The Design Of Information Management System For Transformer Condition Assessment

Transformer is very important in power system, the safety and reliability of the transformer operation directly relates to the security and stability of the power system. Because regular maintenance existes insufficient maintenance or excess maintenance, condition-based maintenance has become an inevitable trend in the development of power transformer maintenance way,and it has received the widespread concern of domestic and foreign power workers, the problem that using existing transformer state information accurate judgement of the transformer's health scientifically and effectively become an important power system research topic. For timely, efficiently and accurately conducting transformer condition assessment work,it should do all kinds of state information collection, summary and preliminary analysis through network management information system, so building the information management system for transformer condition assessment has the important practical significance.In this paper, based on the theory of grey target and aiming at the characteristics of transformer state information, grey target theory is used into transformer condition assessment,and introdutes the principle of the method and the concrete implementation steps. In view of the current transformer preliminary experiments and running condition,it have chosen the state information that transformer condition assessment required,and the example shows that the method has higher diagnosis accuracy and reliability. Also the paper introduces the theoretical foundation of system development that include ASP.NET platform framework, ADO.NET technology and relational database technology. After the system database design and the function design, with the national power grid transformer status evaluation guideline for the basis, using ASP.NET technology, adopting the B/S structure, using modular design, it establishes information management system for transformer condition assessment. the system can complete the information query, modification and print, and comprehensively judge the run transformer's health,and accurately determine transformer state through the transformer state measure data.it realizes the transformer huge status information science management, and provides technical support for real conditions of transformer condition-based maintenance.
