【摘要】 电力系统动态监视对能量管理系统(EMS)人机交互界面提出了新的要求。以信息论为依据,分析了EMS人机交互的过程,提出了改进的调度员信息分析模型。该模型能减少调度员的工作量,提高工作效率。为了实现该模型,提出了EMS应采用电力系统信息可视化新框架。新框架下的电力系统信息可视化包括二维空间和三维空间两个部分。分析了二维和三维可视化的关系,阐述了三维空间下电力系统可视化的方法,并验证了三维空间电压监视的有效性和优越性。更多还原

【Abstract】 Power system dynamic monitoring has raised new requirements on the EMS man-machine interface. The process of man-machine information interaction is analyzed with the information theory. An improved model for analyzing information from the dispatcher is put forward, which can reduce his workload while increasing his efficiency. In order to realize this model, it is proposed that the EMS adopt the new framework of power system visualization made up of two parts, one in two-dimensional space and the other in three-dimensional space. The relationship between the two parts is discussed and the effectiveness and superiority of power system visualization in three-dimensional space is presented and verified.更多还原
