<font color="#800000"><b>Parameter Notes:</b></font><br /></p><p><ol><li><b>T3</b> must be greater than zero. <b>T5</b> must be greater than zero if fast valving is used. All other time constants may be zero.</li><br /></p><p><li>The gains <b>K1</b>-<b>K3</b> and describe the division of power output among turbine stages. Normally, <b>K1</b>+<b> K2</b> + <b>K3</b> = 1.0.</li><br /></p><p><li>The times <b>Ta</b>, <b>Tb</b>, and <b>Tc</b> are all with respect to the initiation time.</li><br /></p><p><li>The value <b>Prmax</b> is a limit on the pressure in the reheater. Normally, this value should be about 1.10 p.u.</li><br /></p><p><li>A piece-wise linear characteristic for intercept valve flow vs. position is built in. This characteristic can be modified by entering up to six points in the input data following <b>Prmax</b>, in the following sequence: <b>Gv1</b> - First valve position value - p.u., <b>Pgv1</b> - First flow value - p.u., <b>Gv2</b> - Second valve position value - p.u., <b>Pgv2</b> - Second flow value - p.u., etc.  The value of <b>Pgv1</b> should be 0.0, and the value of highest <b>Pgv</b> point entered should be 1.0.</li><br /></p><p></ol><br /></p>
