The aim of the work is a computational study of the effectiveness of the extended schedules of heating regulation at steam turbine CHPPs with a decrease in the normative design temperature of the supply water. The study was carried out on adequate mathematical models of CHP turbines and heat supply systems, considering heat pipelines' actual diameters and lengths. The main energy effi-ciency indicator is the specific reference fuel consumption for electricity supply, calculated under comparable conditions for the operating modes of turbine plants and the load of the heat supply sys-tem. The study took into account the electricity consumption for the drive of network pumps, standard heat losses in heating networks and the electricity generation for the heat consumption of CHPPs. The study results allowed for the first time to determine the integral indicators of the energy efficiency of work during the transition of CHPPs from the normative design ones to the temperature schedules re-duced by the temperature of the supply water. At the same time, the calculations revealed the limita-tions on the parameters of the extended schedules of regulation when transitioning to reduced tempera-ture schedules. The most important results of the work should also be attributed to the determination of the optimal schedules of the temperature of the supply water for different values of the district heat-ing coefficient of the CHPP. The results obtained are essential for assessing the efficiency of the tran-sition of heat supply systems to reduced supply water's design temperatures when using modern heat-ing regulation schedules. |
