The invention provides a process scheduling method for online network analysis distributed computing of a large power grid. The method comprises the steps that a user side process scheduling client side sends a computing request to a cluster process scheduling server and a wide-area process scheduling server of a coordinating management side; the cluster process scheduling server of the coordinating management side distributes a certain node in a cluster as a process scheduling server side to execute process scheduling service; all node computing service units initiate registering to the process scheduling service unit server side; after all the computing service units of the coordinating management side finish registering, process service state monitoring threads are started; the follow-up steps of a coordinating side and the steps of a coordinating management side are the same. According to the method, all automatic scheduling systems participating in distributed computing are equal, meet the integrated computing requirements of superior scheduling and meanwhile support integrated computing of subordinate scheduling.
