POWER SUPPLY SYSTEM, POWER CONVERSION APPARATUS, AND MEASUREMENT POINT SWITCHING APPARATUS

摘要

In the present invention, a self-contained distribution board is fed with power from a distribution board during a period in which power is supplied from a system power supply, and is fed with power from a self-contained terminal of a power conversion apparatus during a period in which power from the system power supply is suspended and has a specific load, etc. connected thereto. A measurement point switching apparatus selects one of a current sensor for monitoring a current passing through a master breaker and a current sensor for monitoring a current supplied from the power conversion apparatus to the self-contained distribution board. A fuel cell uses output of one of the current sensors to adjust the output thereof so that the power outputted therefrom is consumed by a general load and the specific load, etc.
