电力调度分布式工作流设计与实现

Design and Implementation of Distributed Workflow for Electric Power Dispatching

电力调度工作流具有广域传输、安全以及系统集成等特性。文中分析了电力调度流程的特点,以实现广域分布式调度流程为目的,基于智能电网调度技术支持系统平台提出了一种与邮件服务相集成的分布式工作流设计方案。流程文件使用高效的E语言描述,工作流服务调用消息邮件服务将流程文件以邮件形式传递,目标端工作流服务收取邮件并进行解析,实现分布式的流程流转。对该机制进行了详细阐述,说明了服务总线与其他服务或系统集成的原理,并根据设计予以实现。安全校核业务应用证明,此机制满足了电力调度流程跨系统流转和分布式服务的需求,具有应用价值。

In view of the wide area flowing,security and system integration characteristics of power dispatching workflows,an analysis is made of the characteristics of the power dispatching process.For the purpose of implementing the wide area distributed dispatching process,a distributed workflow design integrated with the e-mail service based on the intelligent power dispatching technology support system platform is put forward.The workflow service transmits the process file described with highly efficient E language as an e-mail by calling message e-mail service.The destination workflow service downloads and passes the e-mail so as to implement the distributed process flowing.The mechanism is discussed in detail,the principle of integration between the service bus and other services or systems is demonstrated,and the integration is implemented according to the design.Application in security checking shows that the mechanism is of applicable value for its satisfaction of the requirement of distributed service while the power dispatching process is flowing among systems.
