THE RESEARCH OF EMERGENCY OPERATION OF AUTONOMOUS GENERATING UNIT

Work of autonomous generating unit in a mode of short circuit with application of the capacitor store of energy is investigated. Current expressions are resulted by various systems of excitation. Estimation of clearing efficiency of a field of the synchronous machine by investigated of transients in a mode of a magnetic field clearing has been carried out. The received oscillograms of a mode of short circuit at deenergizing thyristors the activator a counter current and counter voltage have shown, that time of achievement of a current of excitation of zero value does not exceed three periods of voltage of a food.
