摘要

在直流偏置下，换流变压器从非饱和区工作到饱和区。绕组的谐波电流和谐波磁通增大。换流变压器将严重振动。本文利用MATLAB建立了可以在线路侧或阀侧增加直流电压的换流变压器模型。在这两种情况下，我们可以得到绕组的谐波电流值。利用ANSYS可以建立变压器的二维有限元模型。根据耦合场路理论，可以用暂态法求解换流变压器。并对比了两种工况下换流变压器的电磁特性。

Study on suppressing harmonic flux density of converter transformer core under the DC bias

Under DC bias, the Converter transformer works from non-saturated area to saturated area. The harmonic current and harmonic magnetic flux of winding will increase. The converter transformer will badly vibrate. In this paper, we build a model of converter transformer by MATLAB which can be add DC voltage on line side or valve side. Under the two conditions, we can get harmonic current value of windings. A 2D FEM model of transformer can be build by ANSYS. According to the theory of coupled field-circuit, the converter transformer can be solved by transient. And Contrasting the electromagnetic properties of converter transformer in two conditions.
