摘要
YN/联结平衡牵引变压器是为减轻牵引供电系统对电力系统的不良影响,有效补偿无功功率,改善负序,降低谐波含量而开发的多功能平衡变压器。本文在阻抗匹配与系统变换的基础上,建立其等值电路模型与滤波优化模型,进行了性能分析和谐波分析,具有较大的理论意义和实际意义。
In order to relieve the harmful effect of traction power supply system in electrical power system, the YN/↓△ connective balance transformer which is multi-function balance transformer is presented , it can compensate the random fluctuating inductive reactive power, improve the negative sequence and reduce harmonics. In this paper the equivalent circuit and filter optimization model is proposed based on impedance matching and system transformation. The performance and filter effect of transformer are analyzed. These have the important theory significance and practical value.
