Synchronous machine whose behaviour is described by reference to a standard model expressed in one of the following forms:<br/><ul>
<li>simplified (or classical), where a group of generators or motors is not modelled in detail</li></ul>
<ul>
<li>detailed, in equivalent circuit form</li><li>detailed, in time constant reactance form</li></ul>
<font color="#0f0f0f">or by definition of a user-defined model.</font><br/><font color="#0f0f0f"><br/></font><font color="#0f0f0f"><b>Note:</b>  It is a common practice to represent small generators by a negative load rather than by a dynamic generator model when performing dynamics simulations. In this case a SynchronousMachine in the static model is not represented by anything in the dynamics model, instead it is treated as ordinary load.</font><br/><font color="#0f0f0f"><br/></font><font color="#0f0f0f"><b>Parameter Notes:</b></font><br/><ol>
<li><font color="#0f0f0f">Synchronous machine parameters such as <b>Xl, Xd</b>,<b> Xp</b> etc. are actually used as inductances (L) in the models,</font> but are commonly referred to as reactances since, at nominal frequency, the per unit values are the same. However, some references use the symbol L instead of X. </li></ol><p/>
