摘要
分析了某电气化铁路供电臂末端网压偏低的主要原因,提出了在供电臂末端装设动态无功补偿装置达到末端网压提升的解决方案,并对该方案的技术原理、装置组成特点及控制策略进行了论述。装置在某重载铁路投运后,供电臂末端电压提升了2.5kV以上,同时供电系统平均功率因数达到0.98。
The main reasons of lower voltage in the terminal of electrified railway feeding section are analyzed,and the solutions of installing the reactive power compensation device in the terminal of electrified railway feeding section is proposed to improve its voltage.The theories,functional characteristics and implementation strategies of the device are also discussed.The device operation results in some heavy-haul railway show that the voltage in the terminal of feeding section was raised 2.5kV,and the power factor was kept above 0.99.
