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.

分析比较了三相电压型PWM整流器的两种电流控制方法：间接电流控制和直接电流控制。

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.

基于瞬时功率理论，推导出按控制绕组磁场定向时控制绕组的瞬时功率，在此基础上分析了带整流桥负载的定子双绕组感应电机发电系统在宽转速运行时的电压调节机理，即：控制绕组电流在控制绕组磁场及其法线上的分量，分别决定着发电系统功率绕组整流桥直流侧电压和控制绕组静止励磁控制器(static excitation controller，SEC)直流侧电压，据此提出宽转速运行时DWIG发电系统电压控制策略。
