- W3138659462 abstract "Abstract Currently, Russian heat supply system is at the stage of not just organizational, but also technological changes. Any decisions are based on determining priority criteria. The goal of our research is to develop a set of organizational and technical solutions improving the efficiency of production and supply of heat to end consumers, taking into account the criterion that will be defined as the main one for a particular system. Current feasibility of the “generation” subsystem depends on the condition of its main generating equipment, the degree of its load, as well as the efficiency of the distribution of heat load between sources; “transportation” depends on the state of heat supply grids and the extent of their load; “consumption” depends on the state of thermal protection of buildings, losses of consumers, as well as the degree of automation of district heating substations. The criteria may be: 1. Minimum time for the renewal of fixed assets: important in the conditions of disruption of the quality of heat supply. However, research did not confirm any significant violations[1] 2. Minimum variable costs: impact on the formation of tariffs for the population and the price for the industrial consumer; 3. Minimum grid transmission losses: for most systems, they are determined by regulations, not by actual measurements on heat supply grid sites. Not only the radius of effective heat supply and revised production technologies are important, but also the location of facilities and their capacity. However, confirmation of this version calls for implementation of a system for monitoring the state of heat supply grids, for example, based on optical fiber. This can lead to the development of distributed heat energy industry at the level of house heating substations; 4. Economic and budgetary efficiency, taking into account different project financing solutions." @default.
