Mining Heavy Industry Harmonic Governance Case
Project Overview
This solution is applicable to the mining heavy industry and serves many large mining enterprises. The on-site loads are mainly three-phase equipment such as variable-frequency motors. Although the overall power factor is high, the operation generates massive harmonics, which undermine the stability of power distribution systems and cause potential electrical safety hazards.
Solutions
We adopt a targeted power quality governance configuration:
1）Active power filter assembly: Effectively filters 2nd to 50th order harmonics.
2）TSVCG composite low-voltage dynamic compensation device and harmonic protector
3）Passive filter assembly and harmonic protector: Adopts thyristor dynamic zero-crossing switching for applicable scenarios.
Application Effects
This integrated governance solution efficiently filters 2nd and higher-order harmonics, provides fast linear reactive power compensation, reduces harmonic interference, and suppresses system harmonic amplification.
