ABSTRACT:
In a power generating system the remanent voltage of an induction machine is measured. The frequency of the remanent voltage is compared to a predetermined threshold. When the frequency of the remanent voltage is greater than the predetermined threshold the induction machine is connected to the power grid. Induction machine is disconnected from power grid once generated power drops below a predetermined threshold. Once the induction machine is disconnected, it is prevented from being reconnected to the power grid until a predetermined time period elapses.
