    • A communication apparatus includes a display device, a camera, a database, and a server. Display information is displayed on the display device. A viewer image of a first viewer, who is watching and listening to the display information, is taken with the camera. The display information is associated with the viewer image that has been taken with the camera. The display information and the viewer image are stored in the database that is connected over a network. The server reproduces the viewer image in association with the display information. A second viewer who has watched and listened to the viewer image of the first viewer is able to know the reaction of the first viewer, and thus new communication resulted from the reaction of the first viewer can be expected.

    • With a method whereby reactive power is changed from a fluctuating output to a constant output by a frequency rise or fall monitor circuit stage level being exceeded, and an isolated operation is detected, a problem occurs with a small scale grid in that, as the frequency is liable to fluctuate due to a load fluctuation, there is liable to be a false detection of an isolated operation. In contrast, an abnormal frequency stage detection can be performed such that the frequency at a point when the rising edge of a reactive power fluctuation is detected, and the frequency at a point when the falling edge is detected, are detected sequentially, and an abnormal frequency stage detection is recognized when the order of the difference between the current detection value and the previous detection value is “increase”, “decrease”, “increase”.

    • The disclosed distributed power supply system does not become disconnected from a grid simultaneously with others when the grid voltage falls instantaneously. In a distributed power supply device which controls an inverter circuit 10 based on a control signal obtained by comparing a predetermined carrier signal and voltage command signals of three phases and which converts DC power to AC power and supplies the AC power to a power grid of a three-phase AC power supply, fundamental wave signals of three phases are generated from a grid voltage of the three-phase AC power supply. A reference cosine wave signal is generated from the fundamental wave signals of three phases. A third harmonic signal is generated from the reference cosine wave signal and the fundamental wave signals of three phases. The three-phase fundamental wave signals and the third harmonic signal are added to generate voltage command signals of three phases.
