“…During the development of the concept of creating a combined energy source, a scheme for the combined power supply of an autonomous consumer based on micro HPP [1] with a builtin axial-type turbine in the siphon penstock was proposed (figure 2). This scheme solution allows to provide follow: • stable and reliable operation within the daily cycle; • increased manoeuvrability with discrete power control; • the use of several hydraulic units of various power capacities for emergency backup; • the principle of modularity (increasing installed power capacity depending on the needs of the consumer).…”

The report examined new scientific approaches to the creation of a combined cogeneration energy complex based on small or micro-hydropower. The most effective approaches to micro-hydropower facilities were considered to create a workable structural layout. A criterion has been developed that allows to evaluate the energy efficiency of hydroturbines at an early stage of design using the calculation method, including a predictive estimate of the hydraulic resistance function ξHT = f(Re) of a particular penstock geometry. The results of the theoretical task of creating a technologically advanced configuration of a blade system using Zhukovsky theory. By calculating and numerically (CFD) simulating the hydrodynamic lattices of flat profiles, the theoretical nomograms for determining the coefficients Cx and Cy are confirmed and supplemented. A series of comparative results of computational and experimental studies of the combined energy complex hydraulic part – microhydroturbines with experimental blade systems, including those modified by the principle of biomimetics (nature imitation technologies) is presented. Based on the calculated and experimental studies, the prospects of the chosen direction of development of small and microhydroenergy are shown, as well as the effectiveness of the approaches that were used in the design of the working bodies of microhydroturbines.

Within the context of energy efficiency and environmental safety, the creation of energy and water supply systems integrated with the units for utilization of combustible waste, low-pressure gases and industrial wastewater are of high priority for oil and gas enterprises. A method for the synthesis of these rational systems and a two-dimensional model for evaluating performance indicators are proposed. We have developed alternative structures based on the block-modular principle of equipment composition formation, which allows structurally parametric integration of energy and utilization modules with technological productions; performed pre-project evaluation of the effectiveness of alternative options for the energy and water supply system with the utilization of low-pressure gases, thermal neutralization of industrial wastewater for methanol recovery plants and designed a multipurpose oil and gas condensate processing enterprise. Integration of utilization, energy and technological installations in energyand water supply systems allows reducing the consumption of heat and electric energy from external sources by 56–100%, and water consumption by 40–50%. Accordingly, the cost of wastewater reducing by an average of 76–93% for oil and gas condensate processing facilities. Almost complete utilization of low-pressure hydrocarbon gases is achieved (the volume of flared emissions is reduced by 90–98%).
