Results of development and experimental studies of the storage complex with the energy storage unit SPENE-1

The RELEVANCE of the study is to develop a controlled storage complex (SC) of electrical energy for modern distributed energy based on advanced innovative technologies. OBJECTIVE. To conduct experimental studies, confirm the main technical solutions incorporated into the SC design and develop design and technological documentation (DTD). METHODS. When solving the tasks, experimental methods were used to confirm theoretical studies and calculations of SC units and elements, implemented by MatLab®. RESULTS. The article describes the relevance of the topic, the ways and stages of developing the SPENE-1 SC energy storage device. The work was carried out in three stages. At the first stage, the functional structure of the storage complex, a mathematical model of the storage complex operation as part of an electrical network, methods for calculating parameters and controlling energy flows in electrical networks of various topologies, as well as the ECD for an experimental sample of the storage complex and the control system were developed. At the second stage, an experimental sample of the storage complex control system was manufactured and the experimental sample of the storage complex control system was adjusted and tested. A program and methodology for testing an experimental sample of the storage complex, including the control system, have been developed; methodological materials for conducting comprehensive tests of experimental samples and working documentation for upgrading the test facility have been prepared. At the third stage of the work, the following was performed: a) assembly, adjustment and testing of the NC for conducting joint comprehensive tests of experimental samples; b) determination of the optimal parameters of the NC, the main characteristics and the range of their changes; c) experimental tests of the critical parameters of the superconducting suspension of the rotor-flywheel of the experimental sample of the storage complex and its control system; d) experimental comprehensive tests of experimental samples; e) adjustment of the KTD based on the results of the manufacturing technology and experimental comprehensive tests. CONCLUSION. The results obtained in the work are of great importance for the development of distributed energy in the Russian Federation. The ECD of the storage complex and the test base, as well as regulatory documents for the operation of the storage complex in various power supply systems have been developed. The NC can be used in traction electric systems of electric transport, distributed electric networks with alternative power sources. The application of the developed NC is especially effective in power supply systems operating in low temperature conditions, for example, in the Arctic and space.
