| 摘要: |
| 基于MPI实现了一种基于用户自定义建模思想的含有大量继电保护和安全自动装置的连锁故障并行仿真软件。软件首先采用面向对象的用户自定义建模方法，完成大量继电保护和安全自动装置建模；然后采用分网并行和分组并行计算技术，将大规模电网进行网络分割，分配给子网进程；将大量继电保护和安全自动装置模型进行分组划分，分配给外接进程。任务分配后的数据被提交到并行集群上，执行连锁故障的并行仿真。由于子网进程和外接进程由不同的CPU并行计算，程序效率得以提高，能在用户可接受的时间内完成大电网的连锁故障仿真。 |

| Abstract: |
| A cascading failure parallel simulating software which can simulate working of many relay protections and automatic safety devices in power system is implemented based on MPI and user-defined modelling technique. First, by designing user-defined modeling approach using object-oriented method, modeling of many relay protections and automatic safety devices is completed. Then using parallel computing techniques of splitting power grid and grouping models, the large-scale power grid network is partitioned into several subnets assigned to these processes named subnet-process; and the grouped models for relay protections and automatic safety devices are assigned to these process named external process by group. The data after splitting grid and grouping models are submitted to the parallel cluster and the parallel simulating for cascading failure is starting. Because the subnet-process and external process are executed in parallel by different CPUs, simulating efficiency can be improved, and cascading failure simulating can be completed within an acceptable time of users. |
