Industry Overview
With the rapid growth of smart cities, the demand for energy efficiency in commercial plazas, residential areas, and public facilities is rising. Power equipment is widely used to improve energy efficiency, safety, and reliability.
Sources of Harmonics
Harmonic pollution mainly comes from devices like variable frequency drives and rectifiers, used in lighting, UPS systems, and office equipment. These generate 3rd, 5th, and 7th order harmonics, with distortion rates typically reaching 10-30%.
Key Issues
High-order harmonics are found in the zero line of three-phase systems, leading to overloads, overheating, insulation damage, and even fire hazards.
Solutions
Ikonmac’s AHF filters harmonics (2nd-50th order), especially targeting the 3rd, 5th, and 7th orders. It balances three-phase systems, reduces neutral line current, and improves power factor, ensuring safer and more efficient operations.
Successful Cases
Nanjing Olympic Sports CenterReactive Power Compensation Project
Project Overview
The Nanjing Olympic Sports Center is located in Nanjing, Jiangsu Province. It is a world-class sports venue and represents top-level facilities in Asia, providing multi-functional areas including a stadium, swimming pool, and sports technology centers.
Analysis and Solution
The center’s main energy load comes from LED lighting, large HVAC systems, and other high-consumption equipment. Harmonic issues arise from the operation of these systems, requiring comprehensive solutions. The project utilizes iKonMac’s SVG, rated at 600kvar, to ensure stable and reliable operation.
Module Performance
The analysis shows a significant improvement, with harmonic distortion reduced from 26.8% to 4.1%. The system’s efficiency is notably improved, ensuring the safe and stable operation of the power supply.
