Specialists of Rosseti Centre - the managing organization of Rosseti Centre and Volga Region are completing the design of distributed automation in 30 pilot Digital Distribution Zones.
“The implementation of distributed automation is a key element of our technological breakthrough and an important component of the first stage of the digital transformation of the electric grid complex. The use of modern equipment will, in particular, significantly reduce the time required to eliminate technological violations and significantly increase the reliability of energy supply to consumers,” says General Director of Rosseti Centre - the managing organization of Rosseti Centre and Volga Region Igor Makovskiy.
The goal of creating distributed automation is to reduce the SAIDI and SAIFI by increasing the observability and automation of locating faulty sections of distribution grids.
The project provides for installation of 6-10 kV switching devices (reclosers), remotely controlled load switches, disconnectors, and short circuit indicators. All new equipment will be integrated with the Unified Control Centre.
Distributed automation is one of the core technologies of the Smart Grid. Its implementation will allow, first of all, to increase the flexibility of distribution grid schemes, which will make it possible to selectively identify and locate faulty sections, while maintaining maximum energy supply to consumers. This task is performed by controlled switching devices of various types having the function of remote control and data transmission. The project completion date is the end of the first half of 2020.
The concept of digital transformation, adopted in 2018, provides for the transition to a new principle of operation of the electric grid infrastructure by 2030. The implementation of the concept projects will reduce costs of maintenance, repair and operation of facilities, decrease grid losses, significantly reduce the number and time of eliminating technological violations and, therefore, improve the quality and reliability of power supply to consumers throughout the country.
A Digital Distribution Zone is a service area of electric grids with a high level of automation, providing real-time observability and allowing to realize the functions of self-diagnosis and self-healing, as well as smart metering of electricity.
