The invention discloses a method and system for advanced recovery of steam condensation water. Secondary flashing of a flash tank and heat transfer of a heat exchanger are adopted, and an absorption heat pump is connected with a mixed bed and the heat exchanger. Steam is compressed to achieve temperature and pressure boosting through a steam compressor 7 and further enters a middle-low pressure pipe network so that reutilization of the steam can be realized. The advanced recovery system of the condensation water is obtained, sufficient recovery and load regulation of the condensation water areguaranteed, flashing heat of the condensation water achieves advanced recovery, heat of the condensation water is fully recovered, water resources can be cyclically utilized, utilization efficiency of the condensation water is improved and the economical efficiency is outstanding.
