ENERGY RESISTANCE OF MEDICAL FACILITIES DURING TRANSIENT OPERATION MODES OF THE ENERGY SYSTEM

Abstract

The question of increasing the reliability of the operation of objects in the energy system of Ukraine is under consideration. It is shown that the issue of energy supply of public facilities received new requirements during the war. Especially such requirements now apply to medical facilities. The main types of energy for medical institutions are the supply of electrical and thermal energy. For Ukraine, on the basis of climatic features, the consumption of thermal energy is much larger than that of other types of energy. Therefore, one of the important steps to reduce energy consumption is thermal modernization of buildings. This paper considers the general energy supply system, which includes not only heat supply but also electricity supply. It is necessary not only to have the electricity itself in the network, but also to meet the quality requirements. Medical electrotechnical complexes are one of the most critical to the quality of electrical energy. Correct diagnosis and maintenance of vital activity of the patient's organism depend on their work. It is proposed to assess the state of energy supply through the model of mutual dependence of energies. Therefore, qualitative changes in thermal energy indicators cannot be compensated for by network solutions. Maintaining the temperature in the premises is possible precisely due to the use of other heat sources. In terms of the energy connectivity model, the only way to equalize the "body of energy consumption" is the mutual replacement of one energy by another. Variants of equalization of the "body of energy consumption" for medical institutions are defined. A presentation of the "body of energy consumption" is proposed, with a reflection of the qualitative limits of the shape of the "body of energy consumption" in relation to thermal energy. The concept of the limit of energy sustainability according to qualitative indicators is introduced. A number of measures to support energy sustainability have been identified. In order to achieve the longest compliance with energy supply quality indicators, it is proposed to disconnect part of the premises from the energy supply system while preserving the energy supply group for those premises that will remain. It is noted that using the criterion of energy sustainability, it is possible to analyze construction structures and technological processes in the buildings themselves in order to develop measures to increase energy sustainability with a given direction.
