摘要：A method for determining the optimal action zones of the centralized sources of thermal energy is developed using the calculation of the effective heat supply radius of consumers. The methodology allows to take into account the features of heat supply systems’ functioning, their technical and economic indicators, the uneven distribution of heat loads throughout the city, and limitations on the reliability of the system. Practical implementation of the proposed methodology on the scheme of operating a heat supply system is presented, the results of calculating the effective heat supply radius with their subsequent correction for reliability requirements are obtained. The application of this technique in the development of heat supply schemes for cities will allow to determine the boundaries of effective heat supply radii in all directions of the mains of heat networks, taking into account the optimal flow distribution of the coolant in them and the sections’ technical characteristics.
