配电自动化系统中基于多态的事故追忆实现

Implemention of accident recalling based on multi-context in distribution automation system

事故追忆是配电自动化系统中一项非常重要的功能。通过此功能,可以将保存的事故数据进行重演,反映出事故前后一段时间电网的实际运行状态,方便调度人员分析事故原因,调整电网的运行方式。随着智能电网的全面建设,对配电自动化主站系统的要求越来越高,需求越来越复杂,传统的事故追忆功能已经满足不了客户的实际需求。本文基于多态的思想,提出了软件的架构设计,并介绍了主要模块的功能。本成果已在多个工程现场得到实际应用,将传统的事故追忆功能提升到一个新的高度。

Accident recalling is a very important function in distribution automation system. Through this function, the system can replay accident data, and reflect the actual running state for a period of time before and after the power grid accident. Dispatcher can easily and effectively analyze the cause of the accident, and adjust the power grid operation mode. With the full implementation of smart grid construction, the request for master station system of distribution automation is getting higher and higher, and the requirements become more complex, traditional function of accident recalling can no longer meet needs of customers. In this paper, based on the idea of multi-context, the software architecture is put forward, and the function of main modules are introduced. The achievement have been applied to many projects, it elevates the traditional function of accident recalling to a new level.
