<font color="#0f0f0f"><b>Parameter Notes:</b></font><br /></p><p><ol><li>Both generators must be present and in service.</li><br /></p><p><li>Each generator must be represented in the load flow by data stated on its own MVA base. The division of power between the two turbines is determined by the values of MWbase of the two generators, not by the values of <b>Fhp</b> and <b>Flp</b>.</li><br /></p><p><li><b>Fhp</b> and <b>Flp</b> may be used to represent the presence of dual reheat stages for a single turbine. If there is only one reheat stage, between the HP and LP turbines, <b>Fhp</b> and <b>Flp</b> should normally be unity and zero, respectively, and <b>T5lp</b> should be set to the reheater time constant.</li><br /></p><p><li><b>Dhp</b> and <b>Dlp</b> give a rough approximation of the damping of intermachine speed oscillations by electromagnetic effects. When the generators are represented by the gentpf or genrou models with proper values for subtransient time constants this damping is represented accurately in the generator electrical torques and <b>Dhp</b>, <b>Dlp</b> should be set to zero.</li><br /></p><p><li><b>Rhp</b> and <b>Rlp</b> must be greater than zero. If any of the time constants are zero, they are bypassed.</li><br /></p><p></ol><br /></p>
