Power generation system, and method for installing the same

Abstract

In a power generation system including a DC power supply which is connected to a low-voltage distribution system to which a plurality of consumers, each having an earth leakage breaker, are connected and one wire of which is grounded, via a receiving-end earth leakage breaker, and which includes at least a transformerless inverter and an earth floating capacitance, an operational time limit of the receiving-end earth leakage breaker of the power generation system is set to a value larger than an operational time limit of the earth leakage breakers provided in the consumers. The system also includes a ground-direction determination device for determining whether a grounded position is inside or outside the power generation system. Thus, a power generation system in which an unnecessary disconnection of electric power supply does not occur when an accident of external grounding has occurred.
