The use of digital technologies for calculating the TEC of thermal power plants

This article provides justification for the use of digital technologies to calculate the technical and economic indicators of thermal power plants. The object of the study is the Vladivostok CHP-2. Four types of turbines are installed at this CHPP, the boiler units operate on natural gas, which makes it difficult to effectively distribute the electrical and heat load between the turbine units. The program “Digital Economy of the Russian Federation” provides a list of the main end-to-end digital technologies that need to be implemented for economic growth. Currently developed software systems perform only one specific task. The use of such programs has a number of disadvantages. These shortcomings do not allow you to make quick and correct decisions. In view of the foregoing, it is necessary to apply digital models of TPPs. The Boiler Designer software product is used as the basis for the development of a digital model. The resulting digital model can be used to calculate the TEP, as well as to optimize the distribution of loads between power equipment, depending on the change in the state of power equipment. The article presents an analytical characteristic obtained by the method of regression analysis for the turbine PR-50/60-115/13/1.2 of station No. 5 VTETS-2 of two-stage heating of network water and its application.
