The Research On Malfunction Diagnosis of Thermal Power System of Steam Turbine based on Structure Theory

摘要

The improved diagnostic technique based on the structure theory is applied to a 600MW coal fired power plant. Two typical malfunctions which only one malfunction occurs and multiple malfunctions occur simultaneously are researched by the malfunction simulation. The induced malfunctions could be separated by the sequential process model. The results show the modified diagnostic model based on thermo-economics structural theory is correct and practical.
