Many iron welding factories now use solar power to save money. However, adding photovoltaic (PV) systems can create new electrical problems. One site faced huge monthly fines because their power factor dropped. This article explains how we solved this issue using advanced technology. The Challenge of Low Power Factor The site has five main transformers. Transform...
The Principle of High-Voltage Passive Filtering In high-voltage power systems, the widespread application of non-linear loads such as electric arc furnaces, frequency converters, and rectifiers generates a large amount of harmonic currents. These harmonics not only cause power grid voltage distortion and increase line losses but also may interfere with the operation of precision equipment and dama...
The Ultimate Solution for Power Quality ---SVG & AHF Reliable power quality is key for efficient work in today's factories and businesses. Two main issues often come up: harmonic distortion and wasted reactive power. Here are two advanced technologies can solve these problems: Active Harmonic Filter (AHF) and Static Var Generator (SVG). They help reduce risks and make power systems work better...
Data Center Power Quality: Harmonic Mitigation Case Study Modern data centers rely heavily on sensitive electronic equipment. Servers, storage units, and networking gear use non-linear power supplies. These components generate significant harmonic distortion within the electrical system. High harmonic levels lead to equipment overheating and unexpected downtime. A major facility recently fa...
Applicationof High-Voltage Dynamic Reactive Power Compensation Device (SVG) in Photovoltaic Power Stations 1 Introduction Driven by the "dual carbon" goals, the new energy industry has become a core driver for China's energy structure transformation. Photovoltaic power generation has achieved large-scale development due to its clean and renewable characteristics. However, affected by change...
Active Harmonic Filter vs Passive Harmonic Filter Modern facilities depend on equipment that improves efficiency and control, but that same equipment often creates serious power quality problems. In an industrial power system, nonlinear loads such as variable frequency drive units, rectifiers, UPS systems, welders, and switched-mode power supplies can generate harmonic distortion. Once harm...
