The aim of this work is to reduce losses in the auxiliary system of the North-West CHPP, as well as to optimize the process of switching the first power unit of the North-West CHPP from the Finnish power system to the Russian power system. According to the data obtained from the North-West CHPP, the CHPP scheme was modeled in the RastrWin software package. As a result, the optimization of the MV operating modes was carried out by changing the number of turns of the TSN transformer, with the help of regulation under load, and an economic assessment of the results was carried out. The next stage of the work was the development of a simplified model of the scheme for the power delivery of the North-West CHPP to the Russian and Finnish power systems in the MATLAB / Simulink program, taking into account the torsional vibrations of the shafting. To determine the plausibility of the model from the MATLAB / Simulink program, a comparison was made with the results of the NIIPT research. The resulting graphs are similar in nature to the results of calculations obtained from NIIPT, which indicates the possibility of using the model in this work for further research. |
