Modern App.roaches to Design of Traction Power Network Facilities Using BIM Technology

Optimisation of architecture and construction projects of power supp.ly systems can be achieved with the help of BIM technology, which allows creating a single information model of interrelated processes. It permits to automatically prevent many design mistakes, and BIM makes analysis of project decisions made easier and more visual, significantly improving quality of design, and working documentation.BIM technology is a modern app.roach to design-build-operate cycle. We can say that BIM is organised information about an object, used both at the design and construction stage, and during its operation and dismantling.A single information space, that is a database containing all information about the technical, operational, energy and other features of the facility constitutes an important component of this technology. Due to an accurate and detailed development of the model, this technology makes it possible to carry out various calculations and analyses. A computer model of a new object created during the design process contains all the information about it. With BIM design, a designer at any level has the opp.ortunity and direct need to think about an object as about a holistic model, in real time, and in conformity with its economic component.Competent use of software products for development of BIM models, as well as of the visual programming environment and of the subsequent execution of working documentation, significantly reduces design time and the number of errors. Thus, the costs and time for correcting errors are minimised.The above features of BIM technology allow full use of its advantages when adopting digital modelling in construction of railway power facilities. This process also offers an opp.ortunity to directly relate development of engineering design solutions and electrical engineering calculations within simulation modelling.The objective of the study was to analyse of practical adaptability and features of adoption of this technology while designing catenary. Generalised expertise served to demonstrate key points in implementing relevant information environment, features of development of digital twins of objects of power supp.ly infrastructure and of their operation.
