“…In the literature, one can also find the application of control charts and HMMs for degradation process diagnosis [34], as well as for fault detection [35], but in these papers standard p-charts and Hotelling T 2 control charts are used. Reports of other research dealing with the detection of certain types of failures at thermoelectric power plants can be found in the literature [36][37][38]. Also, HMM-based diagnostic models founded upon the condition of the system can be found in Refs.…”

In this chapter, innovative predictive maintenance technique is described with the aim of highlighting the benefits of predictive maintenance compared to time-based maintenance. The proposed technique is applied to a specific problem that occurs when time-based maintenance is applied on grinding tables of the coal mill, in coal-grinding subsystem at the thermoelectric power plant 'TEKO', Kostolac, Serbia. Time-based maintenance provides replacement of grinding tables after certain number of working hours, but depending on the quality of the coal and grinding table itself, this replacement sometimes needs to be made before or after planned replacement. The consequences of such maintenance are great material losses incurred because of frequent shutdowns of the entire coal-grinding subsystem, as well as the possibility that the failure occurs before replacement. Innovative predictive maintenance technique described in the chapter is used for solution of this problem.

“…While some shut-downs are necessary for all power plants to undertake preventive maintenance, these are typically scheduled to minimise financial loss by preventing unscheduled downtimes during periods of high energy demand (Yang, 2004). The typical maintenance period of each power plant varies, depending on the type of power plants.…”

“…Fortunately, modern computer technology and the development of diagnosis and monitoring technology have been able to make this change possible [1]. ''Condition-based maintenance'', which combines all the advanced maintenance methods and approaches, has become more significant because more and more research have been conducted in this field [2,3].…”

Reducing the enormous maintenance cost is essential to enhance the competitiveness for power plants. An overall design scheme for condition-based maintenance of induced fans is proposed for large thermal power plants. The interface of the above framework is simple and convenient; the optimum maintenance strategy is given by condition monitoring and risk evaluating. The decisionsupported system was used in Guangdong Shajiao C Power Plant. The results show that it is a feasible maintenance optimization scheme for power plants.
