Evaluation of the effectiveness of methods to mitigate technical minimum of the power unit of thermal power plant

Abstract

In article the existing methods of decrease in a technological minimum for work of combined heat and power plant in the conditions of a power supply system are considered, assessment of their efficiency on the example of the power unit of the Yuzhnaya CHP-22 with the turbine T-250/300-240 of PJSC TGC-1 is carried out, and also the main recommendations about the range of application of these methods are made. By means of a specialized program complex the settlement analysis of the main methods of the most effective passing of minima of electricity consumption is made for combined heat and power plant, in particular transfer of the turbine to the rotor pro-rate mode.
