| Abstract: | A microcomputer-based transformer protection device based on the fault component is designed in this paper. Compared with traditional differential protection based on all components, differential protection based on the fault component has its advantage. In view of the development of the integrated automation of substations,the interface of the CAN bus is provided for the connection of protection devices. The hardware design of the presented protection device, the theory of protection and the algorithm of signal processing are introduced in the paper. |
