Simulation of changes in the structure of technical means of automation at the VVER-1000 while maneuvering

High demands are claimed for reliability and safety of power-generating unit at nuclear power plants (NPPs). Special attention is paid to this during the so-called maneuver of capacity. For effective operation during using a power-generating unit there are three different regulation programs and combinations of them. Switching over to variable control modes is currently done by the staff, in other words by-hand. Consequetly, the issue of automation of this process is of current importance. Considering this, there was developed an optimization structure of equipment`s operation in order to ensure an efficient operation of a power-generating unit, which involves maintaining the parameters at a given level, depending on the selected control program.
