Continuation of Prof. Władysław Latek’s research – revitalization of old power units

Open access


The research conducted by Prof. Władysław Latek (1916‒1991) has contributed greatly to development in turbogenerator design. The economical transformation taking place in Poland after 1991 initiated the process of revitalization of old power units in electric power stations. For the past 25 years, a team of scientists continuing the work on perfecting the turbogenerator design and design methods has been working in the Faculty of Electrical Engineering of Silesian University of Technology. The work of this team has led to proposing and implementing many modernization projects for turbogenerators operating in Polish power plants, as well as in power plants in European Union and Asian states. Numerous novel and innovative solutions have made it possible to significantly increase turbogenerator power, improve effectiveness of electrical energy production and reliability and safety of operation.
