Zhejiang Hongyan Electric Co., Ltd. 
SOLUTION OVERVIEW
Engineering scope and operating conditions
Coordinating nonlinear loads across modern production lines
Automated manufacturing plants frequently combine VFDs, servo systems, welding equipment, rectifiers, compressors and sensitive control devices. Their operating schedules change throughout the day, so harmonic current, reactive demand and voltage disturbance must be evaluated at the common bus rather than one machine at a time.
Recommended system configuration
- Active harmonic filters for changing low-voltage nonlinear loads.
- SVG systems for fast reactive power correction and phase imbalance management.
- Detuned capacitor banks where stable compensation remains appropriate.
- Monitoring, communication and staged expansion provisions for future production lines.
Engineering data required
Provide the single-line diagram, transformer ratings, load list, VFD and welding capacities, measured THDi and THDv, operating schedule, target power factor and planned expansion. CHYN selects equipment capacity and connection points from the combined network data.
