Design And Implement Of Dispatching Management Information System In Power Net Based On Three Tiers Architecture

With the uninterrupted development of the Power Network, the claim of informational management is raised in power fields. The maturity of database technology and the wide application of Internet technology lay the solid foundations for the accomplishment of Management Information System.This p aper i ntroduces t he d evelopment o f t he architecture o f M anagement Information System, and then compares the three-tired architecture of Client/Server and Browser/Server. According to the special requirements of the Power Network Dispatching Management Information System, a hybrid architecture based on C/S and B/S is presented; the key technologies of the architecture are analyzed; the design methods are determined: Delphi implements the C/S architecture and A SP i mplements the B/S architecture. The knowledge concerned is introduced briefly.In this paper, the demands of the Dispatching Center are analyzed in detail, and then the frame of C/S and B/S architecture; the security competition of the system are designed; transference and storage of the prompt data are accomplished. The main components and the functions on client are given, the result of analysis and design are presented. Finally, the strong and weak properties of the system are concluded and the direction to improvement is pointed out.After the system has been established, it runs stably and the state is well. There are efficient manage ability, friendly mutuality, good adaptation and expansionary on it. It has great effects on rising the ability for supervisory and management of power system. It provides the accurate and comprehensive information; the security and stability of the power network are guaranteed.
