Problem

·Generating harmonic currents

·Low power factor

· Severe three-phase imbalance of the power supply network

Solution

In the rail transit power supply system, as an important part of the rail transit power supply system, the traction load of the electric locomotive is a high-power single-phase rectification load with large fluctuation, which has the characteristics of asymmetry, nonlinearity, large fluctuation and high power, generatinghigher harmonics and fundamental negative sequence currents will be generated. The resulting power quality problems mainly include harmonic current.Thus for the subsequent power quality problems including the harmonic current, lightning protection of the system, overvoltage and grounding, among whichthe most prominent one is the harmonic current. Therefore, for the power qualityof rail transit, the harmonic control is especially important. In order to solve the power quality problem of the rail transit industry, Creat-Poreen has installed APF, SVC, TSF, SVG and other equipment.
