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。
The dynamic monitoring of power system has put forward new requirements for man-machine interface of energy management system (EMS). Based on information theory, this paper analyzes the process of human-computer interaction in EMS and proposes an improved dispatcher information analysis model. The model can reduce the workload of dispatchers and improve work efficiency. In order to realize this model, it is proposed that EMS should adopt the new framework of power system information visualization. The power system information visualization under the new framework includes two-dimensional space and three-dimensional space. The relationship between 2D and 3D visualization is analyzed. The method of visualizing power system in 3D space is expounded, and the validity and superiority of voltage monitoring in 3D space are verified.
