General model for any prime mover with a PID governor, used primarily for combustion turbine and combined cycle units.<br /></p><p>This model can be used to represent a variety of prime movers controlled by PID governors.  It is suitable, for example, for representation of <br /></p><p><ul><li>gas turbine and single shaft combined cycle turbines</li><br /></p><p></ul><ul><li>diesel engines with modern electronic or digital governors </li><br /></p><p></ul><ul><li>steam turbines where steam is supplied from a large boiler drum or a large header whose pressure is substantially constant over the period under study</li><br /></p><p><li>simple hydro turbines in dam configurations where the water column length is short and water inertia effects are minimal.</li><br /></p><p></ul><br /></p>
