摘　　要：给出了基于工作流技术的电力系统检修管理过程的全新建模方法及执行算法。以这种面向过程的系统集成技术为基础,可使检修管理信息在调度与运行、检修部门间自动流转与处理,实现检修管理过程的自动化。提出了基于任务的建模思想,以基于Petri网的扩展P/T系统为工作流模型。给出了工作流的定义方式及检修管理过程的建模原理和步骤。系统底层实现基于共享文档数据库及邮件传递技术,具有分布异构系统的互操作能力。给出的方法已成功应用于供电局检修管理系统中,验证了其可行性及有效性。Based on workflow technique, a new modeling method and algorithm for power system overhaul and repair management process are presented. Using the process-oriented technique, the overhaul and repair management information can be processed in computer network automatically. A task-based modeling idea is advanced, which takes the expanded P/T_system based on PetriNet as a workflow model. With the introduction of the workflow's definition, this paper explains the modeling principle and the approach of the overhaul and repair management process. The substrate support of the system is founded on the shareware document database and mails transfer technique, so the system has a interoperate ability to the distributed heterostructure environment. The system has been successfully applied to the overhaul and repair management information system (MIS) project of a electric power supply company and is proved to be feasible and effective.
