The invention belongs to the technical field of electrical equipment fault diagnosis, and particularly relates to an MOA energy absorption calculation method based on a modular circuit breaker, which comprises the steps of circuit breaker topological structure design, topological parameter mathematical model and MOA energy absorption calculation. Based on the characteristics of rapid adjustment, small occupied area, high voltage grade and the like, the calculation method for the MOA energy absorption of the circuit breaker can control the size of D, and can be matched with a direct current circuit breaker to carry out protection action. When the maximum breaking current of the direct-current circuit breaker is fixed, the action time of the circuit breaker can be prolonged by reducing D, and when the action time of the direct-current circuit breaker is fixed, the maximum breaking current of the circuit breaker can be reduced by reducing D. 本发明属于电气设备故障诊断技术领域，具体涉及一种基于模块化断路器的MOA能量吸收计算方法，包括断路器拓扑结构设计、拓扑参数数学模型以及MOA能
