CONDITION MONITORING OF TURBOGENERATORS OF A THERMAL POWER PLANT USING FUZZY LOGIC

摘要

Turbogenerator is one of the main components in thermal power plant and its maintenance plays avital role in many applications. Condition monitoring is the process of determining the condition of machinery while in operation which lessens the probability of failure by allowing the maintenance to be scheduled. In this work, vibration monitoring analysis of steam turbo generators is studied. In this study Fuzzy Logic Toolbox in MATLAB is used for analysing the health condition of the turbo generators considering displacement and velocity as parameters. For this purpose, a thermal power plant (TPP) of the Visakhapatnam Steel Plant has been chosen as a case study. This type of analysis is very useful for assessing the condition of complex systems of thermal power plants.
