摘　　要：为了提高县级调度机构电网设备检修任务的管理效率,减少失误率,保证电网可靠、高效地运行,以PI3000平台为基础设计开发了县级电网设备检修工作流系统.系统采用PI3000平台对对象、流程和安全进行动态建模,解决了检修工作流对象的并发访问控制问题,采用XML进行细粒度数据描述,利用PI3000AJAX框架实现了无刷新客户界面.该系统已经应用于江苏省县级调度机构电网设备检修系统等项目中,能够适应电网设备管理数据处理量大、业务流程复杂的特点,运行效果良好.To improve management efficiency of maintenance tasks of county power network equipments, reduce error rate, and guarantee the power network＇ s reliably and efficient operation, an equipment maintenance workflow system for county power network based on PI3000 platform is designed. The platform is used in the system for dynamic modeling of object, process, and security, to solve the problem of concurrency control of the object of maintenance workflow, XML is used for fine granular data description, and the PI3000 AJAX framework is used to implement non-refresh client interface. The system has been applied to the DMIS project in Jiangsu Province and some other DMIS projects. Practice shows that the system satisfactorily meets large volume data and complex business processing of power network equipment management and runs very well.
