Input data to match model and prototype states of WWER NPP

The paper considers some possible input data of NPP power unit model for solving the problem state matching with prototype state. In course work on prototype, a numerical experiment using full-scale modeling complex PROSTOR was conducted. Its essence to obtain steady states capacity from 94% 104% step 0,05%. For we used Kalinin 3 loading 4 248 effective days. When analyzing results experiment, two effects were found. One them, expressed in bend derivative obtained graph, is connected reaching upper limit possibility regulate pressure main steam collector. regulating valves turbine generator are executing mechanism regulator At break graph they open at 100%, which causes further inability pressure. collector starts increase. This effect corresponds real processes occurring NPP. this case, as one tuning parameters, it proposed use adaptive coefficient concentration boric acid reactor, control which, mathematical regulator. It also shown that impossible accurately reactor due peculiarities operation volume compensator electric heaters automatics. regard, an additional match prototype. These regulators have been successfully tested part software package and
