随着近几年来铁路交通的不断发展和进步,电力机车扮演了一个极为重要的角色。电力机车主要是从电网中摘取能源获得动力的机车,其主要牵引力就来自于供电系统的接触网或第三轨。正是由于这一电力输送对电网中产生了一定的高次谐波,使得供电网的供电频率受到影响,严重影响了供电网的供电质量。文章从电力机车在电网中产生的负荷谐波进行理论分析,并使用MATLAB来对电力机车在不同的工作情况下的负荷所产生的谐波进行仿真研究,对不同工矿下的仿真研究结果进行对比分析。
With the continuous development and progress of railway traffic in recent years, electric locomotives have played an extremely important role. Electric locomotives are mainly powered locomotives that extract energy from the grid. Their main traction comes from the catenary or third rail of the power supply system. It is precisely because of this power transmission on the grid produced a certain degree of higher harmonics, making the supply network power supply frequency is affected, seriously affecting the power supply network quality. The article analyzes the load harmonics generated by the electric locomotive in the power grid and uses MATLAB to simulate the harmonics generated by the load of the electric locomotive under different working conditions and compares the simulation results under different mining conditions analysis.
