Modeling method and simulation method for monitoring signals in electric power dispatching simulation training system

The invention discloses a modeling method and a simulation method for monitoring signals in an electric power dispatching simulation training system. The modeling method comprises the following steps of: performing data processing on all equipment, faults and monitoring signals in the conventional power grid dispatching system serving as a model to form fault data units and monitoring signal data units which are in one-to-one correspondence to the faults and the monitoring signals; counting, arranging and classifying the fault data units and the monitoring signal data units to form a fault data repository and an unlabelled monitoring signal data repository; matching the monitoring signal data units in the monitoring signal data repository with the fault data units in the fault data repository by using equipment information as the corresponding standard; and marking a trigger label to be searched and screened and the like on each monitoring signal data unit. The modeling method and the simulation method have the advantages that secondary equipment monitoring signals can be effectively simulated, the simulation authenticity and recoverability of power grid monitoring signals are achieved to the greatest extent, and an actual effect of simulation training is greatly improved.
