Abstract


The methods of power control unit with WWER-1000 while maneuvering on the quantitative measure of stability, namely in size of an axial offset were analyzed in this article. The settings of the power regulator were calculated. The power regulator consists of two independent parts. One of them is the axial offset regulator of the reactor and the other is the regulator of electrical power generator. In addition, the control program with a sliding pressure in the secondary loop and control program with an advanced combined-compromise method by the axial offset were compared, which is a quantitative measure of the stability of the reactor.


Keywords
