Structural diagram of the prototype of a digital transformer substation

Digitalization, automation of rural electrical networks is not feasible without the development of appropriate solutions for 10/0.4 kV transformer substations. Automation tools should ensure the observability and controllability of transformer substations of this voltage class, the creation of digital transformer substations. In particular, the ability to remotely determine the position of switching devices, the reasons for their shutdown, the ability to control some switching devices should be provided. It is also necessary to ensure the performance of functions for monitoring unauthorized voltage supply and preventing reverse transformation, monitoring the parameters of the operating modes of the electrical network at different points of the transformer substation and a number of other functions. The implementation of solutions for digitalization and automation of 10/0.4 kV transformer substations requires the creation of their prototype to conduct the necessary experimental studies and develop automation algorithms. The article presents the developed prototype diagram of a 10/0.4 kV digital transformer substation.
