In Tongxiang, Zhejiang Province, a leading lithium battery material manufacturer faced critical power quality challenges caused by complex industrial loads. The facility’s main equipment — including frequency converters and heating systems — generated excessive harmonic distortion and suffered from a low power factor, leading to reduced energy efficiency and instability in production.
To resolve these issues, Enjoypowers implemented a large-scale power quality upgrade featuring 80 × SVG-100k Static Var Generators (total 8000 kVar) and 40 × APF-150A Active Power Filters (total 6000 A).
Challenges
-
High harmonic currents from frequency converters
-
Low power factor affecting equipment efficiency
-
Voltage fluctuation and grid instability
Solution
Enjoypowers’ integrated AHF + SVG system dynamically compensates reactive power and filters out harmonics in real time. This solution enhances the factory’s overall power factor, reduces THD (Total Harmonic Distortion), and improves voltage stability across the distribution network.
Results
-
Harmonic distortion reduced below national standards
-
Power factor improved to above 0.98
-
Enhanced energy efficiency and equipment reliability
-
Stable and cleaner power supply for continuous production
This project showcases Enjoypowers’ expertise in providing smart power quality solutions for the new energy materials industry, supporting sustainable manufacturing and stable energy utilization in China’s rapidly growing lithium battery sector.
