Extensible Evaluation Theory and System Development for Operating Condition of Large-sized Steam Turbine
XU Zhi-gao · Turbine Technology · 2009
On the basis of establishing indexes for condition evaluation on large-sized steam turbine,an extensible method was proposed.This method was based on matter-element theory,established an matter-element model for appraising the operating status and used a group of extensible correlation functions to calculate the correlation between the steam turbine operating state parameters and various status grades.Also,a condition evaluating system has been developed based on SIS real-time/history data platform.Finally,the method under discussion was verified by a specific case.Research results show that this method is reasonable and effective,and evaluation results may be used as a scientific basis for making decisions of condition maintenance.
