Embodiments of the present disclosure provide a video editing method, apparatus, a device and a medium. The method includes: acquiring a video editing template, wherein the video editing template is generated based on first multimedia data; displaying a video editing interface based on the video editing template, a video editing track based on a timeline is presented on the video editing interface, a first video track clip is presented on the video editing track, the first video track clip corresponds to a second video track clip formed by a first multimedia material in the first multimedia data; and in response to a material import operation for the first video track clip, replacing the first video track clip with a third video track clip to obtain second multimedia data, wherein the first multimedia material in the first multimedia data is replaced with a second multimedia material in the second multimedia data.

Video editing method and apparatus, device and medium

The disclosure provides a wind turbine generator and a control method thereof. The wind turbine generator comprises at least two power transmission systems connected each other in parallel and a control system comprising an upper controller and control subsystems corresponding to the power transmission systems and comprising bottom controllers. The bottom controllers monitor operating state parameters of functional units in corresponding power transmission systems, and when determining corresponding functional units meet abnormal conditions according to operating state parameters, send operating state parameters of corresponding functional units to the upper controller; the upper controller generates operating instructions when determining faults of the corresponding functional units occur according to operating state parameters of corresponding functional units, to control power transmission systems to work according to operation instructions. The wind turbine generator is fully used, and the energy production thereof is further increased.

Wind turbine generator including at least two power transmission systems connected in parallel with each other and control method therefor

A vibration suppression method and device of a wind power generator is provided. The method includes: calculating a specified value of a flux-weakening control parameter of the generator according to a preset value of an electromagnetic active power of the generator and a frequency of the generator; and controlling the generator according to the specified value of the flux-weakening control parameter of the generator. The method and device reduce the magnetic load of the generator by the flux-weakening control, thereby suppress vibration and noise of the generator.
