Huakang Co., LtdActive Harmonic Filter for Pharmaceutical Industry
Huakang Co., LtdActive Harmonic Filter for Pharmaceutical Industry
Project Introduction
Zhejiang Huakang Pharmaceutical Co., Ltd. is a high-tech enterprise under China’s Torch Program, specializing in deep processing of corncobs and starch. It develops, produces, and sells functional sugar alcohols and monitored food ingredients. Ranked among China’s top food ingredient and starch sugar enterprises, Huakang is a key drafter of national standards for xylitol, maltitol, sorbitol, and more. With internationally advanced quality, its products are sold across China and global markets.
Analysis and Solution
Huakang Pharmaceutical Co., Ltd.’s main loads include lighting, air conditioning, fans, motors, and variable frequency drives (VFDs). VFDs are the primary harmonic sources in the power distribution system, generating significant harmonics that degrade power quality and affect the stable operation of distribution and production equipment. This project implemented IKM-Active Harmonic Filter with a 400A capacity.
Performance
THDi Before Mitigation 7.5%
THDi After Mitigation 1.3%
After the equipment was put into operation, the harmonic current distortion rate decreased from 7.5% to 1.3%, demonstrating excellent harmonic mitigation performance. It effectively reduced harmonics in the power distribution system, improved power quality, lowered line losses, and ensured the stable operation of both the distribution and production equipment.
