The invention relates to the field of electric system scheduling automation, in particular to a steady state monitoring method based on power grid events. The method includes the following steps of firstly, judging the power grid events; secondly, classifying the power grid events; thirdly, uniformly sending the classified power grid events to an event channel on a message bus, and transmitting the classified power grid events to an event receiving end; fourthly, automatically triggering a functional module to conduct analyzing and calculating, and analyzing the degree of influence of the events on grid operation. According to the method, the calculation efficiency of each application module in the scheduling automation system is improved, each application module does not only conduct cycle calculation any more, a computer can be instantly turned on when the power grid events occur, and running conditions of a power grid can be more intuitively and rapidly monitored by yardman.
