Abstract:Grid-forming(GFM)converter is a voltage source and has good adaptability and frequency-voltagesupport in weak grid,but is prone to oscillation instability in strong grid due to impedance characteristics. To solvethis problem,based on the analysis of the impedance characteristics of the GFM converter,an adap...

Abstract:As a kind of winch driven by motor,electric winch has more excellent performance of cable control.However,in the process of retracting and releasing the cable,the drum inertia of the electric winch will change with the change of the cable stock. This unknown inertia change will lead to mismatching of motor ...
