The objectives of an effective power plant performance monitoring program are several-fold. They include: (a) assessing the overall condition of the plant through use of parameters such as output and heat rate (b) monitoring the health of individual components such as the steam generator, turbine-generator, feedwater heaters, moisture separators/reheaters (nuclear), condenser, cooling towers, pumps, etc. (c) using the results of the program to diagnose the causes for deviations in performance (d) quantifying the performance losses (e) taking timely and cost-effective corrective actions (f) using feedback techniques and incorporating lessons learned to institute preventive actions and, (g) optimizing performance. For the plant owner, the ultimate goals are improved plant availability and reliability and reduced cost of generation. The ability to succeed depends upon a number of factors such as cost, commitment, resources, performance monitoring tools, instrumentation, training, etc. Using a case study, this paper discusses diagnostic techniques that might aid power plants in improving their performance, reliability and availability. These techniques include performance parameters, supporting/refuting matrices, logic trees and decision trees for the overall plant as well as for individual components.

Research Analysis

The increasing of electricity needs and the crisis of fossil fuels have been requiring an improvement of power plant performance, including combined cycle power plant which has important role as a provider of national electricity nowadays. Thermoeconomic analysis is one of new concept that combine exergy analysis with cost approachment to improve a system performance. In this research, analysis applied in combine cycle power plant of PT. Indonesia Power Grati. The result shows that combustion chamber is the greatest irreversibility source with an exergy destruction was found 53,81%. Where as an economic analysis obtains a different result, LP steam turbine is the component which has a huge exergoeconomic loss was found Rp 33.655.386,46/hour. Based on this result, the efforts that we can do to get an optimal performance of combine cycle power plant are preheating a combustion air to reach a perfect combustion and cleaning all the components continually.
