The basic principle of field circuit coupling algorithm for multi-loop method is studied. In order to improve the simulation efficiency of the system, the iterative mode and distributed simulation are discussed. On this basis, this algorithm is used to simulate the typical extreme fault conditions of a three-stage brushless AC power system. The simulation results show that the co-simulation algorithm based on multi-loop field-circuit coupling has good numerical convergence and can effectively analyze the steady state, transient state and fault state of the power supply system.
