Load Frequency Control of Single Area System: - EEEGUIDE
A complete block diagram representation of an isolated power system comprising turbine, generator, governor and load is easily obtained by combining the block diagrams of individual components, i.e. by combining Figs. 8.3, 8.4 and 8.5.
Mathematical modelling of an isolated system(c ontd..) The block diagram representation of the generator-load model is From the above block diagram we have.....[2] where TP = = power system time constant . kp =1/D= power system gain.

MODELING OF TURBINE, SPEED GOVERNOR, AND EXCITATION SYSTEM: First order turbine model, Block diagram representation of steam turbines and approximate linear models, Mathematical modeling of speed governing system, Derivation of small signal transfer function, Fundamental characteristics of an excitation system Transfer function.
Now connect the block diagrams of governor, turbine, generator and load models to obtain the block diagram of the complete ALFC, shown in fig.(9). The primary ALFC loop has one output ∆ω and two important incremental inputs: ∆Pref = the change in speed changer setting (reference set point) and ∆P P = the change in load demand.
