Repair of the technical condition and optimization of costs for the operation of the power plant

Abstract

The article uses the example of a 300 MW coal dust generation unit to consider possible cost minimization during operation of the generation plant after transition to the repair schedule based on technical condition. A mathematical model is developed that allows calculating the optimum interrepair resource of the generation unit in case of different types of reference fuel consumption growth during its operation. The article shows that if the reference fuel consumption grows by 3%, and if the machine has been running for 30,000 hours after overhauling, the time for the next overhaul of the equipment should be scheduled on the basis of safety and reliability parameters, irrespective of reduced efficiency of the equipment.
