The Method of Determination and Detection of Abnormal States in a GT8C Turbine

The paper describes a new method of determining abnormal states and the way they are detected on GT8C turbine. The system of dividing measured parameter into three groups has been suggested. The paper puts the emphasis on the issue of identifying relevant information contained in the data set. Properties of the GT8C hav been given. The significance of monitoring the essential operating parameters has been noted. The steps leading towards the detection of anomalies related to the measure parameter have been made. The tool in form of the method for determining abnormal states shows how to easily implement and supplement the supervision over measure parameters of the machine. The use of computer assisted methods dramatically accelerates the analysis of basic components of the measured parameters thus facilitatin the possibilities of detecting the abnormal state of the machine and making a decision on the response.
