Back-to-back converters are the main components of a doubly-fed induction generator (DFIG). If the loadings of the rotor-side converter (RSC) and the grid-side converter (GSC) are balanced

the capacity and the cost of the DFIG will be reduced. This paper balances the converters' loadings by adjusting reactive power of the GSC <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(Q_{\mathrm{g}*})$. The steady-state constraints of the DFIG are solved to quantify the imbalance degree. A sensitivity model of the unbalanced loading with respect to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{\mathrm{g}*}$ is proposed to balance the loadings. To verify if loading adjustment reduces the stability of the DFIG

the eigen-sensitivity models

with respect to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{\mathrm{g}*}$ and stator voltage

are newly proposed with the power flow Jacobian matrix. Numerical results verify the accuracy and efficiency of the proposed model. The loadings of the converters are balanced with a few adjustments. Loading balance has little negative impact on the stability of the DFIG.
