Title:
SYSTEM LINKING APPARATUS AND METHOD FOR LINKING
Document Type and Number:
Japanese Patent JP2002112448
Kind Code:
A
Abstract:
To allow utilizing an inverter for a single-phase two-wire 200 V output widely used in a market to link a photovoltaic power generating system to a single-phase 100 V system in a solar power generation system.
The inverter 8 is not isolated between an input and an output, and converts power from a solar cell 1 into AC power of a single-phase three- wire 200 V. A transformer 10 connects lines from the single-phase three-wire 200 V with a single-phase two-wire 100 V system 4 in which one wire is grounded. A neutral point potential wire of the single-phase three-wire 200 V is connected with the grounded wire of the system 4 so that a line-to-ground fault detecting sensor 89 built in the inverter 8, can operate.
