Problems solved by technology

[0003] However, the simulation implementation method of secondary circuit simulation fault troubleshooting in the power system in the related art uses real base point protection equipment and needs to install a power amplifier, which not only cannot realize the rapidity of secondary circuit modeling, but also leads to relatively high investment in equipment. Large, and with the development of technology, it is difficult to upgrade and transform hardware equipment

In addition, the real equipment can only be aimed at specific relay protection devices, and its versatility is not high. It can only be demonstrated by teachers or train students one by one, resulting in low training efficiency
