Design And Implementation Of Shanghai North Power Company Special Running And Maintaining Management System

This thesis states design and implementation of Shanghai North Power Company's special running and maintaining project management system. This system is one of important components of the enterprise's production maintaining information system which provides dedicated support to special types of operational services.In this thesis the system development based on software engineering principles and techniques is constructed around the current requirements for dedicated maintaining operations. The software's functional requirements is modeled with detailed analysis about this system's functions of middle voltage and high voltage reliability management, line-loss-rate management and powerless management with the corresponding use case models in accordance with the company's actual operational situations. The thesis presents this software's design scheme which setups the client/server mode distributed system architecture and describes the major modules. Each module is designed by means of object-oriented methods and techniques for its internal structure. The whole system database design is presented with relational data model. The application system is programmed with Java programming model and the integrated database server is Oracle. This thesis describes the major programs'implementation methods and briefly states the system's test methods and results.This software provides comparatively complete informationized solution to the current dedicated maintaining operations while it has appropriate extension capability to integrate new dedicated tasks and requirements. This system has now been on line in combination with the general maintaining management system to provide complete information support to the company's electrical power supply maintaining tasks, strongly guaranteeing the operation's accuracy, timeliness and information completeness.
