Energy Efficiency Improvement of Geotechnical Systems: by Genadiy Pivnyak, Oleksandr Beshta, Mykhaylo Alekseyev

By Genadiy Pivnyak, Oleksandr Beshta, Mykhaylo Alekseyev

This publication covers cutting edge applied sciences and techniques for development of technical and financial parameters of useful geotechnical structures. the point of interest is on mathematical modelling of gadgets and methods, in addition to the improvement of innovations and their keep watch over algorithms. The publication contains schemata of useful projects fixing with regards to mine air flow and electric circuit operation, cutter-loaders and mining electric autos. It additionally demonstrates attainable functions of hybrid applied sciences and IT-methods to the paintings of geotechnical platforms. Implementation of tools and applied sciences offered within the booklet will enable to minimize power assets intake of geotechnical structures, and to reinforce environmental and fiscal parameters in their operation, being one of many crucial stipulations for sustainable improvement in smooth society.

The ebook is restricted of curiosity to technical experts, researchers, scholars and college lecturers, whose paintings is hooked up to the advance of potency of geotechnical structures.

Novoseltsev NAS of Ukraine, Institute of Engineering Thermophysics, Kyiv, Ukraine O. Kovalko Gas Ukraine State Company, Kyiv, Ukraine T. Evtukhova Institute of General Energy, Kyiv, Ukraine ABSTRACT: A comparative analysis of energy and economic efficiency and productivity of gross domestic product (GDP) in different countries is carried out.

The factors of energyeconomic interaction are defined in terms of client-alternative remuneration of ESCO services’ customer, considering payments to ESCO under performance contracts, and the client-alternative costs. The results of numerical calculations that confirm the efficiency and effectiveness of the proposed approach for improving the energy-economic security are presented. 1 INTRODUCTION maneuvering capacities, mainly hydropower, are situated mostly in Russia and Kyrgyzstan. The following parameters are of primary importance among the main factors enhancing energy-economic safety: reliability of energy supply to industry and population, timely substitution of exhaustible energy resources by alternative ones, diverse kinds of fuel and energy, prevention of their inefficient use, incorporating requirements of ecological safety and environmental protection, utilization of industrial wastes as alternative energy sources, creation of economic conditions for obtaining balanced gains from supplying energy resources and power equipment to domestic and foreign markets, rational structure of import and export etc.

The efforts should be directed onto optimization of operating modes of internal combustion engine while meeting demands for vehicle dynamics. Operation efficiency implies providing necessary torque by electric motor when ICE has unstable operation and driving the engine operating point 34 is supplied from the battery; 2) ICE delivers energy for traction and for battery charging. Capturing braking energy is a main source of fuel economy. In the braking mode, the electric motor operates as generator, delivering at least part of the energy to the battery.
