现代能量控制中心概念的扩展与前景展望

随着电网互联和电力体制改革步伐的加快，对电网运行的调度和控制提出了许多更新更高的要求，传统的调度中心EMS的结构和功能将发生很大的变化。为适应这一变化，文中认为现代能量控制中心的概念应当扩展，特点是高度的信息化、智能化、集成化和自动化。其功能由安全发展为安全与经济的协调；局部控制发展为全局分层控制；离线分析发展为在线分析；开环控制发展为闭环控制；在线稳态分析发展为在线暂态分析。

CONCEPT EXTENSION AND PROSPECTS FOR MODERN ENERGY CONTROL CENTERS

Interconnection of power network and restructuring in power industry are raising increasingly more new requirements on power system operation and dispatch. The energy management system (EMS) in a traditional dispatch center has been changed a lot in configuration and functions. To adapt the EMS to the change, a concept of modern energy control center is proposed in this paper, which features high-level information, intelligence, integration and automation. The functions of the EMS will be developed from security only to coordination of security with economy, from local control to global and hierarchical control, from mainly off-line analysis to on-line analysis, from open loop control to closed loop control, from on-line steady state analysis to on-line transient state analysis. This paper describes the function extension of the EMS in a modern energy control center and predicts its prospects for development.
