Research On Design And Application Of Integrated On-line Monitoring System For Intelligent Transformer

Intelligent transformer is one of the key power equipment in smart grid, the intelligent level is important to the operation reliability and economy of smart grid. Research on the application of integrated on-line monitoring technology for the intelligent transformer is important for ensuring the safe operation of the power system and the maintenance of the transformer. This thesis presents the framework design, development and application of the integrated on-line monitoring system. The main contents of this thesis are as follows:① System architecture and network structure of smart grid are analyzed. The working principle of on-line monitoring for intelligent transformer is presented and the typical application scheme of the integrated on-line monitoring system is presented.② The integrated on-line monitoring device for the intelligent transformer is developed. The operation state of the intelligent transformer is evaluated by many parameters. Therefore, an on-line monitoring method was adopted to develop an integrated intelligent monitoring device by detecting a variety of parameters. It can realize data fusion and improve the accuracy and reliability of the information.③ The software with functions of system generation, adapting to the changes of hardware and real time database was developed to monitor the parameters of intelligent transformer, which realizes the self-diagnosis of the integrated intelligent monitoring device.
