Title:
電力制御装置、電力制御装置の制御方法、分散電源システム及び分散電源システムの制御方法
Document Type and Number:
Japanese Patent JP6586517
Kind Code:
B2
Abstract:
Inrush current to a load at the time of a power outage is reduced. A power control apparatus (101) includes an inverter (25) and a controller (30). When the controller (30) detects a power outage in a power grid (300), the controller (30) performs control so that output voltage supplied from the inverter (25) to a switching device (102) rises to an operating voltage. The operating voltage is the voltage at which the switching device (102) operates to switch from electric power supplied to load devices (200 to 203) from the power grid (300) to electric power from the inverter (25). The controller (30) also performs control to maintain the output voltage at or below the operating voltage when the output voltage reaches the operating voltage and then performs control so that the output voltage rises to a predetermined voltage exceeding the operating voltage.
