电力调度系统广域分布式代理关键技术

摘要

随着电网一体化运行特征的日益显著,电力调度系统间业务数据交互愈加频繁.当前业务通过各自开发专用的网关程序进行数据传输难以满足未来调度业务的发展需求.本文提出了一种广域分布式代理技术,通过电力调度域名在各调度机构间感知广域分布式代理的位置信息,并结合广域链路复用、负载均衡和代理监控等功能,构建面向互联大电网调度业务的高效、通用的广域数据交互体系.广域分布式代理统一支撑多业务应用的广域数据传输需求、提高了数据传输规模、增强了系统可用性.广域分布式代理在数据传输规模和容错性等方面优势明显,能较好地适应未来电力调度大数据的传输要求.%With the increasing utilization of power grid integration,the data exchange between power dispatching sys-tems has become more frequent.Currently,each application develops its own gateway program to transfer data,which cannot meet the needs of the development in the future.This paper proposes a wide-area distributed proxy technique.It builds an efficient and universal wide-area data exchange system for the dispatching business of the interconnected large-scale power grids by using a power dispatching domain system which detects the locations of the wide-area distrib-uted proxy between different dispatching organizations,along with wide-area link circuit multiplexing,load balancing and proxy monitoring,etc.Wide-area distributed proxy technique meets the needs of wide-area data transmission of multi-purpose applications,improves the scale of data transmission and enhances the usability of the system.The wide-area distributed proxy technique has obvious advantages in the scale of data transmission and fault tolerance,and can meet the requirements of transmission of big data in the future.
