Storage Optimization (r, Q) Strategy under Condition-Based Maintenance of Key Equipment of Coal-Fired Power Units in Carbon Neutrality Era

For the safe, stable, and economic operation of thermal power units in new systems, condition-based maintenance mode storage strategy key equipment materials for generation enterprises were selected. According to linkage demand maintenance, a Weibull probability density function was used calculate spare parts demand, an intelligent optimization model with availability constraint established. The application cases cost high-value low-value coal-fired analyzed, respectively, influence different life spans number covered on expounded. results show that borne by single unit is greatly reduced via inventory (r, Q) premise not less than 99.5%.
