Abstract: The present invention provides an electric tool comprising a body, an operating component, an output shaft, and a stop mechanism. An arresting disc is disposed on the output shaft, and a groove is formed on the arresting disc; the stop mechanism comprises a protrusion, for example, a pin, which is operable so that the protrusion extends to insert into the groove to lock the output shaft. A stop mechanism of the present invention is easy to operate, delivers good safety performance, and has a relatively simple structure, which allows convenient production and subsequent maintenance. Further, a stop mechanism of the present invention automatically springs back to a non-stop position at which it detaches from the output shaft or the transmission gear of the transmission mechanism when the external force is lost, which prevents possible damage to the output shaft or transmission mechanism when a user starts the electric tool before releasing the stop mechanism.

Abstract: Provided is a method for analyzing the stability of a PMSG-WT connected to a weak power grid considering the influence of power control. New energy power generation mostly uses a perturbation and observation (P&O) method for maximum power point tracking, and nonlinear discontinuous links therein make stability analysis difficult. The present application analyzes the stability of the PMSG-WT connected to the weak grid system based on a describing function method, and fully considers the nonlinear discontinuous links in the power loop, thus making the analysis result more accurate. At the same time, the describing function method is a method that can quantitatively calculate the frequency and amplitude of oscillation. The analysis method of the present application can provide a powerful and good reference for oscillation suppression and controller design.
