One of the first digital substations (DSS) in Russia supplying oil and petroleum products to pipeline transportation facilities has been put into trial operation at Desna oil pumping station (PS) of Bryansk Regional Directorate of Transneft Druzhba.
The research and development is being implemented as part of a pilot project of Transneft. This project is unique for its technical solutions not only for Russian, but also for the global electric power industry. It is supposed to test two types of DSSs of 110 kV voltage classes in order to compare their technical and economic performance: a DSS with a decentralised structure of automation system will be tested at Transneft Druzhba, and a DSS with a centralised structure of automation system will be tested at Transneft Siberia.
All information exchange processes between the elements of the DSS and external systems are carried out in digital form. Optical current transformers and electronic voltage transformers are used as the main source of measurement of electrical values.
Following the results of the pilot projects, an assessment will be made for the real possibilities of digital technologies in supplying power to pipeline transportation facilities, the potential for their further application will be studied, a feasibility study will be carried out, and generic solutions for Transneft system’s facilities will be developed.
