电力变压器的谐波电流分析与抑制措施

Harmonic Current Analysis of Power Transformers and Suppression Measures

谐波电流是影响变压器运行性能的主要因素,从对变压器谐波电流产生机理及流通路径分析的结果看,改善变压器磁路饱和状况及对变压器绕组进行合理联结可有效抑制谐波电流的产生,从而提高变压器的运行性能和改善供配电系统的供电质量.

The harmonic current of the transformer is the main factor that affects the operating performance of the transformer. The analysis result of the generation mechanism of the harmonic current and its flow path indicate that the harmoniccurrent can be suppressed efficiently through improved saturation of magnetic circuits and proper connection of transformer winding and thus the operating performance of the transformer and the power supply quality of the distribution system can be improved.
