<b>Parameter Notes:</b><br /></p><p><ol><li>Per unit parameters are on base of <b>MWbase</b>, which is normally the MW capability of the turbine.</li><br /></p><p><li><b>Tr</b>, <b>Tg</b>, <b>Tw</b>, <b>Kturb</b>, and <b>Bturb</b> must be greater than zero</li><br /></p><p><li>This turbine governor model is a reasonable approximation to the performance of simple hydro plants for small motions of the gates about a given load, but it represents the variation of water inertia effect with load only if the values of the turbine parameters are properly adjusted by the user as load is varied. For idealized turbine model, set <b>Kturb</b> = 1., <b>Aturb</b> = -1., <b>Bturb</b> = 0.5.</li><br /></p><p><li>The nonlinear gain between gate position and power may be input with up to 6 points. The (0.,0.) and (1.,1.) points are assumed and need not be input. The output is not allowed to go beyond 0. and 1. However, if <b>Pmax</b> > 1., the input and output are scaled by <b>Pmax</b>. If <b>Gv1</b> is input as a negative number, the default hydro curve will be used. If input is omitted or if all zero values are input, a straight line is used.</li><br /></p><p><li>For compatibility with older versions of this model: <b>Kturb</b> = a23, <b>Aturb</b> = a11 – a13*a21/a23, <b>Bturb</b> = a11.</li><br /></p><p><li><b>Pref</b> has units of per unit speed.</li><br /></p><p></ol><br /></p>
