Title:
METHOD FOR CONTROLLING POWER CONDITIONER AND SYSTEM INTERCONNECTION INVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/144815
Kind Code:
A1
Abstract:
A power conditioner (1) is provided with: a bidirectional power converter (2) for converting DC power supplied from an electric vehicle (3) and AC power supplied from a commercial system (5) side to each other; a system parallel-off switch (9) for electrically switching between the commercial system (5) and an interconnection point (17) to which the power converter (2), a system interconnection inverter device (7), and the commercial system (5) are each electrically connected; an interconnection relay (10) for electrically switching between the power converter (2) and the interconnection point (17); and a communication circuit (15) for enabling communication between the power conditioner (1) and the system interconnection inverter device (7). When the commercial system (5) is failed, the power conditioner (1) electrically opens the system parallel-off switch (9) and transitions to an autonomous operation after disabling the stand-alone operation protection function of the system interconnection inverter device (7).
