Japanese Patent JP6466748
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an individual operation detection system capable of controlling the dealing for the individual operation of a plurality of inverters in a unified manner.SOLUTION: A plurality of inverters in an individual operation detection system has an inverter circuit, an individual operation detector, and a first communication unit. The inverter circuit converts a DC power, supplied from a DC power supply, into an AC power supplied to a load. The individual operation detector detects individual operation based on a change in the frequency of the AC power. The first communication unit transmits the individual operation detection results to a centralized controller. The centralized controller has a second communication unit, and a control unit. The second communication unit receives the individual operation detection results. The control unit controls the plurality of inverters so as to interrupt the inverter circuit and a system power supply, based on the individual operation detection results received from one or a plurality of inverters, out of the plurality of inverters.SELECTED DRAWING: Figure 6
