摘要
Abstract
Against the characteristics of a Siemens 660 MW unit's shaft sealing system which is not equipped with spray attemperator and redundant steam supply,a novel control strategy was put forward.On the basis of coupling pressure regulation with steam supply valve and overflow valve as actuators,the control strategy adopted steam desuperheating instead of spray desuperheating, which achieved automatic control of shaft sealing steam parameters under each working condi-tion.By comparison with the original control strategy,some suggestions were proposed against the defects of existing Siemens control strategy.关键词
