摘要: |
针对电力系统安全稳定分析分布式计算的应用现状,基于异步并发和工作流的思想,提出了一种适应于粗粒度算例并行的电力系统安全稳定分析多层次并发计算框架。通过多数据断面并行和多应用功能并发,在不改变安全稳定分析程序算法逻辑的前提下,实现对不同断面下多个应用功能的计算任务异步并发调度管理,有效提高了计算资源的利用率。基于过程定义方法对安全稳定分析应用功能进行统一封装,满足不同运行场景下安全稳定分析计算流程的定制化需求。该技术已在多个省级及以上电网安全稳定综合防御系统中得到应用,验证了该方法的有效性。 |

Abstract: |
In order to meet the distributed computing demands of the power system security stability analysis, the multi-layer asynchronous concurrent computing architecture for power system security stability analysis coarse granularity paralleling which is based on asynchronous concurrent and workflow technologies is proposed. Through with multi-scheme and multi-function asynchronous concurrent computing mechanism, multiple functions tasks of different periods data are unified dispatching management for improving the utilization of computing resources without modifying the algorithm of security and stability analysis program. In order to satisfy the custom requirements of calculation procedure in different scenarios, all functions are unified encapsulation based on the process definition method for the power system security stability analysis functions. The application in power system security and stability integrated and coordinated defense systems of provincial and above power grid demonstrate the validity of the method.
