【Abstract】 The dynamic model of the main steam temperature in a 325MW peak regulating power unit has been obtained by identification and then the demands on the regulation of steam temperature control system was proposed. In order to simulation and adjusting of regulator, a transformation method converting descrete transfer function H(Z) into continuous transfer function H(s), has been developed. An effective method of tuning the parameters of double loop system based on the synthesized parameters of partially optimazation is presented in this paper Above methods are proven to be valuable in practice.更多还原
