Dynamic performance and control strategy comparison of a solar-aided coal-fired power plant based on energy and exergy analyses

The Combined gas turbine and gas turbine (COGAG) power plant has being favored more and more by the navies of various countries because of its unique advantages such as good mobility and small weight. Therefore, the research on marine integrated propulsion systems (IPS) will have an important significance. The paper will mainly simulate the running performance of generating electricity module of COGAG power plant. The most excellent project of collectivity structure dispose can be achieved by simulating the running performance of generating electricity module of COGAG power plant. Also we can achieve collectivity performance, the most excellent matching; characteristic matching technology of working condition conversing. Especially the dynamic performance and control strategy of generating electricity module of COGAG power plant were mastered. The finally research production can supply technology foundation for designing the generating electricity module of COGAG power plant.

Exergy Analyses

Exergy analysis is an important tool to identify the improvements in various industrial processes. In this study, the existing steam power plant is examined based on energy and exergy analyses. The steam network in the power plant is comprised of two sections, one of them is used for paddy drying, while other portion is used to operate the turbine for in-house electricity production. Mass, energy, and exergy balances are applied to individual equipment of the plant. The power plant is modeled and simulated using Aspen HYSYS® V10. The calculated thermodynamic values are used for in-depth analysis of the power plant. Case-studies are included in this study to show the effect of various operational parameters on the process efficiency. The analysis shows that the boiler is the major source of exergy destruction, because of the incomplete combustion process, and inappropriate insulations. The remedial actions are also suggested in the study.
