摘要
Device, system and one kind prevent power generation wind turbine generator (22) to be disclosed under low voltage condition to power grid (27) from tripping due to detecting. Disclosed equipment includes duration of a kind of holding collector bus voltage (26) higher than threshold voltage levels that resistor group (35c) absorbs a kind of complex power real part control system, to power grid under low voltage condition. Collector bus voltage (26) maintains the switching device being opened and closed using gating signal that those include phase delay angle.
