A new technique for heat-hydraulic calculation to organize the normal operating modes of the heat supply systems intended to decide the tasks of planning and mode selecting, which ensures the required thermal loads at adherence of all restrictions on its parameters, is proposed. The main feature of the technique is in the determination of the parameters of throttling devices on the network and inlets into the buildings of consumers taking into account the differentiated corrections to the flow rates on the compensation of the heat losses in the network. The technique involves the decision of the multilevel adjustment calculation task, in which the deviations of the boundary mode parameters (pressure, flow rate, temperature) in place of the decomposition of the heat supply system model on the levels of main and distribution heating networks taking into account the intermediate control stages on the central heat points (CHP) are minimized. At each level, the task of single-level adjustment heat-hydraulic calculation is decided, which is mathematically defined as an optimization task where the internal air temperature deviation is minimized of the required value with the given accuracy a priori. The technique is realized as part of the ANGARA-TS data-computing system and allows developing the adjusting procedures to improve the heat supply quality and availability of heating consumers, determining the minimum necessary values of heads on the sources and pumping stations. © 2016, Pleiades Publishing, Inc.
