The article describes a heat and power complex utilizing internal sources of consumer heat, as well as using renewable energy sources. The power complex also includes heat accumulators, cold accumulators and a cascade heat pump plant. This heat pump plant has a high conversion factor of electrical energy due to optimization of heat flows. In this article, a method for determining the energy efficiency of the heat-energy complex under consideration is disclosed.

The paper covers the calculation of aerodynamic processes in a steam turbine using modern information technology and computational methods for improving the calculation accuracy. The practical significance of the paper is the next: the model of aerodynamic processes in the steam turbine is developed and implemented; limits and prospects of the proposed mathematical model is defined. Aerodynamic processes in the turbine are characterized by uneven steam and heat flows, which significantly affect the reliability and efficiency of the turbine. The calculation was performed taking into account the complex geometry of the turbine and can be applied to any turbine of similar design with minor changes.
