Mathematical Model of governing system's dynamic characteristic for condensing turbine, reheat turbine, extractionturbine and power frequency turbine are introduced in this paper.
It is ripe in technology and doable in practice that one old condensing turbine with proper parameter is remade to be postposition turbine of the back extraction pressure turbine.
