Steam-driven power generators rotate at a constant speed via a governor that maintains constant steam pressure in the turbine. In addition, automatic generation control (AGC) or load frequency control (LFC) is added to ensure reliability and consistency despite load variations or other disturbances that can affect the distribution line frequency output. A specific turbine- governor system can be described only using the block diagram below, in which G (s)- Gg (s)G(s)Gm(s), where is the governor's transfer function 0.2s+1 G.(s)s the...
