摘要
电气化铁路牵引供电系统特殊的接线和供电方式,使电气化铁道供电系统三相无法平衡,负荷不连续及随机性大,直流驱动机车会产生大量的谐波等现象。本文对电气化铁道牵引供电系统作了全面的分析,对电气化牵引供电系统电压、功率以及谐波含量等进行了监测,根据分析及监测情况,在实际的工程中采用了MCR型动态无功补偿兼滤波装置进行了治理,经过安装前后相关数据的分析比较,说明MCR动态无功补偿装置在电压稳定、谐波治理等方面的有效性。
The special wiring and power supply mode of the traction power supply system of electrified railway makes the power supply system of electrified railway to have such phenomena as three phase imbalance,load discontinuity,large randomness and large number of harmonics generation in the DC locomotive.In this paper,the traction power supply of the electrified railway is comprehensively analyzed.The voltage,power and harmonic content of the electrified railway power supply system are monitored.The MCR dynamic reactive power compensation and filtering device is used for the control in the real project.Through the analysis and comparison of relevant data before and after installation the,the effectiveness of dynamic reactive power compensation device is illustrated in the aspects of voltage stability,harmonic control etc.
