description: The topic of the final qualifying work is "Development of an automatic steam pressure maintenance system in the deaerator of a VVER-1200 reactor power unit with heat accumulators". This diploma thesis is devoted to the research of the mathematical model of the dynamics of the deaerator and the mathematical model of the PI controller, followed by the development of an automatic system for maintaining steam pressure in the deaerator of a VVER-1200 reactor power unit with heat accumulators. This thesis deals with the development of the system to maintain steam pressure in the deaerator with its subsequent inclusion in the general power control system of NPP power unit with VVER and thermal accumulators, in order to participate NPP power unit in regulating the frequency of network current. The paper describes a mathematical model of the deaerator dynamics and a mathematical model of the PI regulator.On the basis of these models, a computer program is developed to study the process of maintaining the steam pressure in the deaerator by changing the steam consumption to it by means of the regulator. As a result, maintaining constant temperature of feed water at the deaerator outlet, and consequently at the PG inlet, leads to unchanged parameters of the primary circuit (constant reactor heat output) with participation of the NPP power unit in regulation of the grid current frequency.
