|Title:||PASSIVE CONTROL METHOD, DEVICE, AND STORAGE MEDIUM FOR BIPOLAR VOLTAGE SOURCE CONVERTER|
A passive control method, device, and storage medium for a bipolar voltage source converter (VSC). The method comprises: controlling one VSC polarity on an inverter side to unlock, performing constant alternating current voltage control thereon, controlling the other VSC polarity on the inverter side to lock phase with an outputted phase of the VSC polarity, and controlling said other VSC polarity to unlock after the phase locking. In this way, the present invention enables stable unlocking of the two VSC polarities, maintains a synchronized voltage phase between the two VSC polarities after the unlocking, and provides stable power supply to a same passive network.
