Abstract: A protection circuit for a wind turbine generator that includes a PWM Brake that works in conjunction with known Brake Relays is disclosed. The Brake Relay is used to short the generator output terminals at a first threshold voltage. The PWM Brake includes one or more switching devices, coupled across the generator output. The PWM Brake is under the control of a PWM Brake Control Circuit which actuates the PWM Brake at a second threshold voltage that is relatively lower than the first threshold voltage. In accordance with an important aspect of the invention, the PWM Brake Control Circuit includes a novel speed sensing circuit for providing a signal representative of the speed of the turbine generator The novel speed sensing circuit eliminates the need to mount a speed sensor on the pole top mounted turbine generator. As such, the need for adding cabling from the pole top mounted wind turbine generator is eliminated.

Abstract: A data backup method for logical volume manager (LVM) is used for backup the original data in the LV when adding newly data into a logical volume of the LVM. Before adding a snapshot volume, a new storage space is created. The LVM writes the data to be altered in the logical volume into the new storage space. The LVM then renames the logical volume to the snapshot volume, and names the new storage space to the logical volume. According to the method, reading and writing times of the physical disk can be reduced, so as to quicken backup efficiency.
