Mathematical model of a steam turbine back pressure  and into account the thermal load  of electric power stations

Presented is the detailed analysis of the effect the back-pressure turbine has on . the electromechanical transient processes with regard to the frequency variation in deficient areas at heat power plants and other heavy users of thermal energy. Developed are the recommendations for mathematical modeling of the back-pressure turbines for the electric power system and grids transient calcularions.
