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.

Method and device for generating engineering topology of digital substation

The present invention relates to a multi-pulse HVDC system which is capable of minimizing the number of thyristors by providing a thyristor auxiliary circuit in a conventional 12-pulse thyristor HVDC(High Voltage Direct Current), not using an additional stack of a thyristor and which is implemented based on an auxiliary circuit having a multi-pulse thyristor HVDC system like 24-pulse/36-pulse/48-pulse converters. The multi-pulse HVDC system is characterized in that an upper side thyristor converterand a lower side thyristor converterare installed in a &#x394;-&#x394;-Y transformer, and two current smoothing reactorand a direct voltage dividing condenserare installed between the upper side thyristor converterand the lower side thyristor converter, and two thyristors: Tand Tare connected to one double winding transformer
