摘　　要：分析了在我国电网规模不断扩大、计算机及通信技术快速发展的形势下，电网调度中传统模拟屏的局限性，介绍了投影墙系统的优越性及北京供电局调度投影墙系统的结构和功能。为了弥补原产品功能的不足，作者在工作站上开发了一些软件功能模块，使投影墙系统与EMS有机地结合起来，从而充分发挥投影墙系统的多用途功能，并允许多工作站多调度员操作。这些模块还具有日志管理、操作权限管理、上墙内容限制、屏幕亮度控制和多机容错等多项功能。This paper analyses the limitations of traditional mimic board and the advantages of projection wall in BeijingPower Supply Bureau's dispatching system are introduced. In order to remedy the imperfection of the original functions. theauthors develop some new function modules to combine the projection wall with EMS. The irnproved function modules canbring the multi-function capabilities of Projection wall into full play so as to meet the requirernents of EMS applications. Themulti-substation and multi-dispatchers operation can also be realized. These modules have functions such as log management.operation authority management. on-wall application limit. brightness control and fault tolerance with multi-machines.
