In the early stage of power system reliability research, society is in a new stage of rapid development. The primary task of power system is to meet the required power generation, and the impact of unreliable power distribution system on users is increasing. Obvious. Based on the Newton-Raphson method, the mathematical reference model of power flow calculation is established. The set of protection components and their corresponding motion vectors are redefined, and the objective function and network constraints are calculated and passed through the countercurrent in the power flow calculation. The detailed overview of transmission, downstream transmission and reliability assessment, combined with the calculation of relevant values in the relevant examples, further validates the characteristics of downstream and countercurrent transmission, providing a numerical reference for future concrete construction.
