    摘要： A device for operating inverters according to the present invention can operate a plurality of inverters for converting DC output from a DC source such as a solar cell to AC output efficiently without relying on a particular inverter. The plurality of inverters are connected to the DC source through switches. DC output from a DC source is measured by a measuring device to determine the number of inverters to be operated on a basis of the output result from the measuring device. The inverters to be added or cut off are determined among the plurality of inverters at random on a basis of the random number and switches of the determined inverters are turned ON or OFF in order to select inverters to be operated.

    摘要： A grid interconnection device includes a relay controller configured to control separation or interconnection of a relay; a receiver configured to receive, from a predetermined transmission path, power failure information containing at least local area information indicating an area in which a power failure occurs; a determination unit configured to determine an occurrence of a power failure in a power distribution system, when the power failure information includes local area information of an area to which the power distribution system belongs; and a detector configured to detect an islanding state. The detector increases detection sensitivity of the islanding state when the determination unit determines the power failure in the power distribution system. The relay controller performs separation control for the relay when the islanding state is detected by the detector.

    摘要： The present invention prevents an increase in an overvoltage and increases an optimum operating voltage of a power inverter. A photovoltaic power generation device is provided with a solar cell device 1, a power inverter 2 for inverting output from the solar cell device 1 into AC power, a current path circuit 3 connected in parallel between the solar cell device 1 and the power inverter 2, and a current detection circuit 4 for detecting a current feeding back to the solar cell device 1. When a current detected by the current detection circuit 4 reaches beyond a predetermined current value, the current path circuit 3 is cut off.

The controller reads out a data communication rate at which a data communication succeeded from the data memory and directs a modem to conduct a communication at the data communication rate. A data communication is conducted at the directed data communication rate. These procedures ensure a secure link between sites and a secure data communication irrespective of a line distance between the sites etc.
