A Model of Condition Evaluation of Steam Turbine Proper Based on Multi-level Fuzzy Comprehensive Evaluation
LU Gai-lin · Journal of Electric Power · 2011
Aiming at large-size steam turbine proper is difficult to evaluate its condition because of its structure is complex and its monitoring parameters are complicated and various,a model of multi-level fuzzy comprehensive evaluation is firstly proposed.The model is based on hierarchical division.By fully using operating parameters,on-line condition monitoring parameters and spot inspection data,t he condition evaluation of steam turbine proper from subsystem to system is implemented successfully.It is shown by the instance that this model is feasible an effective,the evaluated results can be used as a support in making maintenance decisions.
