A short-time dynamic scaling approach is extended to study the depinning transition of the two-dimensional frustrated XY model driven by external currents. We investigate the scaling behaviour of depinning transition in the XY model with three different flux densities f = 1/2, 1/25, 1/30. The short-time scaling behaviour in the depinning transition of the two-dimensional XY model is clearly shown up. Besides the critical current, the exponent. is obtained.
