The invention discloses an abstraction compression method for a power transmission network view model. The power transmission network view model is abstracted into three types of models including a voltage class model, a regional web model and a contact relation model. Power grid local models corresponding to the voltage class model, the regional web model and the contact relation model are obtained by means of a compression algorithm, a compression rule is that for the voltage class model, a device object with selected voltage class is a whole, an external object is compressed to a boundary, a boundary object and external important channels are retained; for the regional web model, the outside of a selected region object is compressed to the boundary, a boundary object and external important channels are retained; for the contact relation model, the outside of a selected contact relation object is compressed to the boundary, a boundary object and external important channels are retained. The abstraction compression method well meets the requirement on an abstraction model corresponding to the power transmission network view corresponding to a macroscopic-microcosmic decision-making view required by a power transmission network operation decision.
