Claim of US Patent No. 10,169,528

1. A method of controlling and/or monitoring a digital substation, the method comprising:automatically generating a computer-readable engineering topology of a digital substation by:
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 computer-readable single-line diagram engineering file of the digital substation as a system specification description (SSS) by use of the verified engineering topology;
providing the computer-readable single-line diagram engineering file to a computerized supervisory control and data acquisition (SCADA) system; and
controlling, by the SCADA system, the digital substation,
wherein converting the single-line diagram into an engineering topology comprises establishing connection relations between connection nodes (CN) and terminals for individual objects included in the single-line diagram of the digital substation, and
verifying whether the engineering topology is suitable comprises determining whether an isolated object is present among objects contained in the single-line diagram of the digital substation based on a determination that an object is not linked with any other object.
