After analyzing and comparing two kinds of current control methods of three-phase VSR: indirect current control and direct current control, the author employs the latter as main control scheme, which is to control the phase and amplitude of ac-side current directly, by using dual closed-loop control scheme, through sampling currents of phase a and b and converting them by 3s/2r to get active component and reactive component of ac-side current.

The instantaneous power theory was employed to analyze the instantaneous power of the control winding and the control scheme for the DWIG system with diode bridge load was obtained. The component of the currents on the control-winding flux determines the instantaneous reactive power, and the component on the perpendicular direction of the flux decides the reactive power. The former one influences the DC voltage of the diode bridge on power winding and the latter one influences the DC voltage of the static excitation controller of control windings.

By projecting signals with different frequencies into the subspace I, the signal with the supply frequency has the maximum value. Consequently, in the spectrum of the reciprocal of the projecting value, the supply frequency component is cut off and the fault feature component emerges in the spectrum.

把不同频率的信号投影到子空间I，基频信号在该空间的投影将远大于其他的频率分量，因此在投影的倒数谱中，基频分量被抑制，凸显出了故障频率分量。

A new component can replace an existing component without being required to recompile the application.
