| description | Relevance. The construction sector is currently one of the largest consumers of raw materials and a major source of environmental pollution, accounting for about 40 % of energy consumption and about 30 % of greenhouse gas emissions. As a result of emissions into the atmosphere of combustion products of coal, oil and gas, irreparable damage is caused to the environment. One of the promising ways to solve this problem is the introduction of «energy efficient building» technology. The key task of designing energy-efficient buildings is the development of a power supply system, which largely determines the level of comfort and technical and economic indicators of the entire facility. The complexity of this task is caused by the fact that installations based on renewable energy sources, characterized by stochastic generation, are mainly used as power sources, and energy-efficient buildings themselves can differ significantly from each other in a number of parameters: purpose, architecture, size and number of storeys, composition of consumers etc. The article proposes an engineering technique for designing such objects and the results of its testing. The aim of study is to develop an engineering methodology for designing power supply systems for autonomous energy-efficient buildings based on renewable energy sources. Methods: methods of statistical processing of time series of data, mathematical and computer modeling using the MatLab/Simulink software environment. Results. The authors have proposed an engineering methodology for designing power supply systems for autonomous objects, focused on the design of «active» buildings with the maximum possible use of renewable energy sources. The paper describes the main design stages, which include calculation and analysis of the energy balance, choice of the main electrical equipment and development of a structural diagram of the electric power system, optimization of the composition and sizes of the main electrical equipment, selection of switching and protective devices, conductor products, development of circuit diagrams. The paper considers the practical example of application of the proposed methodology for designing the power supply system of an autonomous energy-efficient building in the Kursk region. |
