Turbine Speed Control at Steam Turbine Power Plant using control valve of long time constant

We analyzed an existing turbine speed control logic in steam turbine power plant. If it is too late to respond a valve position demand signal, it is difficult to control turbine speed. In this paper we proposed a modified control logic and showed a good result by computer simulation.
