Power Quality Improvement Case for Hospitals, Commercial Complexes and Residential Communities

Project Overview

This solution provides power quality optimization for hospitals, commercial complexes and residential communities, serving Grade A tertiary hospitals and renowned projects of Vanke, Longfor, Yuxing Global Shopping Center and more. The sites feature mixed single-phase and three-phase nonlinear loads such as electronic rectifiers and inverters, which produce heavy harmonics and harmonic overvoltage and endanger grid operation safety.

Solutions

We adopt a targeted power quality governance configuration:

1)Filter compensation components and harmonic protectors

2)Active harmonic filter assembly and harmonic protectors

3)TSVCG composite low-voltage dynamic compensation device and harmonic protectors

Application Effects

This integrated solution filters 2nd and higher-order harmonics and realizes precise reactive power compensation. It reduces harmonic interference, suppresses harmonic amplification and optimizes grid waveforms. Eliminating current and voltage harmonics effectively, the system improves overall power quality, avoids resonance risks, and guarantees safe and stable power supply for public and residential scenarios.
