Introduction For a safe reator operation in PWR,the pre-diction of the pressure during various transients isessential.For this purpose,the pressure predic-tions made by the computer codes based on theequilibrium pressurizer models developed in theearly 1 96 0 ' s are not always satisfactory. TheThree Mile Island(TMI) accident has resulted inan increased emphasis on the capability of simulat-ing system transients with greater accuracy[1] . Fora pressurized waterreactor,the accurate pred… 相似文献

A pressurizer is one of important equipment in a pressurized water reactor plant. It is used to maintain the pressure of primary eoolant within allowed range because the sharp change of eoolant pressure affeets the security of reaetor,therefor, the study of pressurizer‘s pressure eontrol methods is very important. In this paper, an adaptive fuzzy eontroller is presented for pressure control of a pressurizer in a nuclear power plant. The controller can on-line tune fuzzy eontrol rules and parameters by self-learning in the actual control proeess, whieh possesses the way of thinking like human to make a deeision. The simulation results for a pressurized water reactor plant show that the adaptive fuzzy eontroller has optimum and intelligent eharacteristies, whieh prove the eontroller is effective. 相似文献
