摘要
简述了牵引变电所常用的两相-三相逆Scott变压器与纯单相所用变压器的谐波传递特性,通过对比分析常用的单调谐滤波器与二阶高通滤波器的原理特性,制定了采用二阶高通滤波器应用于所用变低压侧的谐波治理方案,并研制出谐波抑制装置,通过现场实测数据分析验证了该谐波治理方案的有效性。
The paper illustrates the characteristics of harmonic transmission of two phase-three phase inverse Scott transformer and pure single phase auxiliary transformer employed in traction substation,establishes the scheme for treatment of harmonics at low voltage side of auxiliary transformer by application of second-order high-pass filter on the basis of comparison and analysis of principles and characteristics of commonly used single tuned filter and second-order high-pass filter,by which the devices for suppression of harmonics are developed,and the effectiveness of the scheme for treating of harmonics is verified after analyzing of tested data at site.
