1. Why Do SVGs Generate Harmonics? Unlike ideal components, the real-world power electronic switches (IGBTs) in an SVG do not switch sinusoidally. They use Pulse Width Modulation (PWM) to synthesize a sinusoidal output current. This switching action is the primary source of harmonics. PWM Switching Frequency Harmonics: The output voltage of the SVG's H-Bridge inverters is a series of high-fre...
IN any system containing nonlinear loads that use phase-angle control or abrupt switching, particularly those that draw a non-sinusoidal current. The specific range of "2nd to 51st" is a classic signature of certain technologies.Here are the most common places where you would find such a wide harmonic spectrum: 1. The Classic Example: Thyristor-Controlled Reactor (TCR) in SVC Plants This is the mo...
Have you ever been troubled by these frustrating issues? Production lines in your factory halting without warning, causing massive financial losses? Lights in your office building flickering inexplicably, servers restarting frequently, putting data at risk? Receiving shockingly high electricity bills every month, with unexplained "penalty" charges? Electrical equipment overheating, lifespan shorte...
Unlocking 35% Annual Energy Savings: How Smart Monitoring Transforms Your Bottom Line For commercial and industrial facilities, energy costs are more than just a line item on a budget—they’re a direct driver of profitability. Yet far too many organizations leave significant savings on the table, simply because they lack visibility into how, when, and where they use power. The numbers d...
Key Benefits of ESS and EMS Integration Energy systems are changing fast. More homes and businesses now use clean power. This shift creates new needs for storage, control, and steady power flow. One clear answer is the integration of Energy Storage Systems (ESS) and Energy Management Systems (EMS). This article explains why this mix matters and how it helps users. It also incl...
Power Quality Survey: A Comprehensive Practical Guide fromPlanning to Implementation The stable operation of power systems is the core guarantee for industrial production, commercial operations, and even daily life. However, power quality issues such as voltage sags, harmonic pollution, and grounding abnormalities often lead to equipment failures, reduced production efficiency, and even safet...
Power Problems? Two Tools That Fix Them for Good Does your facility have any of these issues?---- Energy bills that are too high. Machines that run hotter than they should. Production lines that stop unexpectedly. Often, the problem isn't your equipment. The problem is the quality of the electricity that powers them. It's like giving an athlete dirty water to drink—performance w...
Power Quality Survey: A Comprehensive Practical Guide from Planning to Implementation In industrial production and commercial operations, the stable operation of power systems is the core foundation for ensuring equipment performance and improving production efficiency. However, power quality issues such as voltage sags, harmonic pollution, and grounding faults often lead to abnormal equipment shu...
