On-line monitoring model, power grid model and integrated modeling method for on-line monitoring model and power grid model

The invention provides an on-line monitoring model, a power grid model and an integrated modeling method for the on-line monitoring model and the power grid model. Integrated modeling of the on-line monitoring model and the power grid model is achieved through matching between the nid property of a primary equipment asset layer of the power grid model and the equanid property of a monitoring device layer of the on-line monitoring model; an integrated state analysis model based on on-line monitoring information and power grid operation information is established. The integrated modeling method meets the requirements for various integrated analysis application functions of a state monitoring system, and also meets the technical requirements of an integrated power grid operation intelligent system (OS2).
