Steam pipe network balance optimization control method and system

The invention discloses a steam pipe network balance optimization control method and system.The method comprises the steps that an optimization control system is set to communicate with a converter so as to obtain production state information of the converter in real time, and the production state information comprises a first steam flow value actually generated by converter blowing; and the flow curve of the converter is corrected through the first steam flow value actually generated by converter blowing, and the second steam flow value corresponding to the corrected flow curve serves as the adjusting set value of the heat accumulator outlet adjusting valve so as to achieve steam pipe network balance optimization control. According to the method, stable operation of each steam consumption point of the pipe network can be guaranteed, the service life of all steam consumption points of the whole steam pipe network system, especially the service life of a steam turbine can be greatly prolonged, the economic ope
