The circuit breaker was the most important control and protection device in the power system. However, the switching state was only simply represented by most of the existing circuit breaker models, so a circuit breaker based on dynamic arc was established. Firstly, the selected arc model was analyzed to obtain the required parameters. Then, the circuit breaker simulation model was built in PSCAD/EMTDC. The algorithm was programmed for the arc model in MATLAB, and MATLAB was called by special interface in PSCAD. Through the simulation research and comparison, the voltage and current of the breaker when the fault was cut off was basically consistent with the theoretical analysis. The correctness of the circuit breaker model was verified, which showed that the design model had a certain reference.

Key words: circuit breaker, PSCAD, MATLAB, arc, Cassie model, dynamic resistance
