- Abstract
In this paper, a novel inertial control method for Doubly Fed Induction Generator (DFIG) is proposed, namely mode conversion. An excellent inertial response performance is obtained by adopting the mode conversion method. DFIG operating mode can be switched between normal operating mode and inertial response mode by setting logic judgment conditions to start and block inertial control. Constant additional electromagnetic torque is set in this method, and the effect of inertial response does not recede with decrease of rotor speed. Rotor speed stability constraints for DFIG are considered in the method; the minimum rotor speed limit is determined through stability analysis of DFIG in its inertial response process. A simulation model is built to demonstrate the advantages of the proposed method. Simulation result shows that the mode conversion method can more effectively restrain the system frequency decline than existing inertial control methods within the stability operation constraints of the DFIG.
