Mobile Modular Substation for Agroindustrial Complex

The strategy for the development of rural areas until 2030 is determined by the decree of the RF Government and significantly depends on the level of energy supply to agriculture. For agricultural producers, the average price of 1 kWh is higher than in the city and is about 10 cents per kWh. This increase is due to the low density of loads (an order of magnitude lower than in the city), low density of worn-out power grids, long low-voltage networks with large losses and high operating costs. In terms of energy consumption, the specifics are due to the use of outdated technologies in rural areas, the presence of additional needs other than urban ones, low electric power of rural life and a higher burden on family budgets. As a result, rural energy requires the development of special energy technologies in terms of generation, transmission, distribution and consumption. The requirements for energy supply and reequipment of agriculture are estimated taking into account the growth of energy tariffs caused by the deterioration of long worn (over 1 million km) rural networks of 6-10 kV. The solution to the problem of power supply to the village can be largely solved by the development and application of autonomous power supply systems (APPS) which can be both alternating current and direct current and a line of capacities of 0.1; 1; 10 MW, respectively, voltage of 0.4 kV, 1 kV and 6-10 kV. Taking into account the most promising solutions using RES, APPS on DC with the use of electricity storage devices are preferred. Various options for the implementation of APPS using unconventional cryogenic energy modules (CrEM), hydrogen (on fuel cells) types or bioreactors, as well as the traditional type in the form of diesel generators, gas turbine and gas piston plants are considered. A comparison of the energy efficiency of different media and shows the advantages of using hydrogen in the fuel cells, and then liquid nitrogen in the composition of the CrEM before the electrochemical accumulators in the composition of LIA. For use DC in objects of APK, it is advisable to use mobile modular substation (MMS), united KL instead of the strip VL is not only because of the greater bandwidth, reliability, but also because of the greater resistance to technogenic, natural influences, improve the environment and mobility of container substations. The article describes the structure of MMS in the form of mobile lifesupport complexes which allows to provide consumers not only with electricity, but also with heat, cold, technical and drinking water, and for year-round cultivation of fruit and vegetable crops with air flow and adjustable lighting spectrum.
