Operator Support System
Original language description
The establishment of NPP Dukovany units in frequency and power control leads to new requirements on increase of the plant diagnosis level, i.e. introduction of new functions and outputs which the present system does not fulfil. Further there are new demands on higher quality and correctness of information system outputs for the operator support. It means that the plant is operated not only in the base load operational mode but in the load follow mode as well. The stability of the main unit parameters, unit power output and main steam header pressure, is the characteristics feature for this mode of operation of units with VVER 440 type of reactors. This does no more hold in the new mode in which these both principal parameters vary in dependency on thepower network frequency changes. This fact, however, has an important impact on the activities of the control room operators. Therefore, in order to help them to adapt themselves easily and without unnecessary stresses to new conditions.
