牵引供电高次谐波对10 kV电力系统电能质量的影响及分析研究

Theory of High-Order Harmonic of Traction Power Supply for 10 kV Power System, Power Quality and Analysis of the Influence of the Research

2010年底精伊霍电气化铁路的投入运营标志着新疆铁路迈入了电气化时代,尤其是兰新客专线的快速推进预示着新疆即将揭开高铁时代新篇章。虽然新疆电气化起步晚,但在解决偏远站区信号电源单一,保证信号电源电能质量方面,乌鲁木齐供电段从新设备、新技术运用和电能动态监控等方面做了大量有益的尝试。同时,就牵引供电高次谐波对10 kV电力系统电能质量的影响及分析研究问题进行了分析和思考。

Jingyihuo Electrification Railway was put into operation at the end of 2010, marking that Xinjiang Railway entered the era of electrification;especially the rapid advance of passenger-dedicated line indicates that a new chapter in the high-speed railway will be opened in Xinjiang. Although the electrification in Xinjiang starts late, Urumqi Power Supply Company has done a lot of beneficial attempts in the new equipment, new technology, power dynamic monitoring and so on, to solve the problem of the signal power supply of single remote station, and to guarantee the power quality. At the same time, the influence of the high-order harmonic of traction power supply to the power quality of 10 kV power system, and the analysis of the research questions are analyzed and thought.
