Repowering of Lowshan Power Plant

Nowadays, repowering is considered as the most common methods for improving status of current power plants. Each methods of repowering from “para repowering” to “full repowering” shall probably be the best choice for special national and economical power plant. In this paper different repowering methods have been introduced. Moreover, application of those methods were investigated for Lowshan power plant. Technical calculation including parts designing as well as calculations concerning to heat cycle changes have been done for each methods. Additionally, by paying attention to the technical limitations an economical study have been performed for comparing the said two methods.
