电网调度自动化系统发展趋势展望

电网朝着超/特高压、互联大电网的方向发展,而调度自动化系统则朝着"数字化、集成化、网格化、标准化、市场化、智能化"的方向发展.数字化是指电网设备、采集、控制及管理的信息化;集成化强调的是调度中心内部不同系统间的共享和整合;网格化是指在分层分布的调度管理体制下的各级调度中心之间信息的"需则可知"和分解协调控制;标准化包括遵循标准和制定新标准,强调的是通过遵循标准达到系统的高度开放,理想的目标是实现完全的即插即用;市场化是指在电力市场交易环境下的监控分析和控制;智能化强调的是在数据集成化的基础上将电网的分析和监控提升到完全自动和智能的高度.

Development Trend Prospects of Power Dispatching Automation System

With the development of EHV and power network interconnection, the dispatching automation system trends with several features such as digitization, integration, grid technology, standardization, deregulation and intellectualization. The key of digitization technology is the realization of informatization in electric instruments, data acquisition, control and management. Integration technology emphasizes data sharing and data integration of different systems in dispatching automation system. Grid technology can be utilized to implement the incorporation of information saved dispersedly in hierarchical and distributing power dispatching management system. Standardization emphasizes plug-and-play. Deregulation refers to the supervisory control and analysis of trading in power market. Based on data integration technology, power system analysis and supervisory control can be raised to a completely automatic and intelligent level. The technological issues addressed on these features are analyzed in detail and the future development direction of the dispatching automation system is described.
