The stator flux linkages are found and the torque is calculated Validation: This model has been widely used in the power engineering community for decades. Note that this model does not include saturation. Further, it is a reduced order model, so initial fault response will not be correctly predicted. References: [5.2.1] P. Krause, O. Wasynczuk, S.

AC WRSM Exciter Model The WRSM exciter model represents a rotating, rectifier type exciter based upon IEEEAC8B [5.3.1], and is depicted in Fig. 8.2.1. Fig. .: Synchronous Generator Exciter Model. The model structure is as follows. Inputs: The terminal voltage (V) q-axis The terminal voltage (V) d-axis Outputs: The referred exciter voltage (V) Parameters: The per-unit line-line reference voltage (pu) Automatic Voltage Regulator (AVR) proportional gain (pu) AVR integral gain (pu) AVR derivative gain (pu) AVR derivative time constant (s) AVR power stage gain (pu) AVR power stage time constant (s) AVR positive ceiling voltage (pu) AVR negative ceiling voltage (pu) Exciter field time constant (s) Exciter field proportional gain (pu)
