摘　　要：随着浙江电网GIS建设不断推进,系统性能需求得到越来越广泛的重视。针对电网GIS客户端登陆时间过长的问题,提出一种基于本地缓存技术的电网GIS性能优化方法,设计新增本地硬盘缓存电网资源空间数据功能,并对本地序列化缓存、内存数据增量更新、本地缓存处理过程等关键技术点,展开了分析研究。最后,将该技术应用于配电GIS客户端,测试结果表明,通过从本地缓存加载电网数据方式,极大地提高了登录速度,取得了良好的应用效果。With the construction advancement of Zhejiang power grid GIS, the system performance require- ments are increasingly widely recognized. Aiming at overlong login time of GIS client, the paper proposes grid GIS optimization method based on local cache technology. New local hard disk cache grid resource spatial da- ta capability is designed, and local serialization cache, update of memory data growth volume and key tech- nical points like local cache processing procedure are analyzed and investigated. Finally, the technology is applied in power distribution GIS client, test result of which shows that by loading the grid data from the lo- cal cache, the login speed is greatly promoted and good application result has been achieved.
