The invention discloses a comprehensive setting method for a hybrid steam distribution function of a turboset. The method follows a steam distribution principle of set valve sequence value mapping. On-site setting of the mixed type steam distribution function is completed through comprehensive application and implementation of multiple methods such as a reverse synonym method, a sequential steam distribution method, a reverse mapping method, a valve position synonym method and a local setting method according to the sequential order of a pre-setting sequence valve and a subsequent setting single valve and according to the structural characteristics of a hybrid steam distribution configuration, and the setting quality and the setting efficiency are effectively improved. The methods are comprehensively applied and implemented, the congenital defects of a mixed type steam distribution configuration structure are eliminated; The non-linear correction of the flow characteristics of the single valve and the sequence valve are considered, the problems that the setting work difficulty is high, the efficiency is low, and many accurate interference links exist are solved, and positive significance is achieved for improving the inlet steam flow control precision of the hybrid steam distribution unit and improving the on-site setting and implementation efficiency.
