A handy terminal for a wind turbine generator which the maintenance of the wind turbine generator, especially the maintenance work inside the nacelle, can be simplified while considering the safety of the maintenance operator. The handy terminal comprises a tower provided to stand on land or off-shore, a nacelle supported on the tower to be controlled to rotate in the yaw direction and a plurality of rotatable blades attached to the nacelle to be controlled to move their pitch, whereby the handy terminal is connectable to connecting ends respectively provided on the lower portion of the tower and the nacelle so as to perform various control of the wind turbine generator, the handy terminal further comprising: an operation button for generating operation signals for various control devices that are incorporated into a control circuit in the wind turbine generator; a display portion for displaying the operating state of the operation button; and a control portion for performing display control of the operation button, wherein the control portion of the operation button makes a mode selecting button to appear that selectively enables a maintenance mode or an operating mode of the wind turbine generator, and makes an operation button to appear that separately controls at least one of: a blade pitch control, a yaw brake control and an accessory motor provided on an oil circuit to control the blade pitch control and the yaw brake control that are incorporated in the wind turbine generator, correspondingly to a corresponding maintenance operation screen displayed on the display portion when the maintenance mode is selected from the selecting button. |
