| Abstract: | Taking condensate system, feed water system, boiler water system, saturated steam system and superheated steam system as research objects, which were all subsystems of water-steam chemistry process in power plant, the fuzzy relation between fault signs and fault reasons was analyzed. In order to establish an applicable diagnosis model for water and steam chemistry process, uncertain reasoning method was used to construct subsystems model blocks and jumping conditions. This model can identify faults rapidly and accurately. |
