Research On Electric Enterprise Application Integration

In recent years, the enterprise informationization in our country has matured, many industries have produced great results after 20 year's informationization construction, But "information isolated island" gets more and more serious with the fast development of informationization.In order to solve the problem of "information isolated island", the IT industries put forward many theories and solutions. These theories infiltrate and effect together and people couldn't make a distinction and select suitable solutions.With the embedding of electricity enterprise reform, the mode of commercialization operation gradually comes into power system. In this new operation mode, the Multiple heterogeneous electricity information system will help the successfully operation of each electric power information subsystem, and it can make the whole electricity power system expansible, transplantable, maintainable. Electric power system's integration is the result of information age, and the necessary requirements of electric power system's taking part in market competition. The system's extension and upgrading and maintenance design is the most important part of electric power system design.As a big developed state-owned enterprise, Longkou power supply company also faces the problem of "information isolated island". For example, there have Supervisory Control And Data Acquisition (SCADA), Management Information System(MIS), Geographical Information System (GIS), Load Control System and Consumer Management System etc. These systems are affiliated to productive technique branch, consumer management branch and information management branch, respectively. Each system has great independence and autonomy. Their resources can't be shared and exchanged, that result in poor application function of these systems. The company has reached a consensus on solving this problem. The key to solving the problem is to analysis, select and professional designed "Enterprise Application Integration" program.Application integration integrates all the data of information system without affecting the function and performance of the existing system, so as to expand the system functions for data sharing, reduce investment, improve the operation efficiency of equipment, as well as lay a good foundation for the business integration of the information system.Enterprise application integration requires a comprehensive understanding of business processes, and a comprehensive control of information systems resources allocation, information flows and various feature and function designs.This article is based on the characters of the power supply company and introduce the application integration method of the power information system, including requirement description, business model building and the specific application scheme. The specific application part introduces the building process of data center and data extraction, including the database design methods, principles and specific applications.
