电网集成调度技术

Integration technique for power network dispatch systems

通过对现代化电力供电网络调度现状与需求的研究,提出了现代化电网集成调度技术方案;通过构建基于数字投影单元的无缝拼接显示墙系统,将调度计算机的分辨率提升到 6 400×3 072(色彩数16 M)或更高,由此实现了电网一次系统图、SCADA系统、视频监控系统、MIS系统等的集成调度操作. 图形快速刷新技术保证了巨型分辨率下的矢量图形的实时变化,使调度员对整个电网联络情况一目了然,能够迅速准确地掌握电网动态变化信息,使调度操作更加安全可靠.

The modern technique of integration of electric power network dispatch systems is presented in the paper. The display resolution of the display server is promoted to 6 400×3 072 (16 M colors) or higher by constructing the seamless mosaic display wall system using the projection display units with the technology based on digital light processing. Then the power network drawing, SCADA system, video supervisory system and the MIS are integrated and displayed on this display wall. According to the resolution, the power network dispatch system is designed with whole vector and real-time technology. It makes dispatcher grasp the information of power network accurately and quickly, and makes dispatch operation safer and more reliable.
