Evaluating the Safety of Thermal Power Plant via Grey Clustering
He Liu, Ya-jing Wang · 2009
A method of employing grey clustering to evaluate the safety of thermal power plant was proposed. The safety class of thermal power plant was classified for five grades. The feature space, which represented safety characteristics of thermal power plant, was put forward. The concrete evaluation contents of feature space were provided. The feature vector value to evaluate safety of thermal power plant was got by Delphi's method. Improved grey clustering based on triangle whitenization function was used to cluster feature vector. Membership degrees belonged to each classification and grey variable weight clustering coefficients were calculated and the safety level of thermal power plant was finally confirmed. The results show that the method can effectively classify the safety level of thermal power plant and provide a way of evaluating safety of thermal power plant.
