About large power turbines in thermal power plant operated with 50 Hz and 60 Hz grid frequency

Abstract

The article analyzes the characteristics of large capacity turbines in thermal power plants with grid frequencies of 50 Hz or 60 Hz. The choice of grid frequency of countries and regions in the world is largely due to historical factors. Vietnam's electricity system uses a frequency of 50 Hz, which brings advantages to thermal power plants with a simpler configuration of turbine units than plants of the same size but operating at 60Hz.
