求翻译：并通过励磁变频器控制转子电流的频率、相位和幅值来间接调节定子侧的输出功率。这种结构不能分离DFIG与电网之间的联系，导致机组对电网故障非常的敏感。是什么意思？

And excitation frequency converter to control the rotor current frequency, phase and amplitude to indirectly adjust the output power of the stator side. This structure can not be separated between dfig the grid, resulting in a unit on the power grid failure is very sensitive.

Through the field and the magnetic drive control rotor current of frequency, phase and amplitude to indirectly adjust stator side of the output power. Such a structure cannot be disengaged and the grid DFIG links between units, resulting in failure of the power grid is very sensitive.

And through the excitation frequency changer control rotor current frequency, the phase and the peak-to-peak value comes the indirect control stator side the output.This kind of structure cannot separate between DFIG and the electrical network relation, causes the unit to the electrical network brea

And rotor excitation inverter current's frequency, phase and amplitude to indirectly regulate the stator output power. This structure cannot be separated DFIG and the links between the network and cause the unit to the power grid and is particularly sensitive.

through the field and the magnetic drive control rotor current of frequency, phase and amplitude to indirectly control the output power stator side. Such a structure cannot be disengaged and the grid DFIG links between units, resulting in failure of the power grid is very sensitive. ;
