<p>PURPOSE:To lower natural frequency without increasing the inertial moment of generator motor. CONSTITUTION:In a synchronous machine operating in parallel with a power system, state variables such as variation of electrical angle DELTAomega, variation of angular speed DELTAomega variation of field flux DELTAphird and variation of field voltage DELTAErd are applied, with feedback coefficients of F1, F2, F3, F4, onto an exciting system and then a control circuit regulates the natural frequency and damping ratio of the synchronous machine.</p> |
