Below, a self-healing capacitor supplier discusses the economic benefits of reactive power compensation:
1. Improved power quality, extended appliance life, and enhanced product quality. Power quality is measured by voltage and frequency. Voltage stability depends on the balance of reactive power. Frequency stability depends on the balance of active power. Voltage stability directly impacts appliance life and mechanical processing accuracy. Improving voltage stability by 5% could save billions of yuan annually nationwide in lighting alone. The losses from scrap, defective products, shortened equipment life, production stoppages, and power outages caused by unstable voltage and insufficient power supply are even more difficult to quantify.
2. Reduced line losses. Nationwide, line losses account for approximately 12%, primarily due to reactive power. Reducing reactive line losses by 50%-60% could save approximately 50 billion kWh of electricity annually, equivalent to half the power generated by the Three Gorges Dam. This type of project, which increases power generation without consuming primary energy, is an excellent green project. It requires minimal investment and yields rapid results.
3. Avoids fines. The Ministry of Electric Power and the Price Bureau of my country's "Notice on Issuing the Method for Adjusting Electricity Fees Based on Power Factor" stipulates that when the power factor is 0.94, the electricity fee will be reduced by 1.1%, and when the power factor is 0.6, the electricity fee will be increased by 15%.
