Abstract
The article considers additional power supply to an industrial enterprise due to the introduction of Autonomous gas-piston generator sets of modular type. In modern market conditions and the absence of a planned economy, fluctuations in supply and demand and, consequently, fluctuations in the level of instantaneous production capacity of the producer enterprise and its electricity consumption can be very significant. In addition, with the growth of tariffs for mainline electricity, one of the alternative solutions is in-house generation of electricity. For large enterprises, the power supply scheme can be divided into a basic one (supply from the main network) and an additional one (supply from a local generating source, which is initially installed as a modular one, with installed capacity regulation). This approach is universal for any enterprise, since this generating facility plays the role of an uninterruptible power supply during power outages, and during the stable power supply, it helps to save the company resources. However, the economic calculation of such an additional source of power supply, as practice shows, sometimes causes difficulties for the enterprise, and therefore it was decided to publish a practical analysis of a gas-piston generator set of a modular type. To analyze the effectiveness of implementing such installations, the equipment with common characteristics was selected. According to the analysis, cogeneration plants can operate in parallel with the main power supply source. The mobility of the modules allows you to regroup the composition of a complete transformer substation (KTP) in a short period of time, thereby changing its installed capacity. In addition, the use of a cogeneration system can be especially relevant in industrial enterprises where it is necessary to provide hot water supply and heating of industrial facilities and administrative and household premises. The calculations show that the use of gas-piston installations for electricity and heat production not only increases the reliability of the power supply system, but is also a more economical approach than purchasing energy resources from grid supply organizations at General regional tariffs. The proposed approach can be used to assess the efficiency of energy supply from power generating facilities based on renewable sources.
