<P>PROBLEM TO BE SOLVED: To solve a problem that display content of a power generation state of a wind turbine generator on a display has to be visually observed near the display. <P>SOLUTION: An electric power detection instrument 2 is connected to the wind turbine generator 1 by an output line 61 and includes a sound wave generator 3 and an image display device 4 to monitor a power generation state of the wind turbine generator 1. The electric power detection instrument 2 changes outputs to the sound wave generator 3, the image display device 4 and a connection line 62 when the power generation state of the wind turbine generator 1 satisfies a fixed condition. The sound wave generator 3 adjusts audible sound generated according to an input signal of the electric power detection instrument 2. The image display device 4 also changes an image to be displayed according to the input signal of the electric power detection instrument 2. In the same way to a communication radio wave generator 5, the electric power detection instrument 2 changes an output to the connection line 62 to which the communication radio wave generator 5 and the electric power detection instrument 2 are connected if the power generation state of the wind turbine generator 1 satisfies the fixed condition. <P>COPYRIGHT: (C)2013,JPO&INPIT |
