Impact load treatment device for electrified railway

Abstract

The invention belongs to the technical field of flexible power transmission and transformation, and particularly relates to an impact load treatment device for an electrified railway. The device comprises a measurement module (1), a switching control module (2), an impact load treatment module (3), a standby module (4) and a harmonic elimination module (5), and is connected into a traction line in series, so that the influence of three-phase imbalance and harmonic waves is eliminated, an impact load is changed into a uniform load, the electric energy quality of the traction load and the power flow distribution of a traction system are effectively improved, the investment is reduced, and the power consumption is reduced. And electric energy loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of flexible power transmission and transformation, and in particular relates to an electrified railway impact load control device. Background technique [0002] With the rapid development of high-speed railways in my country, the power supply quality of electrical equipment also needs a higher level, which requires the power quality of the traction power supply system to go further, and complete the transformation from general railways to high-speed railways under the premise of the corresponding power quality standard transformation. The transition to electrified railways. The most important thing in the construction of high-speed railways is the safety and reliability of operation, and the most critical one is the traction power supply system, which is inseparable from the safe and high-speed operation of high-speed railways. As we all know, my country's electrified railway adopts the single-phase power fr...

Problems solved by technology

In particular, the most notable difference between high-speed rail and ordinary trains is that the vehicles are dense, resulting in frequent impact loads. In order to provide grid stability and power supply reliability, investment in the construction of traction substations and transmission lines with higher voltage levels and larger capacity; but traction The load rate of lines and substations is low, and the average power is very small, resulting in huge cost investment. Therefore, it is urgent to improve the impact of railway impact traction load, in order to achieve the sustainable development goals of reducing investment, reducing energy consumption, and reducing carbon emissions
