Grid connected distributed generation (DG) can not only increase reliability, but also provide additional benefits for consumers as well as utilities. Microturbine (MT) generation system is regarded as the best way of distributed generation for its excellent performance. The paper introduces microturbine as a back-up power supply during power system black-start. It emphasizes on analyzing the characteristics of the microturbine as a back-up power supply, simulating the inrush current of the transformer and the load disturbance of asynchronous motor. The results indicate that the microturbine show excellent performance as a back-up power supply.
