Abstract:
1. A handy terminal for a wind turbine generator, comprising: a connecting portion adapted to be connected to a connector provided in the wind turbine generator, an operating ends group including an operating end to generate an operating signal which selectively validates a control logic within a control circuit provided in the wind turbine generator, and a display portion for displaying an operating state of the operating ends group, wherein the operating ends group includes a mode selecting button for selectively validating one of a maintenance mode and an operating mode, a rotor turning button for switching to a blades pitch control state which defines a rotor turning state, and in the rotor turning state, blades of the wind turbine generator side are driven in a predetermined low speed which is lower than a rotational speed in the operating mode with adjusting the pitch angle of the blades according to the rotational speed.
