本文提出了一种用于电力系统安全评估的事故分析并行处理方法。完整的交流潮流分析是为每个应急和违反母线电压和线路流量进行评估。所有可能的线路中断都被考虑在内，以避免忽视某些关键情况。采用并行处理来提高执行速度。通过在处理器之间共享每个偶然事件来实现并行性。所提出的方法在一个Linux集群中实现。通过消息传递接口（MPI）进行数据通信。并行性的有效性证明了标准IEEE系统上进行权变分析。该算法的性能进行了分析，在计算速度和效率的顺序方法相比。
This paper proposes a parallel processing approach to contingency analysis (CA) for power system security evaluation. Full AC power flow analysis is done for each contingency and violations of bus voltages and line flows are evaluated. All possible line outages are considered to avoid overlooking of certain critical cases. Parallel Processing is employed to increase the speed of execution. Parallelism is achieved by sharing each contingency across processors. The proposed methodology is implemented in a Linux Cluster. Data communication is performed through the Message Passing Interface (MPI). The effectiveness of parallelism is demonstrated by performing contingency analysis on standard IEEE Systems. The performance of the algorithm is analyzed in terms of computation speed and efficiency in comparison with the sequential approach.
