客运专线双边供电方案研究
|
摘要
我国电气化铁路一直都采用的是单边供电方式,这主要由我国电力系统的管理模式决定的。由于全并联AT供电方式具有较好的经济技术指标,我国目前的客运专线基本上都采用了这种供电方式,为了满足高速列车平滑连续受流的要求,在变电所出口处和分区所处安装了自动过分相装置,但列车在通过时会产生过电流、过电压等现象,降低系统的可靠性,同时也会造成列车速度和牵引力损失。为了降低牵引负荷对电力系统负序的影响,客运专线也采用了换相联接的方式接入电力系统,使得分区所相邻供电臂电压同相,若实施双边供电,不但可以取消分区所自动过分相装置投入,还会提高系统的供电能力和可靠性。本文对客运专线双边供电技术进行了理论分析和研究。
本文在单边全并联AT供电的基础上,提出了实施双边供电分区所的改造方案。理论研究了双边供电方式下的牵引网电流分布、牵引网阻抗、电压损失、电能损失和双边供电系统的等值电路,并且利用客运专线实际参数,进行了单边与双边电压损失和电能损失理论比较分析。
对双边供电分流电流进行了理论推导,研究了分流电流对牵引网电压损失、电能损失和变压器容量的影响,讨论了分流电流引起的电费计量问题,最后根据单边供电和双边供电的各自特点进行了技术经济比较,得出实施双边供电需满足的条件
根据本文提出的客运专线双边供电方案,在Matlab/Simulink中建立了仿真模型,利用客运专线实际参数进行仿真分析,验证了双边供电电流分布、等值电路和分流电流理论分析的正确性,并对各种短路故障进行了仿真分析。
In China, the unilateral power supply has been used in AC electrified railway, which depends on the power system management mode. For better economic and technical indexes, all-parallel AT traction system is widely used in passenger dedicated line. In order to meet the requirements of high-speed railway, the auto-passing phase separation system is installed in substation and section post. However, when electric locomotive is passing though the device, the over-voltage and over-current frequently happen, as well as the electric railway's reliability and the speed of electric locomotive is affected. In order to reduce the influence of the negative sequence current caused by single traction load, the passenger dedicated line is accessed to power systems by phase alternating connection, which makes the adjacent feedings of section post of the same phase. And if the bilateral power supply is implemented, the reliability and power supply capability could be improved, as well as the auto-passing phase separation system can be canceled. In this paper, the bilateral power supply technology for passenger dedicated line is analyzed and researched.
On the basis of unilateral power supply system, the modification scheme of bilateral power supply's section post is presented. The current distribution, impedance, voltage drop, energy loss and the equivalent circuit of bilateral power supply are studied in theory, and the voltage drop and energy loss of bilateral power supply are compared with unilateral power supply's in theory according to passenger dedicated line parameters.
The shunt current of bilateral power supply system has been deduced, and it is researched about how the shunt current affects the voltage drop, energy loss and capacity of transformer. And the problem of electricity bill measurement is discussed, which is caused by shunt current. After the unilateral power supply system is compared with bilateral power supply system, the condition is proposed, which could meet the need of bilateral power supply system.
According to the scheme of bilateral power supply in passenger dedicated line, the simulation model is built based on Matlab/Simulink software platform, and which is simulated using passenger dedicated line parameters. It is indicated that the theory analysis of the current distribution, equivalent circuit and shunt current of the bilateral traction network is correct. At last, varieties of feeder short circuit fault are simulated and analyzed.
