Two categories of electrical machines are available in ATPDraw: Synchronous Machines and Universal Machines. ATPDraw does not support machines in parallel or back-to –back.
|
The Synchronous Machine models in ATPDraw have the following features/limitations:
· With and without TACS control.
· Manufacturers data.
The Universal Machine models in ATPDraw have the following features/limitations:
· Manual and automatic initialization.
· SM, IM and DC type supported.
· Raw coil data (internal parameters). Manufacturers data in Windsyn.
· Saturation is supported in d, q, or both axes.
· Maximum five excitation coils, sum d and q axis.
· Network option for mechanical torque only.
· Single torque source.
The Component dialog of Universal Machines is significantly different than that of the other objects. A complete description of parameters in this dialog box is given in chapter 5.2.2 of the Advanced Manual. The WI (embedded WIndSyn by Gabor Furst) components support the following machine types; Synchronous machines with salient or round rotor with damping options. Induction machines with wound, single cage, double cage, or deep-bar rotors. The Windsyn component is documented it chapter 5.2.5 in the Advanced Manual.
The popup menu under Machines contains the following items:
