The present invention discloses a physical loop fast connection method based on a template base. The modeling of the physical loop template is performed according to the devices and the physical loops of each type of internals in the practical engineering to form a physical loop template base; and the physical loop template with the corresponding type of the internal is selected in the physical loop template base and the physical loop template is analyzed when the secondary loop design of the practical engineering is performed to realize the mapping of the devices and the physical loop in the physical loop template in the practical engineering and complete the physical loop design of the practical engineering. Through the building of the physical loop template and the typical design case of covering each voltage grade, the instantiation of the physical loop template is performed to rapidly complete the secondary physical loop design of the transformer substation so as to reduce the error rate generated in the artificial physical loop design process and improve the designer's efficiency in the physical loop design process.
