The present invention relates to a method and device for generating an engineering topology of a digital substation. The method may include: generating, by a single line diagram generation module, a single line diagram of the digital substation based on input information regarding a plurality of substation component devices and connection relations therebetween; converting, by a topology conversion module, the single line diagram of the digital substation into an engineering topology conforming to international standards by use of conversion conditions stored in a topology component management module; verifying, by a topology verification module, whether the engineering topology is suitable for the digital substation based on the international standards; and generating, by an international standard file generation module, a single line diagram engineering file of the digital substation as a system specification description (SSS) by use of the verified engineering topology.

A stereo x-ray inspection apparatus and a method for forming a three-dimensional image through volume reconstruction of an image acquired from the same are disclosed. The apparatus includes one x-ray generator and two detectors to acquire two images. The x-ray generator and detectors are arranged in the form of a right-angled triangle, to easily achieve mathematical development and analysis. One of the detectors, which does not just oppose the x-ray generator, is movable and rotatable, to acquire images under the condition that only one detector is moved in accordance with the size of an object, and thus to simplify control operation for the apparatus, so that a more accurate image from an object moving at high speed is acquired.
