Automation of turbogenerator design

Abstract

The purpose of the paper is to automate the most complex and time-consuming calculations when designing turbogenerators with any number of poles and various cooling systems as well as to reduce the calculation time and improve calculation accuracy. The rapid growth of the energy sector in Russia and in the developed countries of the world is ensured by the construction of thermal and nuclear power plants equipped with modern powerful turbine generators, which are complex electric machines manufactured with the use of the latest achievements of science and technology. Therefore, scientists and specialists are developing and looking for the new methods and solutions in order to improve the characteristics and designs of turbogenerators. This paper presents the methodology, algorithms and developed programs that allow automated performance of the most complex and time-consuming calculations when designing turbogenerators with any number of poles, with indirect and direct cooling of all types of turbogenerators used in thermal and nuclear power plants. The electromagnetic calculation algorithm involves the calculation of the magnetic circuit of a turbogenerator for a pair of poles with the use of modern grades of steel for stator and rotor magnetic circuit manufacture. The calculations are performed using the Microsoft Excel program. The advantage of this methodology, algorithms and program are as follows: automation of calculations, automatic construction of graphs of idling and efficiency characteristics, convenient and intuitive interface that designers can use without any difficulty.
