The increasing size of the power grid and the growing demand for grid security have put forward higher requirements for the performance of power protection systems. Edge computing method is selected as the power relay protection algorithm to design the system framework of relay protection. Meanwhile, the relay protection algorithm based on sinusoidal function model is introduced to calculate the RMS value, phase difference and circuit parameters of the input signal, thus completing the design and construction of the intelligent power protection system. Build the collection process of basic power consumption information of users, and obtain the power consumption pattern of users. On the basis of users’ basic power consumption information, artificial intelligence technology is used to automatically predict the grid load, analyze the power stability, and realize the intelligent control of power protection strategy. Compared with similar systems, the intelligent power protection system designed in this paper maintains the o
