Abstract

In view of the current situation of frequent wide load regulation and long-term ultra-low load operation of coal motor units under the new power system, this paper established the calculation model of the added value of energy consumption cost of steam turbine generator units, and put forward the method of taking the added value of energy consumption cost, maintenance cost and power supply benefit loss as the maintenance cost, and taking the maintenance interval corresponding to the lowest maintenance cost per unit power generation as the economic maintenance cycle, Thus, considering the difference of performance degradation law of different units, the maintenance cycle was determined pertinently. The method was applied to a 600 MW unit, and the influence of different maintenance cycles on operation cost was analyzed.
