A system and method for stopping a wind turbine in a battery charging circuit includes a step to terminate battery charging by opening a first switch between an electrical generator coupled to the wind turbine and the battery. A second switch between the electrical generator output terminals is then closed in order to short the generator, create a drag on the wind turbine and ultimately stop its rotation. The signal to open the first switch is generated by a battery charge monitor which when sensing a full charge on the battery will open the first switch and close the second switch. In another embodiment, there is a wind turbine auto stop signal generator connected to the battery monitor to close the second switch upon receipt of a signal indicating full battery charge from the battery monitor. In yet another embodiment there is a remotely located control computer networked to the battery monitor and the wind turbine auto stop signal generator. In still another embodiment the computer is able to receive data inputs from a variety of sources, such as weather services, to assess conditions dangerous to wind turbine operation. |
