Abstract:

为实现大规模配电网的实时分析计算,构建了基于数据级任务分解的配电网分布式并行计算平台。结合配电网运行结构和设备配置,以配电网馈线作为分析单元,采用数据级并行计算方式对配电网计算任务进行分解。配置管理模块、实例、执行端和客户端4个子系统,分别实现任务生成、任务分解、任务派发以及子任务计算等功能,形成分布式并行计算平台框架。引入消息中间件ZeroMQ技术,采用不同类型套接字的组合实现分布式系统内部的N-N高效通信及与外部系统的数据交互。为验证该平台的实用性及并行计算性能,在平台上实现了山东省某市的城市配电网全局状态估计的分布式并行计算。算例分析表明在配电网节点达到一定规模时,采用该平台进行分布式并行计算具有明显的速度优势。
