摘要
我国既有线多存在电能质量问题,新建宜万线因为外部电源薄弱,无负荷和轻负荷的概率较大等原因,导致功率因数低,电能质量差的问题较突出。目前,我国电气化铁道变电所无功补偿与谐波综合治理有多种方案,本文结合宜万线负荷特点,通过对多方案进行比选,得出了适合宜万线的牵引供电补偿方案。
There are much power quality problems in existing railways of our country, since there are some weak points in external power supply for new constructed Yi-Wan railway with great tendency in occurrence of reactive load and under-load that leads to the lower power factor and prominent degraded power quality. Currently there are many plans for compensation of reactive power and settling the harmonics in substation of our country’s electrified railways; with reference of load performance in Yi-Wan railway and after the comparison of various plans, the paper obtains the traction power supply compensation plan suitable to Yi-Wan railway.
