摘要

文章讨论了在 VAr 静态补偿站运行的大功率变压器中，无功负荷对额外功率损耗的影响。二次侧几乎纯电容性负载和晶闸管开关的存在是相电流中高频成分的原因。变压器电感和负载电容之间的电气共振所产生的额外影响也被考虑在内。分析采用了三维有限元方法。

Additional eddy current losses in transformer working at static VAr compensation station

The article discusses the impact of reactive power load on additional power losses in a high-power transformer operating at a VAr static compensation station. The presence of an almost pure capacitive load on the secondary side together with the thyristor switches is the cause of high-frequency components in the phase currents. The additional effect of electrical resonance between the transformer inductance and the load capacitance is also taken into account. The analysis is achieved using a three-dimensional finite element approach.
