摘　　要： 随着国家经济发展,社会用电负荷快速增长,电网规模越来越大,结构越来越复杂,作为管理和指挥电网运行的调度员在工作中需要掌握的信息也越来越多,掌控电网的难度也越来越大,特别是电网发生事故后,若不能及时处理,很容易发生次生事故,扩大事故影响及范围。 目前,随着电网自动化水平逐步提高,一些新设备、新技术纷纷在电网中得到应用,比方:能量管理系统/(EMS/)、系统监控与数据采集/(SCADA/)、广域动态数据采集监控/(WAMS/)、继电保护信息系统等,这些都为调度员掌握电网提供了工具和手段,促使调度员从经验性人员向分析性人员转变。 本文结合个人工作实际情况,以安徽电网为例,介绍安徽电网目前发展状况,以及自2008年以来安徽省调实施的实时监控及事故告警、辅助决策的应用研究。研究的主要目的是更好辅助调度员监控电网,在电网运行正常时,辅助调度员进行电网实时监控;在电网发生事故时,能通过信息分析,判别故障类型,并迅速告警,同时提供处理措施,供调度员参考,为调度员处理事故提供辅助决策,甚至在条件成熟时,可以闭环运行自动控制电网,实现快速响应,减小事故影响。 With the national economic development, social power load has increased rapidly, grid scale has become more and more large, structure has become more and more complex, as a management and command, the difficulty of the gird management of Dispatchers is greater and greater. Especially breaking down, if dispatchers do not timely processing, secondary accident could happen, that will expand influence. Now, with the automation level gradually improved, some new equipment, new technologies have been applied in the power grid, for example: energy management system/(EMS/), supervisory control and data acquisition/(SCADA/), Wide Area Measurement System/(WAMS/), relay protection information system. These provide the tools and means for the dispatchers to manage grid, and promote the change of dispatchers working methods from empeiria to analyticity. This dissertation, in the case of Anhui grid, introduces the current development of grid, and implementation on the real-time monitoring and accident warning and supporting decision making for Anhui grid dispatchers since 2008. The main purpose of implementation is supporting monitoring grid for dispatchers. In normal, the system assist dispatchers to instantly monitor grid; When breaking down, it will provide supporting decision making for Anhui grid dispatchers.
