<b>Parameter Notes:</b><br /></p><p><ol><li>Parameters <b>j</b> through <b>Vslow</b> specify a general purpose stabilizer with 3 lead-lag phase advance blocks that is compatible with the WSCC stabilizer model.</li><br /></p><p><li>Parameters <b>T1</b> through <b>T4</b> specify an input frequency signal boost transient stabilizer trigger circuit that is compatible with the WSCC stabilizer input triggering logic.</li><br /></p><p><li>In normal use <b>Tdelay</b> should be set to a large value to disable the triggering of external boost action and <b>Kqv</b> should be set to zero to disable the voltage input path. That is, <b>Tdelay</b> should normally be large and <b>T1</b> and all other following parameters should normally be zero.</li><br /></p><p><li><b>Tq</b> must be greater than zero. <b>Tqs</b>, <b>Tqv</b>, <b>Tq1</b>, <b>Tq2</b>, <b>Tq3</b>, <b>Tpq1</b>, <b>Tpq2</b>, <b>Tpq3</b> may be zero.</li><br /></p><p><li>If <b>Vslow</b> is greater than zero the minimum output limit is (-<b>Vslow</b>). If <b>Vslow</b> is negative the minimum output limit is <b>Vslow</b>.</li><br /></p><p><li><b>Vcutoff</b> may be zero to disable the stabilizer cutout logic. This logic is active if <b>Vcutoff</b> is greater than zero.</li><br /></p><p><li>The voltage boost signal transient stabilizer can be specified using time constants <b>Td1</b>, <b>Td2</b>, voltage signal <b>Vk</b> and limit <b>Vtl</b>. The transient stabilizer is operated by the action of the remote relay or by closing the normally open switch <b>Sw1</b>.</li><br /></p><p></ol><br /></p>
