Rail Transit Power Quality Optimization Case
Project Overview
This solution focuses on power quality optimization for the rail transit industry, serving well-known cable enterprises and key projects of subways, high-speed railways and airports. The on-site loads are mainly composed of frequency converters, rectifiers and welding equipment, forming mixed two-phase and three-phase loads with fast load fluctuation and severe harmonic distortion. The industry imposes extremely high standards for power factor and power quality.
Solutions
We adopt a targeted power quality governance configuration:
1）JL-TSVCG composite dynamic compensation device and harmonic protector
2）Active power filter assembly, filtering 2nd to 50th order harmonics
Application Effects
This integrated solution efficiently filters 2nd and higher-order harmonics and provides fast linear reactive power compensation. It greatly reduces harmonic interference and suppresses system harmonic amplification, effectively improving the overall power quality and ensuring stable operation of power systems and precision equipment.
