THE PURPOSE: The article presents the results of the development of a methodology for the design calculation of reliability and changes in the level of reliability of energy systems, taking into account the influence of control actions based on statistical methods of collection, analysis and models of experimental data processing.METHODS: The system analysis and generalization of experimental data on technological failures of the main equipment of thermal power plants were used in the calculation assessment.RESULTS: The objective function of controlling the reliability parameters of the thermal power plant power equipment is proposed. The approbation of the presented objective control function was performed, which showed the adequacy of the results obtained to assess the reliability of the main nodes and elements of the TPP power equipment.CONCLUSION: The results of the conducted studies show that when determining reliability indicators, it is necessary to take into account the actual technical condition of individual elements and resource-determining functional units of thermal power plant power equipment. The results obtained can be used to develop a methodology for evaluating control actions for calculating the output control parameters and a mathematical model for changing the output characteristics of TPP steam turbines in terms of heat and electric energy generation, as well as at the stage of developing design documentation for the creation of structural elements and practical recommendations in order to extend the service life of power equipment generating systems based on digital technologies.

Auxiliary Power

The cold-end system of steam turbine is an important auxiliary system in thermal power plant, its operating mode has a direct impact on the output of the unit and auxiliary power. This paper uses an optimization analysis method to calculate the cold-end system of a 1000MW ultra-supercritical(USC) unit, and establishes a cold-end optimization system by using VB6.0 for a domestic ultra-supercritical unit, which provides an online guide for the operator by calculating the condenser. The results show that this system can provide some guidance for unit operation.

Huge Impact

The condenser plant has a huge impact on the economy of a steam turbine power plant. Deterioration of the parameters during operation could lead to a significant decrease in electrical output and to an increase in the heat rate of the thermal power plant. Detailed calculations of the performance under different operating conditions were carried out for the condenser of the Morava thermal power plant. Comprehensive testing of the condenser was carried out and experimental data were compared with the numerical results. The effects of deviations in the condenser behaviour on the main thermodynamic parameters and the overall economics of the power plant were evaluated. Guidelines for operation of condensation plants are given in the conclusion.
