Effects of Saturation on Machine Reactances

Modeling and Analysis of Synchronous Machines

“…: (4)(5)(6)(7)(8)(9)(10)(11) L SS are stator self-inductances, L SR are stator-rotor mutual inductances, where L SR ¼ [L RS ] T , and L RR are rotor self-inductances. The inductance matrix L has the form L ½ ¼ L SS L SR L RS L RR !…”

“…VA ð Þ base : (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17) In the above equations ω B is the rated angular velocity of the rotor, k D is the damping factor (pu torque/pu angular velocity), H is the unit inertia constant (watt·s/VA at rated angular velocity), J is the axial combined (rotor and prime mover) moment of inertia (kg m 2 ), and (VA) base is the apparent power base S base .…”

“…The base apparent power is per phase [2][3][4][5][6][7][8][9][10][11][12][13][14] and the base current is…”

“…The maximum torque occurs at the angle φ max which can be obtained from [3][4][5][6][7][8] and the torque is…”

“…The theory of synchronous machines under load was developed during the first half of the twentieth century by Blondel [1], Doherty and Nickle [2,3], Park [4,5], Kilgore [6], Concordia [7], and Lyon [8] -just to name a few of the hundreds of engineers and scientists who have published in this area of expertise. In these works mostly balanced steady-state, transient, and subtransient performances of synchronous machines are analyzed.…”
