My attempt

Attempt (for circuit 1)

The results I got are close to the required answer, but there is a question asking for drawing the open circuit and short circuit tests characteristics .. I tried to solve it, but Isc and Vt (in open circuit) are decreasing with the increase of the field current , so I didn't get the right answer. Could someone let me know where is my mistake ? Machine parameters

Three-phase programmable voltage source parameters Three-phase programmable voltage source load flow

  • \$\begingroup\$ You haven't said what Vt measures or where Isc is measured. Don't you think it would be important to state these things? \$\endgroup\$ – Andy aka May 9 at 8:01
  • \$\begingroup\$ Vt ( circuit (2)) measures the open circuit voltage, and Isc is measured in circuit (1) \$\endgroup\$ – user555412 May 10 at 1:24
