Yang Qixin's main achievements:

Yang Qixun creatively solved the world-class major problem of distance protection for extra-large resistance grounding fault, and presided over the "Seventh Five-Year Plan" major scientific research project of 500KV line microcomputer protection device. Yang Qixun's invention, creation, popularization and application made the history of China power system automation span the era of integrated circuits and directly enter the era of microcomputer application.

1994, Yang Qixun founded Sifang Company, pioneered the single-chip microcomputer technology without bus chip, greatly improved the anti-interference performance of microcomputer protection devices, and applied the latest international technologies such as computer, network communication and digital signal processing in the 1990s to relay protection devices, making them not just independent devices, but intelligent units in the whole power system information processing process, greatly saving the cost of substation occupation and cable laying.
