Development and Operation of Software for Controlling the Components of a “Digital” Recloser

This article reflects the experience of development and subsequent implementation into real operation of software for controlling the components of a “digital” recloser manufactured by JSC “Radio and Microelectronics”. The article contains a theoretical part with a description of the principle of using a recloser as an element of 6/10 kV electrical distribution networks digitalization. In addition, in this part, there is a representation of recloser internal structure with a diagram indicating its main functional components. The practical part of the article presents algorithmic and software tools developed to ensure the operation of individual components of the recloser. In particular, the principle of operation of the device for collecting and transmitting data is considered, and the capabilities of the channel-forming equipment for communication with devices of the upper control level are described. For a complete description of the system operation, the article reviews the developed software for personal computers that allows user to remotely download oscillograms from the reclosers under consideration. In conclusion, the experience of real operation of all the developed software is shown by the example of a system consisting of eight reclosers installed in the territory of Marusino, Novosibirsk region, Russia.
