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.
