Method of measuring unsaturated inductances of an equivalent circuit of a synchronous machine |
摘要 |
Unsaturated inductances of an equivalent circuit of a synchronous machine are measured from the following steps: An armature resistance of a synchronous machine is measured. A time constant of an armature with damper under a quadrature-axis magnetomotive force is measured when an armature and a field are in a positional relationship wherein a magnetomotive force by flowing current to an armature coil of the synchronous machine becomes the quadrature-axis magnetomotive force. Also, a current and a voltage of the armature are measured when the armature and the field are in the positional relationship by a quadrature-axis Dalton-Cameron method. The measured values are then used for solving equations defining inductances of a quadrature-axis equivalent circuit of the synchronous machine.
