Coal-fired Power Plant Operation Management System Design And Implementation

The sharp conflict in the market has set an even higher demand for the power plant including:to strenghten the analysis of the forecast and control of the cost, as well as reduce the wastage and lower the costs. Based on this we have developed multi-platform business management major subsystems-operation management system, the system covers planty of the informations that which are needed to be monitor in the power plant, in order to help the operator control the operating state in time, to provide managers with more kinds of decision support information and a clear cost basis.In the article, the author first analyzes the development background of the system and the present situation of the development of the power plants' monitoring control system, also gave a brief overview of the main issues that need to be solved of the system along with the explaination of the great contribution made by the major technology and system to the research in the area of power plant. Strict use of Unified Modeling Language UML to design the system. System requirements analysis, the author uses the use case diagrams and activity diagrams to clearly express the system users' the main demand in the architecture design part, the writer use the system sequence diagrams and deployment diagrams of system flexibly as well as in the architecture, in detailed design of the system,the writer used the relationship class diagram to express the static structure, with the state diagram to the dynamic structure of the system representation. Implementation part of the system, the system used J2EE architecture, integrated under the multi—platform business management of Huadian Group, the user could enter the system as long as inputing the address in the IE address bar, this reflect the quick and convienence in interviewing and also easy to promote.The system gathered all of the functions as an organism, incuding the operation of the core and auxiliary equipment, switching test, maintainance of the equipment togather with starting/stopping of the generating unite and the amount of generation, cost of fuel and oil for the first time. This system has formed a complete real-time monitoring system for operation, it has realized integratted innovation. Physical isolation devices in isolation, the first time developed a software package console monitoring and data analysis capabilities to monitor the interface to address the high security zone in the operation and management system features low-security zone in the high quality of the management side of the mirror sync display problem; achieved by running the management system to achieve a large number of digital information production and management, quantitative, enabling managers to run the unit any time, any part of the operation in a timely accurate and objective understanding of a variety of timely decision making so that the level of enterprise information onto a new level.
