Study on the Key Technology of Intelligent Transformer

The development of smart grid puts higher requirement on the intelligentization of high-voltage equipment including transformers. At present, the intelligentization of transformers is mainly realized through intelligent components. The combination of intelligent components and transformer can realize the measurement, control, calculation, inspection and protection of the transformer. This paper detailedly described the hardware design framework and software function modules of transformer intelligent components, as well as the expert diagnosis system applied to transformer intelligent components. The intelligent components designed by this paper have been successfully applied to 220kV intelligent substation, which is operating stably and reliably. This can promote the development of intelligentized primary power equipment and smart grid as well.
