The invention relates to a service-oriented power distribution network information physical system, consisting of a device layer, a support layer, an application layer and an interface layer, wherein the device layer, the support layer, the application layer and the interface layer are separately communicated to one another through an IEC61968 standard interface; the device layer, the support layer, the application layer and the interface layer can serve as service users. According to the service-oriented power distribution network information physical system provided by the invention, the power distribution network information physical system is integrated based on the encapsulation of components or elements at specific operational levels and aiming at the interfaces and associations of services or the components, and a composite multifunctional application system can be formed through the step-by-step assembly and process planning of application service components.
