assessed, especially the favorable and unfavorable conditions to implement these algorithms by PC cluster are concerned.
