The invention discloses a micro-grid real-time simulation method for processing multi-break switches of power systems. The method comprises the following steps of: judging a time period of an action moment of an electronic power switch, and calculating a correct switch time point by adoption of a linear interpolation method; if a plurality of switch motions exist in a certain time step length, selecting the average value of switch motion time points as a uniform switch motion point in the step length, and calculating a system state variable at the moment by adoption of an interpolation method; and introducing a segmented function parameter and calculating an integral weight according to a specific position of a switch motion average moment in the step length, after one step or two steps, carrying out Euler's integral to the next whole step time point to obtain a correct network topology and a correct system initial value at the moment, and converting to an implicit trapezoidal integral method to complete global calculation. The method disclosed by the invention can be used for effectively solving the traditional difficulty that the simulation efficiency and correctness are influenced by the high-frequency change of the system topology as multi-break switches occur in the same step length during the electromagnetic transient real-time simulation of the power systems.
