Abstract

To improve safety during construction.SOLUTION: A second power conversion device is installed between a power storage part (SB1) and a DC cable (Cdc) connected to a DC side of an inverter. In the second power conversion device, a protection switch (SW1) is connected between a DC / DC converter (21) and the DC cable (Cdc). A voltage detection part (V3) detects voltage between a plus wiring and a minus wiring, which are connected to the DC cable (Cdc) at a detection point of a DC cable (Cdc) side from the protection switch (SW1). A control part (22) determines presence or absence of reverse connection of the DC cable (Cdc) based on voltage detected by the voltage detection part (V3).SELECTED DRAWING: Figure 2
