The article describes the calculation results of the technical and economical parameters dependence on heating changes in the regulation range from 0 to 55 MW and electric load in the adjustment range from 200 MW to 300 MW of a 300 MW power unit with the steam turbine K-300-240-2 KhTGZ. The article presents changes in performance indicators: power unit net efficiency, specific fuel consumption, absolute efficiency of the power unit. The power unit’s heat-and-mass balance calculation was carried out according to a standard method for thermal power plants schemes. The mathematical model of power unit operation in variable modes was developed bases on the above method. According to the evaluation results the graphs indicating: changes of power unit efficiency on the turbine unit thermal load, variation of electric load and dependence of variance in specific fuel consumption on power and heating load were produced. The dependency graphs showing change in the specific heat consumption of turbine and power unit that entirely shows the change in the power unit efficiency under thermal and electrical loads regulation were built. |
