SVG reactive power compensation-Fornitore globale

1、 Reactive power compensation, also known as reactive power compensation, is a technology used in power supply systems to improve the power factor of the grid, reduce losses in power transformers and transmission lines, enhance power supply efficiency, and improve the power supply environment. So reactive power compensation devices are in an indispensable and very important position in the power supply system. Reasonable selection of compensation devices can achieve the maximum reduction of power grid losses and improve the quality of the power grid. On the contrary, improper selection or use may cause various factors such as power supply system, voltage fluctuations, and increased harmonics. Detailed introduction of the basic principles, significance, switching methods, circuits, controllers, high and low voltage devices, compensation methods, and existing problems of reactive power compensation.

2、 Advantages of SVG reactive power compensation device compared to other domestic products:

1. Compensation method: Domestic reactive power compensation devices basically use capacitors for reactive power compensation, and the compensated power factor is generally around 0.8-0.9. SVG uses power modules for reactive power compensation, and the power factor after compensation is generally above 0.98. This is currently the most advanced power technology internationally, and we are the only one in China who has mastered this technology; 2. Compensation time: The fastest time for domestic reactive power compensation devices to complete a compensation is 200 milliseconds, while SVG can complete a compensation in 5-20 milliseconds. Reactive power compensation needs to be completed instantly. If the compensation time is too long, it will result in a situation where there is no reactive power when it should be needed, and when it should not be needed, it will come back instead; 3. Graded and infinite: Domestic reactive power compensation devices generally use 3-10 levels of graded compensation, with tens of thousands of methods for each level increase or decrease, which cannot achieve precise compensation. SVG can perform infinite compensation starting from 0.1 kilofarads, fully achieving precise compensation; 4. Harmonic filtering: Domestic reactive power compensation devices use capacitive capacitors, which amplify harmonics themselves, so they cannot filter out harmonics at all. SVG does not generate harmonics, let alone amplify them, and can filter out more than 50% of harmonics; 5. Service life: Domestic reactive power compensation devices generally use contactors or thyristors for control, resulting in a short service life of about three years, high self loss, and frequent maintenance. SVG has a lifespan of over ten years, minimal wear and tear, and requires minimal maintenance.
