| Abstract: | This paper introduces the corresponding thermal control DCS control strategy based on the reconstruction scheme of induced draft fan frequency converting.After the implementation,two modes of induced draft fan power frequency and frequency converting are switched under the automation mode with same output and small interference and excellent control effect is achieved to ensure the stable operation of induced draft fan and successful switching during every operation condition.The practical operation proves that this scheme has evident energy saving effect. |
