The study about the precision of standard parameter models of synchronous machine

Abstract

Based on two different hypotheses, three different standard parameter models of synchronous machine in PSD-BPA and PSASP derived from fundamental PARK equations are studied. The difference of two different hypotheses is how to consider the leakage flux linkage of the damp winding and mutual leakage flux linkage between damp winding and field winding. Assumed condition of Model A considers that there are no leakage fluxes which only linkage damp winding. Assumed condition of Model B considers the flux which linkage field winding and damping winding also linkage stator winding. Q-axis is the same. The simulations of two different parameter models of synchronous machine and Time-Stepping Finite Element Method (T-S FEM) are compared by a typical single generator-transformer-double line-infinite system. The precision of three different parameter models of synchronous machine is analyzed, Model B-1 is not recommended to adopt on power system simulation.
